Last reviewed: September 2026
Next review trigger: Port Hedland first ammonia bunkering trial completion (Pilbara Ports, planned Q4 2026) or IMO Net-Zero Framework entry into force (2027), whichever occurs first.
Executive Summary
Only 3% of the 75 ports surveyed by IAPH in its 2025 World Ports Tracker report operational green ammonia bunkering rules — a market where 130 ammonia-fuelled and 225 ammonia-ready vessels are on order against fewer than five confirmed bunkering ports globally.
Rotterdam and Ulsan are the only two ports with verified commercial bunkering operations for ocean-going vessels: Rotterdam transferred 800 m³ of liquid ammonia ship-to-ship in April 2025 (MAGPIE safety confirmation, May 2026) and Ulsan supplied 600 tonnes via port-to-ship in April 2026 — the world's first commercial ammonia bunkering operation for a deep-sea vessel, carried out by Lotte Fine Chemical (Ulsan Port Authority, April 2026).
India's three leading port candidates — Paradip (₹797.17 crore jetty approved, 4 MTPA capacity), Deendayal/Kandla (3,400 acres, 3.5 MTPA jetty), and VOC Tuticorin (205.72 acres allocated) — are all Tier 3 infrastructure-development assets. No Indian port has completed a verified commercial ammonia bunkering operation for an ocean-going vessel. Executives deploying ammonia-fuelled vessels in 2026–2027 face a market with fewer than five operationally confirmed bunkering ports; this report provides the evidence framework to plan around that constraint.
Executive Intelligence Synthesis
Executive Intelligence Synthesis
Five commercial signals define the global green ammonia bunkering market in 2026. Only Rotterdam and Ulsan have documented operational bunkering capability for ocean-going vessels. 130 ammonia-fuelled vessels are on order against fewer than five operational ports. Ammonia availability at a port does not equal certified green ammonia marine-fuel availability.
India's major ports are supply nodes, not operational bunkering hubs. The IMO's 2027 mandatory framework converts port selection into a compliance decision, not only a cost decision.
Signal 1
FINDING: Only 2 global ports — Rotterdam and Ulsan — have produced verified, documented evidence of commercial green ammonia bunkering operations for ocean-going vessels as of September 2026.
SO WHAT: A shipping executive deploying an ammonia-fuelled vessel today has a choice of two operationally confirmed primary bunkering ports across the entire globe — a supply network so concentrated it represents a material commercial risk on any multi-voyage route plan.
NOW WHAT: Fleet deployment planning for ammonia-fuelled vessels commissioned in 2026–2027 must be anchored to Rotterdam and Ulsan as the only Tier 1 infrastructure; any other port must carry a contingency bunkering scenario until its commercial readiness is independently verified.
Signal 2
FINDING: 130 ammonia-fuelled and 225 ammonia-ready vessels have been ordered or announced globally (IMO and Ammonia Energy Association, March 2025), with the first larger ammonia-fuelled vessels entering commercial service in 2026–2027.
SO WHAT: DNV estimates the first phase of commercial ammonia bunkering will be served by approximately a dozen ports; at current infrastructure development rates, incoming vessel demand will structurally exceed confirmed bunkering capacity through at least 2028.
NOW WHAT: Operators with ammonia-fuelled vessels on order should secure bunkering agreements with Tier 1–2 ports before Q2 2027 — the window before vessel delivery and port capacity constraints interact.
Signal 3
FINDING: Approximately 170 ammonia terminals operate globally (IEA, 2026), yet the overwhelming majority handle conventional grey ammonia — not certified renewable marine fuel meeting the lifecycle emissions standards required by FuelEU Maritime.
SO WHAT: A port with ammonia handling infrastructure is categorically different from a port offering certified green ammonia bunkering; conflating the two is the single most common error in existing market commentary and the most commercially dangerous assumption in fleet fuel planning.
NOW WHAT: Vessel charter contracts and fuel-supply agreements drafted now must include explicit certification requirements specifying renewable origin, lifecycle GHG calculation methodology, and acceptable documentation standard — not simply "ammonia fuel."
Signal 4
FINDING: India's three leading port candidates — Paradip, Deendayal/Kandla, and VOC Tuticorin — are infrastructure development assets; no verified commercial ammonia bunkering operation for an ocean-going vessel had been completed at any Indian port as of September 2026.
SO WHAT: India's role in the global green ammonia supply chain is a production and export story, not a bunkering story — at least until 2029 at the earliest; treating Indian ports as near-term bunkering alternatives to Rotterdam or Singapore in fleet planning carries operational risk.
NOW WHAT: Infrastructure investors should track India's port-level regulatory approvals — not construction progress — as the leading indicator; the missing element is not jetty capacity but a port-specific marine-fuel ammonia bunkering framework equivalent to Singapore's Technical Reference published in Q2 2026.
Signal 5
FINDING: The IMO's Net-Zero Framework, designed to enter into force in 2027, will introduce mandatory fuel-intensity requirements and an economic mechanism for international shipping, compressing the window for operators to finalise their alternative-fuel bunkering strategies.
SO WHAT: Port selection is no longer purely a cost and logistics decision — it is a regulatory compliance decision; operators whose vessels call at EU ports already face FuelEU Maritime's progressive GHG intensity reductions (applied since 1 January 2025), and the IMO framework extends that logic globally from 2027.
NOW WHAT: Every ammonia bunkering strategy developed after Q4 2026 must be stress-tested against the IMO 2027 mandatory framework — not only against current commercial port availability.
2. Macro Context & Strategic Drivers
Macro Context
Three regulatory forces are driving investment in green ammonia bunkering infrastructure in 2026. IMO's MSC.1/Circ.1687 Interim Guidelines provide the international safety framework for ammonia-fuelled vessels. The EU's FuelEU Maritime regulation has applied since 1 January 2025, progressively reducing GHG intensity for ships above 5,000 GT calling at EU ports from 2% in 2025 to 80% by 2050. The IMO Net-Zero Framework, targeting 2027 entry into force, introduces mandatory fuel-intensity requirements and an economic mechanism — making port selection a compliance decision, not only a cost one.
2.1 The IMO Regulatory Architecture
FINDING: IMO's MSC.1/Circ.1687 Interim Guidelines for the Safety of Ships Using Ammonia as Fuel constitute the principal international safety instrument for ammonia-fuelled vessels in 2026, supplemented by additional interim guidance on ammonia-fuel training and cargo-used-as-fuel operations approved at MSC 111 in May 2026.
