Direct Air Capture: How DAC & Carbon Removal Markets Are Scaling in 2026

The phrase "direct air capture" appeared in only a handful of climate policy documents a decade ago. Today, it anchors the carbon removal strategies of governments, Fortune 500 corporations, and a rapidly expanding class of specialist technology companies. 2026 marks a genuine turning point — not because DAC has solved its cost problem, but because the sector has moved, decisively, from laboratory curiosity to infrastructure reality.

Consider what has happened in just the past two years. Climeworks switched on Mammoth in Iceland in May 2024 — the world's largest operational direct air capture plant at a design capacity of 36,000 tonnes of CO₂ per year. 1PointFive's Stratos facility in West Texas moved toward commissioning at a planned capacity of 500,000 tonnes per year, a figure that, if achieved, will represent an 873% surge in global DAC capacity in a single year.

The US Department of Energy disbursed $1.2 billion toward two large-scale DAC hubs. The European Union formalized its Carbon Removal Certification Framework (CRCF) in December 2024. Corporate buyers from Microsoft to Shopify have locked in multi-year purchase agreements worth hundreds of millions of dollars.

None of this means DAC is cheap, easy, or certain. The honest analysis is more complicated — and more interesting. This article provides that analysis: the technology, the economics, the policy landscape, the market structure, and the unresolved questions that will determine whether carbon dioxide removal scales to the billions of tonnes required by mid-century.

"Carbon removal is no longer a hypothetical. The question is no longer whether — it is how fast and at what cost."

What Is Direct Air Capture?

⬛ Quick Answer — Featured Snippet Optimized

Direct air capture (DAC) is an engineered process that uses chemical reactions to extract carbon dioxide (CO₂) directly from the ambient atmosphere. Unlike conventional carbon capture, which intercepts emissions at their source, DAC removes CO₂ that has already dispersed into the air. The captured CO₂ can be permanently stored underground or converted into useful products. DAC is a core negative emissions technology in global net-zero strategies.

DAC vs. Traditional Carbon Capture: A Fundamental Distinction

This distinction matters enormously for both engineering and policy. Point-source carbon capture and storage (CCS) attaches capture equipment to the exhaust stack of a power plant, cement kiln, or steel furnace — where CO₂ concentrations typically run between 10% and 30% of the flue gas. That high concentration means the thermodynamic work required to separate CO₂ is relatively modest. You are fishing in a concentrated stream.

Direct air capture fishes in the ocean. The concentration of CO₂ in ambient air is roughly 420 parts per million (ppm) — approximately 0.042%. Pulling a dilute gas out of an enormous volume of atmosphere demands far more energy and far more sophisticated chemistry. This fundamental physics is why DAC costs remain high, and why reducing those costs is such a rich area of current research.

However, the strategic value of DAC goes beyond any single facility. Point-source CCS can prevent new emissions from reaching the atmosphere — but it does nothing about the CO₂ already accumulated over two centuries of industrial activity.

DAC, in contrast, can address that historical carbon debt. It can operate anywhere on earth with access to low-carbon energy and a CO₂ storage or utilization pathway. And unlike nature-based carbon removal (forests, wetlands, soils), DAC offers durable, measurable, and highly permanent storage when paired with geological sequestration.

Key distinction: CCS prevents new CO₂ from entering the atmosphere. DAC removes CO₂ that is already there. Both are needed. Neither alone is sufficient for net zero.

How Direct Air Capture Works: The Technology Explained

⬛ Quick Answer

DAC systems use either liquid solvent or solid sorbent processes to chemically bind CO₂ from ambient air. Heat is then applied to release the CO₂ as a concentrated stream. That stream is compressed and either injected into geological formations for permanent storage or used to produce synthetic fuels, materials, or other products.