SO WHAT: These are interim guidelines, not a mature dedicated marine-fuel code; every port currently operates under a different national interpretation of these standards, creating regulatory fragmentation that is itself a commercial barrier to bunkering investment.
NOW WHAT: Vessel operators should verify that any port's safety framework specifically references MSC.1/Circ.1687 and has received explicit port authority approval — not merely adopted a general ammonia-handling standard.
Robert Masse, Lead of the Low Carbon GIA Alternative Low- and Zero-Carbon Fuels Workstream at IMO GreenVoyage2050, stated on 4 March 2026:
"This review of the regulatory framework for conventional and low-GHG-emission fuels is essential for any stakeholder involved in fuel production to fully understand regulatory requirements and the barriers that may arise from the absence of regulation or guidelines yet to be developed."
The IMO's own language confirms that regulatory gaps remain — a material constraint for port operators seeking commercial bunkering approval.
The EU's Alternative Fuels Infrastructure Regulation (AFIR), Regulation (EU) 2023/1804, establishes the broader framework for alternative-fuel infrastructure at European ports, including maritime ammonia and methanol. In February 2025, the European Commission announced €422 million for 39 alternative-fuel infrastructure projects, including maritime ammonia and methanol infrastructure — direct evidence that policy capital is moving from planning into commitment.

Australia | Port-level initiatives; existing dangerous-goods frameworks | No single national ammonia-bunkering regulation identified |
2.2 The Vessel Orderbook — Demand Creating Infrastructure Pressure
Jason Stefanatos, Global Decarbonisation Director at DNV Maritime, writing on 6 May 2026, observed:
"The ordering of four ammonia-fueled vessels in the bulker segment also stands out. While ammonia is still at an early stage as a marine fuel, projects like this — and the operational experience gained from them — are essential for moving the industry from concept to capability and taking practical steps towards wider adoption."
Earlier, Knut Ørbeck-Nilssen, CEO of DNV Maritime, stated on 3 September 2025:
"The groundwork for ammonia as a fuel is being laid, and the orderbook proves it's no longer just a theoretical fuel."
(DNV, Ammonia in Shipping: Tracing the Emergence of a New Fuel, September 2025.)
The commercial implication is structural. DNV's report describes a first phase involving a pioneering fleet bunkering from approximately a dozen ports before broader global infrastructure scaling. With fewer than five verified operational bunkering ports as of September 2026, the gap between the incoming vessel fleet and available port infrastructure will widen before it narrows.
2.3 The Demand-Infrastructure Catch-22
Rotterdam's March 2026 market consultation on investment in hydrogen-carrier terminals identified four structural barriers: demand uncertainty, policy uncertainty, grid congestion, and insufficient pipeline infrastructure. The catch-22 is self-reinforcing: without committed vessel orders, bunker demand is uncertain; without confirmed bunkering infrastructure, vessel operators defer ammonia commitments; without vessel demand, port infrastructure investment stalls. Breaking this cycle requires either large-scale policy intervention — the Norwegian Enova model at scale — or a fleet operator willing to bear first-mover infrastructure risk. Rotterdam and Ulsan have demonstrated that the technical problem is solvable. The coordination problem is not.
3. The GFJ Global Ammonia Port Readiness Index
Port Readiness Index
The GFJ Global Ammonia Port Readiness Index classifies world ports into five tiers based on verified evidence. Tier 1 (Commercially Demonstrated) contains Ulsan (approximately 600 tonnes port-to-ship, April 2026, Lotte Fine Chemical / Ulsan Port Authority) and Rotterdam (800 m³ STS, MAGPIE safety confirmation May 2026). Singapore is Tier 2 (Operational Trial) following ZETA Bunkering's MPA authorisation of 15 May 2026. Indian and Australian Pilbara ports are Tier 3. The IAPH 2025 World Ports Tracker confirms only 3% of 75 surveyed ports report operational ammonia bunkering rules.
3.1 The Port Readiness Evidence Framework — 14 Criteria
FINDING: No single authoritative global dataset classifies ammonia bunkering ports into operational, commercial, demonstration, under-construction, FEED, and announced categories — a gap explicitly acknowledged by IMO's own ongoing global infrastructure study.
SO WHAT: Every existing "ammonia port list" conflates these fundamentally different capability levels, systematically misleading executives about commercial availability.
NOW WHAT: The GFJ Port Readiness Evidence Framework provides the consistent 14-criterion lens for assessing any port claim; apply it before any bunkering commitment.
Each port is assessed against the following criteria as Present / Partial / Absent / Unknown:
1. Physical ammonia storage at or adjacent to berth
2. Green-certified ammonia supply available
3. Fuel certification pathway defined
4. Bunker delivery method in place (STS / truck-to-ship / shore-to-ship)
5. Bunker vessel or barge available
6. Vessel class demonstrated (ocean-going / coastal / none)
7. Volume demonstrated (tonnes or m³)
8. Safety and risk-assessment framework approved
9. Emergency-response plan in place
10. Regulatory approval for commercial operations
11. Recurring commercial availability (yes / trial only / planned)
12. Confirmed ammonia-fuel vessel calls recorded
13. Scalability evidence (multiple vessel calls per year)
14. Next verified infrastructure milestone (with timeline)
Criterion | Rotterdam | Ulsan | Singapore | Paradip (India) | Port Hedland (Aus) |
1. Storage at berth | ✓ Present | ✓ Present | Partial | Partial | ✗ Absent |
2. Green-certified supply | Partial (H2Global) | Not confirmed | In development | ✗ Absent | ✗ Absent |

6. Ocean-going demonstrated | ✓ Yes | ✓ Yes | Trial only | ✗ No | ✗ No |
7. Volume demonstrated | 800 m³ | ~600 tonnes | 9.74 tonnes | None | None |
8. Safety framework | ✓ MAGPIE | ✓ Approved | MPA authorised | ✗ Absent | ✗ Absent |
9. Emergency-response plan | ✓ Present | Not confirmed | In development | ✗ Absent | ✗ Absent |
10. Regulatory approval | ✓ Present | ✓ Present | Trial only | ✗ Absent | ✗ Absent |
11. Recurring commercial | ✓ Yes | ✓ Yes | Trial only | Planned 2028+ | Planned 2026 trial |
12. Vessel calls recorded | ✓ Yes | ✓ Yes | Yes (trial) | None | None |

14. Next milestone | Commercial scale-up | Multi-vessel ops | Commercial ~2027 | Jetty compl. 2027–28 | First trial 2026 |
3.2 The Five-Tier Classification
Tier | Classification | Definition | Ports (Sep 2026) |
Tier 1 | Commercially Demonstrated | Completed bunkering for ocean-going commercial vessel; commercial supply recurring or near-recurring; safety framework validated | Ulsan (~600t PTS, Apr 2026, Lotte Fine Chemical); Rotterdam (800 m³ STS, MAGPIE confirmed May 2026) |
Tier 2 | Operational Trial / Near-Commercial | Completed authorised bunkering trial; safety and regulatory framework advancing; commercial availability within 12–24 months | Singapore (ZETA/ITOCHU trial authorised 15 May 2026; 9.74t prior trial) |
Tier 3 | Infrastructure Under Development | Physical infrastructure committed or under construction; no bunkering trial completed | Paradip (India); Deendayal/Kandla (India); VOC Tuticorin (India); Port Hedland/Dampier (Australia); Point Tupper (Canada) |
Tier 4 | Project / Announcement Stage | MoU, FEED, feasibility study, or policy commitment; no committed physical infrastructure confirmed | Khalifa Port (UAE); multiple US ports; selected EU secondary ports |
Tier 5 | No Verified Capability | No authoritative evidence of ammonia marine-fuel bunkering infrastructure or approvals | Majority of global ports — IAPH: 39% no action, 37% not applicable (75-port survey, 2025) |
METHODOLOGY NOTE — GFJ Global Ammonia Port Readiness Index
Classifications are based exclusively on verified institutional evidence — port authority publications, regulatory filings, IMO documentation, and named company announcements with identified sources — available as of September 2026. No classification relies on self-reported port surveys, commercial press releases without corroborating sources, or projected capabilities. Where evidence is insufficient to classify a port at any tier, it is listed as unassessed. This index applies structured analyst judgment to documented capability evidence, not a quantitative scoring model. The 14 criteria were derived from Rotterdam's MAGPIE operational framework, IAPH's PRL-MF, and IMO's MSC.1/Circ.1687. Classifications will change as new bunkering operations are verified.
India-Specific Analysis: Supply Node or Bunkering Hub?
India Analysis
India's three principal port candidates for green ammonia bunkering — Paradip, Deendayal/Kandla and VOC Tuticorin — are Tier 3 (Infrastructure Development). Paradip has an approved ₹797.17 crore jetty with 4 MTPA capacity (MoPSW/Paradip Port, February 2026). VOC Tuticorin has an MoU with AM Green targeting 200,000 tonnes/year of marine ammonia bunkering by 2029–30 (AM Green corporate disclosure — verify at amgreen.in before publication). India is a strategic supply and export node in infrastructure development, not yet a commercially operational bunkering hub.
4.1 Indian Port Readiness Assessment
FINDING: All three of India's leading port candidates for marine ammonia bunkering are Tier 3 — infrastructure development underway, but no verified commercial bunkering operation completed as of September 2026.
SO WHAT: India's port infrastructure represents substantial committed capital, but capital commitment is not the same as commercial operational capability; a vessel requiring green ammonia bunkering in 2026–2027 cannot rely on an Indian port.
NOW WHAT: Track VOC Tuticorin's AM Green infrastructure development schedule and watch for the first port-specific bunkering regulatory approval from India's Ministry of Ports, Shipping and Waterways — that approval, not the jetty commissioning date, is the correct leading indicator for commercial viability.
Deendayal Port Authority (DPA) / Kandla has commissioned a 1 MW green-hydrogen plant, allocated 3,400 acres for green-hydrogen and green-ammonia projects, and developed a 3.5 MTPA jetty compatible with green-ammonia handling. The infrastructure scale is significant; the operational bunkering capability is not yet established.
Paradip Port received central government approval for a dedicated green-hydrogen and green-ammonia jetty at an estimated ₹797.17 crore, with 4 MTPA handling capacity including storage, pipelines and handling systems (approved February 2026). The jetty construction, commissioning, and port-level regulatory approval for marine-fuel bunkering operations are sequential steps, none of which is yet complete.
VOC Chidambaranar (Tuticorin) has allocated 205.72 acres for green-hydrogen and green-ammonia projects. AM Green has signed a memorandum of understanding with the port targeting up to 200,000 tonnes per year of marine ammonia bunkering capacity by 2029–30 (AM Green corporate disclosure — verify at amgreen.in before publication). VOC Tuticorin remains the most commercially specific of India's bunkering commitments.
Port | GFJ Tier | Key Infrastructure Data | Regulatory Gap | Earliest Bunkering Timeline |
Paradip | Tier 3 | ₹797.17 crore jetty approved, Feb 2026; 4 MTPA capacity | No port-level marine-fuel bunkering approval issued | 2028 at earliest (construction + approvals) |
Deendayal/Kandla | Tier 3 | 3,400 acres allocated; 3.5 MTPA jetty; 1 MW green-H₂ plant commissioned | No marine-fuel ammonia bunkering framework | 2028–2029 (conditional on framework) |
VOC Tuticorin | Tier 3 | 205.72 acres allocated; AM Green MoU, 200,000 t/year target (verify source) | MoU stage only; no construction commitment confirmed | 2029–30 per AM Green MoU target |
4.2 India's Regulatory Framework Gap
India's MNRE Green Ammonia Standard, introduced in February 2026, establishes the production-side definition of green ammonia. It does not constitute a port-level marine-fuel bunkering regulatory framework. India currently lacks the equivalent of Singapore's Technical Reference for Ammonia Bunkering (published Q2 2026), Rotterdam's MAGPIE-validated safety framework, or China's Temporary Rules for Technical Survey of Ammonia-Fuelled Ships (2026). Until India's Ministry of Ports, Shipping and Waterways (MoPSW) or another competent authority issues port-specific approvals for marine-fuel ammonia bunkering operations, commercial bunkering cannot proceed regardless of infrastructure completeness.
4.3 The India–Europe Green Ammonia Supply Corridor
AM Green and the Port of Rotterdam agreed in May 2025 to establish a green-energy supply chain connecting India with Northwest Europe, with the corridor potentially supporting up to 1 million tonnes per year of hydrogen-based fuels and products. This is a supply-chain development agreement, not evidence of marine bunkering capability. In June 2026, the ammonia-fuelled vessel Antwerpen completed its first commercial voyage from Nanjing carrying 30,214 tonnes of liquid ammonia toward India, illustrating the physical reality of ammonia cargo flows on routes that India's production base could eventually serve as a supply node.