Liquid Solvent DAC (L-DAC)

In liquid solvent systems — pioneered by Carbon Engineering (now part of Occidental Petroleum's 1PointFive) — ambient air is drawn through large cooling-tower-style contactors and exposed to a strongly alkaline liquid, typically a potassium hydroxide (KOH) solution. The CO₂ reacts with the KOH to form potassium carbonate. This carbonate solution is then processed through a series of chemical steps — a pellet reactor, slaker, and calciner — to regenerate a concentrated CO₂ stream, which exits at high purity.

The process requires high-temperature heat (around 900°C), typically supplied by natural gas in current deployments, though renewable or low-carbon heat sources are increasingly being explored.

The advantage of liquid systems is scale. Large contactors can process enormous volumes of air, which is why the Stratos plant in Texas — using this technology — is targeting 500,000 tonnes per year. The tradeoff is energy intensity and capital cost. High-temperature heat is expensive to produce and to decarbonize.

Solid Sorbent DAC (S-DAC)

Solid sorbent systems — the approach used by Climeworks and Heirloom Carbon — use porous solid materials, often amine-functionalized compounds, that bind CO₂ from air at ambient temperature. When the sorbent is saturated, the system switches to a temperature-vacuum swing cycle: a combination of modest heat (around 80–120°C) and reduced pressure releases the CO₂ as a concentrated gas. The sorbent is then cooled and returned to capture mode.

Lower regeneration temperatures make solid sorbent systems more compatible with low-grade waste heat and renewable electricity. They also lend themselves to a modular design — Climeworks' Mammoth plant uses 72 collector containers, each a self-contained capture unit, which can be assembled and scaled like industrial Lego. The challenge is sorbent degradation over time and relatively lower air throughput per unit volume compared to liquid systems.

The Lifecycle of a Captured CO₂ Molecule

Understanding what happens after capture clarifies the value proposition of the entire system:

• Capture: CO₂ binds to liquid solvent or solid sorbent in the contactor/collector. Ambient air, at ~420 ppm CO₂, is the feedstock.

• Concentration & Release: Heat and/or pressure swing releases a high-purity CO₂ stream (typically >95% purity).

• Compression: The CO₂ stream is compressed to supercritical state for efficient pipeline transport or injection.

• Sequestration or Utilization: The compressed CO₂ is either:

  • Injected deep into geological formations (saline aquifers, basaltic rock) for permanent storage — as at Climeworks' Mammoth, where Carbfix mineralizes CO₂ into stone within two years; or

  • Used to produce synthetic fuels, chemicals, or building materials — though this pathway is only climate-beneficial if the energy powering the process is fully renewable.

Storage permanence matters: Geological mineralization, as practiced by Carbfix in Iceland, locks CO₂ into solid rock with a storage lifetime measured in thousands of years. This permanence is what separates high-quality DAC credits from lower-quality offset instruments in voluntary carbon markets.

Why Direct Air Capture Is Critical for Net Zero Goals

⬛ Quick Answer

The IEA Net Zero Emissions by 2050 Scenario requires DAC to capture over 85 million tonnes of CO₂ annually by 2030 and 980 million tonnes by 2050. This scale is necessary because some sectors of the economy — aviation, shipping, heavy industry — cannot eliminate emissions through electrification alone. DAC provides the residual offset that makes true net zero achievable.

The Problem of Hard-to-Abate Sectors

Much of the energy transition is proceeding on a clear technological roadmap. Electric vehicles are replacing combustion engines. Wind and solar are displacing coal and gas in electricity generation. Heat pumps are slowly replacing gas boilers. But a substantial portion of global emissions comes from sectors where eliminating CO₂ is either technically impossible or economically impractical with current technology alone:

• Aviation: Long-haul flights require energy-dense fuels. Battery-powered intercontinental aircraft remain decades away. Sustainable aviation fuels (SAFs) can reduce lifecycle emissions, but genuine carbon negativity requires either DAC-derived synthetic fuels or carbon removal offsets.