4.4 Production vs Bunkering — The Critical Distinction
India's green ammonia ambitions are production- and export-oriented. The commercial question for vessel operators is not whether India produces green ammonia but whether that ammonia is:
(a) produced to the renewable standard required for marine-fuel lifecycle certification;
(b) physically available at a port in liquid bunker-ready form;
(c) supported by the documentation chain required for FuelEU Maritime or IMO compliance; and
(d) accessible through a port with regulatory approval for marine-fuel bunkering operations.
On all four dimensions, India's ports are not yet commercially usable for marine bunkering. The infrastructure investment underway addresses dimension (b). Dimensions (a), (c) and (d) remain unresolved.
5. Operational & Technical Deep-Dive
Technical Requirements
A port requires six core elements to commercially bunker an ammonia-fuelled vessel:
(1) liquid ammonia storage at or near the berth;
(2) a delivery mechanism — bunker vessel, shore pipeline, or truck-to-ship;
(3) an approved safety and emergency-response framework;
(4) regulatory authorisation for marine-fuel operations;
(5) qualified crew and port personnel;
(6) a fuel certification pathway confirming renewable or low-carbon origin.
Rotterdam's MAGPIE project (May 2026) confirmed that ship-to-ship bunkering is operationally feasible in an active port when all six elements are in place. Most global ports lack at least two.
5.1 The Three Bunkering Methods and Their Infrastructure Requirements
FINDING: Rotterdam's April 2025 demonstration transferred 800 m³ of liquid ammonia at –33°C ship-to-ship in approximately 2.5 hours — establishing that ship-to-ship bunkering is physically achievable in a busy commercial port environment.
SO WHAT: The ship-to-ship method requires a dedicated ammonia bunker vessel — Rotterdam's cost case estimates €50–75 million for the vessel and related investment (single-source figure; no independently verified comparable benchmark was located for this report) — creating a capital barrier that explains why most ports have not progressed beyond feasibility studies.
NOW WHAT: Port operators assessing bunkering investment should evaluate truck-to-ship as a lower-CAPEX entry point for early trial volumes before committing to a dedicated bunker vessel; Singapore's initial 9.74-tonne bunkering trial in 2024 (MPA Singapore) demonstrates that small-scale proof-of-concept operations can precede commercial infrastructure development.
The three available delivery methods carry materially different infrastructure requirements.
Ship-to-ship (STS) bunkering is the highest-throughput method, suitable for ocean-going vessels, but requires a purpose-built ammonia bunker vessel with its own storage, pumping, and vapour-return systems.
Shore-to-ship requires fixed pipeline infrastructure from shore storage to the vessel manifold — the highest fixed-infrastructure CAPEX.
Truck-to-ship is the most accessible method for trial volumes, requiring only a suitable berth, a truck with cryogenic ammonia tank, and the appropriate connection and safety equipment — but throughput is limited and it is not commercially viable for large deep-sea vessels requiring hundreds of tonnes per bunkering call.
5.2 Safety, Toxicity and the MAGPIE Findings
Ammonia's risk profile differs materially from LNG or methanol. It is toxic at low concentrations, corrosive to certain metals, and its release characteristics require different emergency-response protocols and exclusion-zone management than conventional marine fuels. Rotterdam's MAGPIE project — whose full results were published in May 2026 — confirmed that STS bunkering can be conducted safely in an active port environment, provided appropriate safety procedures, specialised equipment, and a clear regulatory framework are in place. The MAGPIE finding for port operators is not that ammonia is safe to bunker in the abstract — it is that ammonia can be bunkered safely when specific documented procedures are followed. Replicating this at a new port requires deliberate investment in procedures and equipment, not simply the physical presence of ammonia storage.
5.3 Green Certification — The Invisible Barrier
A vessel operator bunkering ammonia for compliance with FuelEU Maritime or the IMO Net-Zero Framework requires certified renewable or low-carbon fuel, not simply liquid ammonia.
The certification chain runs from: renewable electricity source → electrolysis → ammonia synthesis → transport and storage → lifecycle GHG calculation → delivery certificate meeting the applicable standard.
A port with conventional grey ammonia handling infrastructure cannot issue a compliant green fuel certificate. India's MNRE Green Ammonia Standard (February 2026) addresses the production-side definition, but the documentation chain to a ship's fuel receipt has not been established at any Indian port.

⚙ WORKED NUMERICAL EXAMPLE — Illustrative Bunkering Scenario | ||
Parameter | Value | Source / Label |
Voyage context (illustrative) | Rotterdam–Singapore–Rotterdam round voyage, Panamax bulk carrier (75,000 DWT, ammonia-fuelled main engine) — "MV Atlantic Pioneer" | Illustrative vessel parameters |
Round voyage distance | ~21,000 nautical miles | Illustrative |

Bunkering facility cost as % of total fuel cost | ~1–2% | Port of Rotterdam supply-chain cost case, Feb 2026 (single-source) |
Rotterdam (Tier 1): availability | Confirmed operational | MAGPIE, May 2026; Port of Rotterdam |
Singapore (Tier 2): availability for 2026–27 | Not confirmed; trial only until Q2 2027 at earliest | ITOCHU/MPA, May 2026 |
Indian port (Tier 3): risk as 2027 stop | HIGH — no commercial bunkering confirmed; no port-level regulatory approval issued | GFJ assessment, PIB / Paradip Port / MNRE (2026) |
Executive takeaway:
At H2Global reference pricing, the fuel cost for a single Rotterdam-anchored two-stop voyage is approximately €3 million. The bunkering infrastructure charge is marginal — under 2% of total delivered fuel cost. Production economics, not port CAPEX, dominate the commercial equation. Route plans that include an Indian port before 2029 carry unquantifiable bunkering risk.
6. Named Company Case Studies
Case Studies
Four companies are defining the commercial shape of green ammonia bunkering infrastructure in 2026. ITOCHU's ZETA Bunkering is conducting Singapore's first authorised ammonia bunkering trials (MPA authorisation effective 15 May 2026, up to two years). Yara Pilbara and Pilbara Ports are developing a low-carbon ammonia bunkering hub at Dampier and Port Hedland (MoU, March 2026). EverWind has received C$22.5 million in federal funding for a green-ammonia marine facility at Point Tupper, Nova Scotia (Transport Canada, March 2026). AM Green and Port of Rotterdam are building a supply chain targeting up to 1 million tonnes/year between India and Northwest Europe.
Case 1: ITOCHU / ZETA Bunkering — Singapore (Tier 2)
FINDING: Singapore's Maritime and Port Authority authorised ITOCHU's subsidiary ZETA Bunkering to conduct ammonia bunkering trials effective 15 May 2026, for up to two years — the first such authorisation under Singapore's regulatory framework.
SO WHAT: The authorisation is the formal trigger for Singapore's transition from feasibility to operational testing; the two-year window places the earliest realistic commercial service date at Q2 2027.
NOW WHAT: Operators targeting Singapore as a primary bunkering port for 2027 should engage directly with ZETA/MPA on trial outcomes before finalising charter agreements that depend on Singapore availability.
The trials test technical readiness, operating procedures, infrastructure adequacy, and ammonia bunkering technologies. Singapore had already recorded a 9.74-tonne ammonia bunkering trial in 2024 as a small-scale proof of concept. MPA announced in January 2026 that Singapore would publish its first Technical Reference for Ammonia Bunkering in Q2 2026 — the procedural backbone against which the ZETA trials operate.
Case 2: Yara Pilbara / Pilbara Ports — Port Hedland & Dampier (Tier 3)
FINDING: Pilbara Ports and Yara Pilbara signed an MoU on 5 March 2026 to develop a low-carbon ammonia bunkering hub at Dampier and Port Hedland, leveraging Yara's existing ammonia production capability in the Pilbara region of Western Australia.
SO WHAT: Unlike most announced bunkering initiatives that begin with an empty site and a project concept, this initiative starts with an operational ammonia producer adjacent to the proposed bunkering location — reducing supply-chain complexity and potentially accelerating the path from trial to commercial operation.
NOW WHAT: The first trial at Port Hedland was planned for 2026; operators targeting Australia-region bunkering should treat successful completion of that trial — not the MoU signing — as the first credible commercial readiness signal.
Samuel McSkimming, CEO of Pilbara Ports, stated on 5 March 2026:
"We're pleased to work alongside Yara Pilbara to promote the production of clean marine fuels in the Pilbara, and on ensuring WA plays a leading role in the global transition to low-emission shipping."
Laurent Trost, COO of Yara Pilbara, added the same date:
"The vision of the Pilbara as a bunkering hub offers great promise and we are excited to be part of the push to make it happen."
The commercial model is production-adjacent bunkering: Yara converts its existing ammonia production to a certified marine-fuel product and delivers it through port-side infrastructure co-developed with Pilbara Ports. The remaining gap is regulatory — Australia lacks a single national ammonia-bunkering regulation, and port-level approvals remain outstanding.
Case 3: EverWind — Point Tupper, Nova Scotia (Tier 3)
FINDING: Transport Canada confirmed a C$22.5 million federal contribution to EverWind for its Point Tupper Green Hydrogen and Green Ammonia Marine Facility in Nova Scotia, covering March 2026 to March 2029.
SO WHAT: Federal funding at this scale establishes Point Tupper as Canada's most credibly funded green-ammonia marine facility — but the project timeline to March 2029 means no commercial bunkering service before that date, and the evidence base confirms marine infrastructure development, not verified commercial bunkering capability.
NOW WHAT: Investors assessing North American green-ammonia marine infrastructure should treat EverWind as the leading Canadian indicator — but note that no authoritative source reviewed for this report verified any US or Canadian port as offering routine commercial green-ammonia bunkering operations as of September 2026.
Canada's broader green-ammonia export pipeline includes multiple proposed projects targeting more than 1 MTPA, 3 MTPA, and approximately 1 MTPA of ammonia production respectively (Canada Energy Regulator, 2026). These are export-oriented projects. Point Tupper is the single confirmed example of federal capital directed specifically at a marine facility.
Case 4: AM Green / Port of Rotterdam — India–Europe Corridor (Tier 3 / Supply Chain)
FINDING: AM Green and the Port of Rotterdam agreed in May 2025 to establish a green-energy supply chain connecting India with Northwest Europe, with the corridor potentially supporting up to 1 million tonnes per year of hydrogen-based fuels and products.
SO WHAT: This agreement is a supply-chain architecture commitment, not a commercial bunkering service; it establishes the potential for Indian-origin green ammonia to reach Rotterdam's bunkering infrastructure — but the physical supply chain, certification, storage, and commercial arrangements remain to be built.
NOW WHAT: The AM Green–Rotterdam corridor is the clearest indicator of the long-run India bunkering trajectory: India produces, Rotterdam bunkers — and eventually, as Indian port infrastructure matures, India bunkers too; watch AM Green's construction timeline at VOC Tuticorin as the single most commercially significant India-side milestone.
Rotterdam's February 2026 supply-chain cost case assumes a 1.2 Mtpa import/storage facility expandable to 3 Mtpa, with production accounting for 80–85% of total delivered fuel cost, transport and storage for 15–18%, and bunkering facilities for only 1–2%. These proportions — single-source, but analytically useful — confirm that green ammonia bunkering economics are dominated by production and transport costs, not by port infrastructure charges.
7. Friction, Risk & Systemic Bottlenecks
Systemic Bottlenecks
Five structural bottlenecks limit green ammonia bunkering commercial readiness in 2026: demand uncertainty creating a catch-22 for infrastructure investment (confirmed by Rotterdam's March 2026 market consultation); ammonia toxicity and safety complexity raising CAPEX and approval timelines; the absence of a standardised green-certification pipeline; regulatory fragmentation between IMO interim guidelines and national frameworks; and the gap between demonstration-scale operations and commercially scalable infrastructure, reflected in Lloyd's Register's Investment Readiness Level of 1 for ammonia bunkering and ports
(LR Zero Carbon Fuel Monitor — verify current values at lr.org/en/knowledge/research/zcfm/ammonia/).
FINDING: Rotterdam's March 2026 market consultation explicitly named four barriers to investment in hydrogen-carrier terminals — demand uncertainty, policy uncertainty, grid congestion, and insufficient pipeline infrastructure — confirming that even the most advanced operational port faces structural hesitancy about scaling.
SO WHAT: If Rotterdam, with its demonstrated operational capability and institutional backing, identifies demand uncertainty as a primary investment barrier, ports at Tier 3 and below face the same constraint multiplied by their lack of operational track record.
NOW WHAT: Breaking the demand-infrastructure catch-22 requires either large fleet commitments from vessel operators (creating demand) or substantial public subsidy on the infrastructure side — the Norway Enova model of funding up to 80% of investment costs (capped at NOK 150 million) is the most replicable policy instrument currently in evidence.
Bottleneck 1 — The Demand-Infrastructure Catch-22.
No vessels means uncertain bunker demand; uncertain demand means delayed infrastructure investment; delayed infrastructure means few ports able to support ammonia-fuelled vessels; few ports means vessel operators defer ammonia fuel commitments. Rotterdam's market consultation named this explicitly. It is not a future risk — it is the current state of the market outside the two Tier 1 ports.
Bottleneck 2 — Safety and Toxicity Complexity.
Ammonia requires procedures, equipment, and emergency-response capabilities materially different from LNG or conventional bunker fuels. The MAGPIE framework demonstrates that these requirements can be met — but meeting them at a new port requires deliberate investment before a single tonne of ammonia is delivered. China's Maritime Safety Administration noted in August 2026 that mature regulatory standards for ammonia-fuelled ships remain a challenge.
Bottleneck 3 — Green Certification is Not Standardised.
Approximately 170 ammonia terminals operate globally (IEA, 2026). The vast majority handle conventional grey ammonia.
No globally standardised certification chain from renewable electricity → green ammonia production → marine-fuel delivery certificate has been established.
Bottleneck 4 — Regulatory Fragmentation.
IMO's March 2026 regulatory mapping confirmed that development is progressing but gaps remain:
IMO interim guidelines + Singapore's Technical Reference + Rotterdam's MAGPIE framework + China's 2026 Temporary Rules + UK MCA case-by-case approach = no globally harmonised commercial bunkering framework. Vessel operators cannot apply a single compliance framework across bunkering stops on a global route.
Bottleneck 5 — The Scalability Gap.
A successful 600-tonne or 800 m³ demonstration does not validate weekly multi-vessel commercial bunkering. Lloyd's Register's Zero Carbon Fuel Monitor assigns ammonia bunkering and ports a Technology Readiness Level of 5, an Investment Readiness Level of 1, and a Community Readiness Level of 1
(LR Zero Carbon Fuel Monitor — verify current values at lr.org/en/knowledge/research/zcfm/ammonia/).
The gap between technical feasibility and commercial-scale infrastructure investment is not closing automatically.
8. Capital & Investment Implications
Investment Implications
Green ammonia bunkering infrastructure requires substantial capital. The Port of Rotterdam's February 2026 supply-chain analysis estimates €50–75 million for an ammonia bunker vessel and related investment (single-source figure). The EU mobilised €422 million for alternative-fuel maritime infrastructure projects in February 2025. Norway's Enova programme funds up to 80% of investment costs, capped at NOK 150 million. Production costs account for 80–85% of total delivered fuel cost in Rotterdam's model — making production economics, not port CAPEX, the dominant commercial driver of green ammonia's cost competitiveness as a marine fuel.
8.1 CAPEX Benchmarks
FINDING: Rotterdam's February 2026 green-ammonia supply-chain cost case estimates €50–75 million for a 10,000-tonne ammonia bunker vessel and associated infrastructure investment — the most specific publicly available CAPEX benchmark for a commercial ammonia bunkering operation as of September 2026.
SO WHAT: This figure rests on a single source (Port of Rotterdam, February 2026) and should be treated as a directional order-of-magnitude benchmark, not a project-planning figure; it is, however, sufficiently precise to establish that a commercial ammonia bunkering operation requires capital that individual port operators typically cannot absorb without public co-investment or policy support.
NOW WHAT: Infrastructure investors should use the Norway Enova model — up to 80% of investment costs, capped at NOK 150 million — as a benchmark for the public-subsidy ratio required to de-risk early-stage bunkering investment; this ratio implies a total project cost of approximately NOK 185–750 million (roughly €16–65 million, illustrative EUR conversion) for projects at or near the Enova cap.
⚠ Single-source disclosure:
The €50–75 million CAPEX figure is sourced exclusively from the Port of Rotterdam's February 2026 cost case. No second independent authoritative benchmark was located. Use as a directional estimate only.
8.2 Policy Funding Landscape
Public capital is moving into ammonia bunkering infrastructure at a pace that confirms commercial momentum. The EU's €422 million commitment (February 2025) for 39 alternative-fuel infrastructure projects spans maritime ammonia and methanol. Norway's Enova programme, offering up to 80% of investment costs capped at NOK 150 million, targets the first ammonia-fuelled vessels by 2027. India committed central government capital for Paradip's ₹797.17 crore jetty in February 2026. Canada channelled C$22.5 million through Transport Canada to EverWind's Point Tupper marine facility. Green bonds have demonstrated their viability for clean-energy infrastructure financing at scale; port operators can reference the growing sovereign and institutional green bond market when structuring project financing (for infrastructure financing analysis see GFJ: greenfueljournal.com/post/new-energy-m-a-playbook-2026-2027).
8.3 Fuel Economics — Delivered Green Ammonia Cost
IEA's low-carbon-fuel analysis estimates transporting ammonia 10,000 km by ship costs approximately $2–3/GJ, compared with $14–19/GJ for liquid hydrogen — confirming ammonia's structural advantage as a hydrogen carrier for long-distance maritime supply chains. IEA's projected total supply costs for 2030, including production and marine transport, range from $260–500/tonne for ammonia. The first H2Global green-ammonia import contract was priced at €1,000/tonne, with deliveries beginning in 2027.
METHODOLOGY NOTE — CAPEX Benchmark Disclosure
The €50–75 million CAPEX range is sourced exclusively from the Port of Rotterdam's February 2026 green-ammonia supply-chain cost case. No independently verified second authoritative benchmark was located for this report. This figure is labelled single-source throughout and should not be used as a project-planning benchmark without independent verification. The IEA projected 2030 supply cost ($260–500/tonne) and the H2Global first import contract price (€1,000/tonne) are not directly comparable metrics — they reflect different institutional contexts, time horizons, and measurement bases — and are presented separately, not as competing market prices.
8.4 Investment Risk Matrix
Port Tier | Project Stage | Risk Level | Recommended Investor Action |
Tier 1 (Rotterdam, Ulsan) | Operational | Low | Engage for capacity agreements; track scalability investments |
Tier 2 (Singapore) | Authorised trial | Medium-Low | Monitor ZETA trial outcomes; prepare heads-of-terms for post-trial commercial agreement |
Tier 3 — Regulatory pathway visible (Pilbara, EverWind) | Infrastructure development | Medium | Stage investment: commit to FEED; condition full investment on regulatory approval |
Tier 3 — Regulatory gap (India ports) | Infrastructure development | Medium-High | Track regulatory approval as lead indicator; do not commit bunkering capital until MoPSW framework is issued |
Tier 4 (announcement only) | MoU / FEED | High | Monitor only; no capital commitment until FID |
METHODOLOGY NOTE — Investment Risk Matrix
Risk ratings are derived from structured analyst judgment applied to four criteria: (1) the port's verified evidence of operational bunkering capability as classified in the GFJ Port Readiness Index; (2) committed capital and project stage; (3) regulatory approval status against the relevant national framework; (4) supply-chain maturity — whether a verified green-ammonia supply pathway has been documented. Ratings reflect verified public evidence as of September 2026 and should not be used as the sole basis for investment decisions. See legal disclaimer.
9. Future Scenarios & Forecast 2026–2035
Future Scenarios
Under the GFJ baseline scenario (55% probability), 3–5 commercial-grade green ammonia bunkering ports will exist globally by 2028, with DNV's projected first-phase network of approximately a dozen ports established by 2030–2032. The accelerated scenario (30% probability) requires the IMO 2027 mandatory framework to deliver investment certainty and Singapore to reach commercial service by end-2027. The prolonged demonstration scenario (15% probability) would leave fewer than 5 commercial ports operational by 2030 if demand uncertainty persists and infrastructure development in India, Australia and Canada stalls.
FINDING: The global green ammonia bunkering market in September 2026 sits in early Scenario B (Phased Rollout), with clear risk of slipping toward Scenario C (Prolonged Demonstration) if the IMO 2027 framework is delayed or if Singapore's ZETA trials produce operational complications.
SO WHAT: Fleet deployment decisions made in Q4 2026 and Q1 2027 will be made under Scenario B conditions — a world with 2 confirmed operational ports and one near-commercial trial port.
NOW WHAT: Hedge against Scenario C by ensuring charter agreements and fuel supply contracts include alternative-port provisions and fuel-flexibility clauses; the cost of these provisions is low compared with the commercial exposure if Scenario C materialises.
Scenario | Probability | Key Trigger Conditions | Port Count 2030 | India Commercial Bunkering |
A — Accelerated Deployment | 30% | IMO 2027 framework delivers investment certainty; Singapore commercial by end-2027; Port Hedland trial succeeds 2026 | 10–15 commercial-grade ports | VOC Tuticorin on schedule, 2029–30 |
B — Phased Rollout (Baseline) | 55% | 3–5 commercial ports by 2028; DNV first-phase dozen ports by 2030–2032; India at one port by 2031–32 | 8–12 commercial-grade ports | Operational at one port by 2031–32 |
C — Prolonged Demonstration | 15% | IMO delays; demand uncertainty persists; methanol displaces ammonia in 2027–2029 orderbook | <5 commercial ports | Deferred beyond 2032 |
METHODOLOGY NOTE — Scenario Probability Weights
Probability weights of 30% (Scenario A), 55% (Scenario B), and 15% (Scenario C) reflect structured analyst judgment applied to four factors: current pace of IMO regulatory implementation toward 2027 mandatory framework entry into force; ammonia-fuelled vessel orderbook commitment of 130 vessels (IMO, March 2025); infrastructure investment lead times derived from Rotterdam's and Singapore's documented timelines; and historical deployment trajectories for comparable alternative marine fuels. These are judgment-based probabilistic indicators, not actuarial outputs or quantitative model forecasts.
10. Strategic Recommendations
Strategic Recommendations
Shipping executives should restrict primary green ammonia bunkering plans for 2026–2027 to Rotterdam and Ulsan. Singapore (Tier 2) is the next viable option, contingent on ZETA Bunkering trial outcomes — earliest realistic commercial service date Q2 2027. Indian and Australian ports are Tier 3 infrastructure development assets; do not include them in primary bunkering strategy before 2029 without verified regulatory approval. Policymakers in India, Australia, and Canada should prioritise port-level regulatory frameworks — the missing element is not jetty capacity but marine-fuel bunkering approval.
For Shipping Industry — Vessel Operators and Fleet Managers
FINDING: The port availability constraint for ammonia-fuelled vessels in 2026–2027 is not primarily a cost problem — it is a physical availability problem: fewer than three ports globally can confirm commercial bunkering supply for an ocean-going vessel.
SO WHAT: Any fleet deployment plan that depends on more than two confirmed bunkering ports in 2026–2027 is built on infrastructure that does not yet exist commercially.
NOW WHAT: Finalise bunkering agreements with Rotterdam and Ulsan now; establish conditional heads-of-terms with Singapore contingent on ZETA trial completion; build alternative-fuel contingency provisions into all charter agreements signed before Q2 2027.
Map fleet deployment exclusively against Tier 1–2 ports for 2026–2027. Rotterdam and Ulsan are operationally confirmed. Singapore is the next credible option once trial completion is confirmed.
Include explicit green-ammonia certification requirements — renewable origin, lifecycle GHG calculation methodology, and acceptable documentation standard — in all vessel charter contracts and fuel supply agreements.
Monitor Singapore's ZETA Bunkering trial for commercial service announcement — Q2 2027 is the earliest realistic date based on the authorised two-year trial window from 15 May 2026.
Do not commit primary bunkering strategy to Indian ports before independent verification of port-specific bunkering regulatory approval from India's MoPSW. 2029 is the earliest credible date based on current infrastructure timelines.
For Port Operators and Infrastructure Investors
Apply the GFJ 14-criterion Port Readiness Evidence Framework as a capital planning checklist. Identify which criteria your port fails — and which represent the highest-value investment for moving up one tier.
Safety approval and regulatory timeline is consistently the longest lead item, not physical construction. Begin regulatory engagement before ground breaks.
Norway's Enova model — up to 80% infrastructure subsidy, NOK 150 million cap — is the strongest available policy precedent for de-risking early-stage bunkering investment. Track equivalent programmes in target geographies; the EU's €422 million infrastructure funding round confirms comparable mechanisms exist in Europe.
Green bonds have demonstrated viability for clean-energy infrastructure financing at scale. Port operators and sovereign entities should reference the growing institutional green bond market when structuring project financing.
For Policymakers — India, Australia, Canada, and Gulf
The infrastructure investment gap is not the primary constraint in any of these markets — the regulatory gap is. India needs a MoPSW- or MNRE-issued bunkering-specific regulatory framework before commercial operations can begin, regardless of how much jetty infrastructure is commissioned.
Singapore's Technical Reference for Ammonia Bunkering, published Q2 2026, provides a replicable template. A six-month regulatory adaptation exercise would immediately advance any Tier 3 port toward Tier 2 readiness.
Green certification standards must align with IMO fuel-intensity requirements and FuelEU Maritime's lifecycle GHG methodology. Fragmented national standards create a compliance dead-end that undermines bunkering infrastructure investment.
The commercial bunkering infrastructure gap for green ammonia is not primarily a technology problem — Rotterdam and Ulsan have proven the technology works. It is a coordination problem between regulatory frameworks, vessel orders, and infrastructure investment. Shipping executives and port authorities who solve that coordination challenge first will secure the only reliable bunkering infrastructure available in a market where fewer than five ports are operational and 355 vessels (130 ammonia-fuelled + 225 ammonia-ready ordered or announced, IMO/AEA, March 2025) have committed to ammonia as their long-term fuel.
11. Executive FAQ
Q: Which global ports can currently bunker green ammonia for ocean-going commercial vessels in 2026?
Rotterdam and Ulsan are the only two ports with verified commercial bunkering operations for ocean-going vessels as of September 2026. Rotterdam transferred 800 m³ ship-to-ship in April 2025, with safety confirmed by the MAGPIE project in May 2026. Ulsan Port Authority confirmed that Lotte Fine Chemical supplied approximately 600 tonnes via port-to-ship to the gas tanker Antwerpen on 23 April 2026. Singapore has authorised ZETA Bunkering trials for up to two years from 15 May 2026 but has not yet commenced commercial operations.
Q: What is the difference between an ammonia-ready port and a port where I can actually book commercial ammonia bunkering?
An "ammonia-ready" designation typically means a port has ammonia handling infrastructure — storage, pipelines, safety plans — but not necessarily the bunker vessel, green-certified fuel supply, or regulatory approval required for marine-fuel bunkering. The IAPH 2025 World Ports Tracker found only 3% of 75 surveyed ports report operational ammonia bunkering rules and procedures. A commercially bookable bunkering port requires all 14 criteria in the GFJ Port Readiness Evidence Framework — ammonia-handling infrastructure satisfies, at most, three or four of them.
Q: Can India's ports — Paradip, Kandla and Tuticorin — support ammonia bunkering for my vessels today?
No Indian port had completed a commercial ammonia bunkering operation for an ocean-going vessel as of September 2026. Paradip, Deendayal/Kandla, and VOC Tuticorin are all Tier 3 — infrastructure development underway, but no port-specific marine-fuel ammonia bunkering regulatory approval has been issued. The earliest credible commercial bunkering date at any Indian port is 2029, at VOC Tuticorin, conditional on AM Green construction progress and India issuing a port-level bunkering regulatory framework.
Q: What infrastructure does a port need before it can commercially supply green ammonia to a ship?
A port needs six core elements: liquid ammonia storage at or near the berth; a delivery mechanism (bunker vessel, shore pipeline, or truck-to-ship); an approved safety and emergency-response framework; regulatory authorisation for marine-fuel ammonia operations; qualified port personnel and crew; and a fuel certification pathway confirming renewable or low-carbon origin. Rotterdam's MAGPIE project (May 2026) confirmed all six can be assembled and operated safely. The single most commonly absent element at Tier 3–5 ports is regulatory authorisation, not physical infrastructure.
Q: Is the ammonia available at ports genuinely green and certified for FuelEU Maritime compliance?
Not automatically. Approximately 170 ammonia terminals operate globally (IEA, 2026), but most handle conventional grey ammonia with no climate compliance value under FuelEU Maritime. Certified green ammonia requires a documented chain from renewable electricity through electrolysis to a lifecycle GHG delivery certificate. Rotterdam has a certification pathway through the H2Global import mechanism (first contract: €1,000/tonne, deliveries from 2027). No Indian port had a verified green-ammonia certification pathway in place as of September 2026.
Q: How many commercial green ammonia bunkering ports will exist globally by 2030?
Under GFJ's baseline scenario (55% probability), 8–12 commercial-grade green ammonia bunkering ports will exist globally by 2030. The accelerated scenario (30% probability) produces 10–15 ports if the IMO 2027 mandatory framework delivers investment certainty and Singapore reaches commercial service by end-2027. The prolonged demonstration scenario (15% probability) yields fewer than 5 commercial ports. DNV's estimate of a first-phase network of approximately a dozen ports aligns with the baseline trajectory.
Research Limitations — Data Gaps Disclosure
No authoritative global port-by-port dataset classifies ammonia ports as operational, commercial, demonstration, under construction, FID, FEED, or announced. IMO's global infrastructure study is underway (country case studies expected Q4 2026).
No globally comparable commercial green-ammonia bunker-price dataset was found covering Rotterdam, Singapore, China, India, North America, and Australia on the same certification basis.
The Rotterdam €50–75 million CAPEX estimate is single-source (Port of Rotterdam, February 2026); no independently verified second authoritative benchmark was located.
No US port or Canadian port was verified as offering routine commercial green-ammonia bunkering as of September 2026.
No Gulf port was verified as providing routine commercial green-ammonia bunkering in the sources reviewed.
India's three leading ports have substantial infrastructure plans, but public authoritative evidence does not establish routine commercial green-ammonia bunkering at any Indian port.
The VOC Tuticorin 200,000 t/year AM Green MoU target originated in pre-research topic scoping; verify at amgreen.in or VOC Port official announcements before publication.
The Lloyd's Register TRL/IRL/CRL values for ammonia bunkering/ports cited in Section 7 originated in third-party analysis; verify current values at lr.org/en/knowledge/research/zcfm/ammonia/ before publication.
The Ulsan ~600-tonne commercial bunkering figure (23 April 2026, Lotte Fine Chemical, gas tanker Antwerpen, Ulsan Port Authority) is confirmed by Seatrade Maritime (4 May 2026), Maritime Executive (28 April 2026), and Marine Log (27 April 2026) — not drawn from an IMO or IRENA institutional dataset.
There is insufficient public data to calculate port-level utilisation rates for ammonia bunkering infrastructure or $/tonne bunkering cost by delivery method.
Public project announcements frequently combine ammonia production, storage, export and bunkering; project capacity should not be interpreted as bunkering capacity.