• Cement production: Around 60% of cement's CO₂ emissions are process emissions — a direct chemical byproduct of converting limestone to clinite — not combustion. You cannot eliminate them by switching to renewable energy. Carbon capture or DAC-based offsets are among the very few viable pathways.

• Steel and iron: High-temperature processes in blast furnaces are difficult to electrify at current costs. Green hydrogen-based direct reduction is promising but not yet deployed at scale.

• Shipping: Deep-sea container shipping operates on a decades-long asset cycle. Even with ammonia and methanol fuels entering the fleet, a large residual emissions burden will exist well past 2040.

For these sectors, direct air capture and other carbon dioxide removal (CDR) technologies serve a specific and irreplaceable function: they balance out emissions that cannot be reduced to zero. This is the logical foundation for the Voluntary Carbon Market's growing appetite for DAC credits.

The Carbon Debt Concept

Even if the world achieved net-zero emissions overnight — an impossibility, but a useful thought experiment — the CO₂ already accumulated in the atmosphere would continue to drive warming for decades. The atmosphere currently holds approximately 3,200 billion tonnes of CO₂, elevated by nearly 50% above pre-industrial levels. Climate models consistently show that meeting the 1.5°C target requires not just net zero, but net negative emissions during the second half of this century — actively drawing down the historical accumulation.

The IPCC Sixth Assessment Report (AR6, 2022) confirmed this: virtually every pathway that limits warming to 1.5°C relies on some deployment of carbon dioxide removal. The disagreement among scientists is not whether CDR is needed, but how much, when, and through which combination of approaches. DAC's role as the most controllable, scalable, and measurable form of engineered removal makes it the technology that anchors those projections.

DAC vs BECCS: Which Carbon Removal Technology Wins?

⬛ Quick Answer

BECCS (bioenergy with carbon capture and storage) currently costs less per tonne than DAC and can generate net energy, but requires vast land and water resources. DAC costs more but has a near-zero land footprint and unlimited theoretical scale. The most credible climate scenarios deploy both technologies as complements, not competitors.

Criterion	Direct Air Capture (DAC)	BECCS
Current Cost ($/tCO₂)	$400–$1,000+ (commercial operations, 2024–2025)	$20–$200 (varies widely by feedstock and geography)
Projected Cost by 2050	$100–$300 (optimistic learning-curve projections)	$50–$150 (limited by biomass feedstock constraints)
Energy Intensity	High: ~1,000–1,289 kWh per tonne CO₂ (electricity + heat)	Moderate: Can be energy-positive with high-quality biomass but often energy-neutral to negative in practice
Land Use	Minimal: 0.04–3.3 million ha for 12 GtCO₂/yr removal (DAC)	Massive: 363–2,100 million ha for equivalent removal capacity
Water Consumption	Moderate: ~2 tonnes water per tonne CO₂; highly location-dependent (humidity matters)	High: Large water input for biomass cultivation and processing
Storage Permanence	Very High: Geological storage offers 10,000+ year permanence	High: Geological storage if implemented; dependent on project design
Geographic Flexibility	Excellent: Can be sited anywhere with low-carbon energy and storage access	Limited: Requires specific agricultural land, climate zones, and supply chain logistics
Biodiversity Risk	Very Low	High: Large-scale monoculture biomass crops threaten biodiversity and food security
Technology Readiness Level (TRL)	TRL 8–9 (commercial demonstration, scaling)	TRL 7–8 (commercial demonstration in select projects)
Carbon Removal Integrity	High: Direct, measurable, attributable	Variable: Depends on biomass lifecycle accounting and land-use change emissions

Why Synergy Is the Right Frame

The question "DAC or BECCS?" is a false binary. The most rigorous climate modeling — including work published in Frontiers in Climate (2024) drawing on expert elicitation from 34 specialists — finds that BECCS costs start lower but decline more slowly, while DAC costs start higher but have steeper learning-curve potential. Different geographies, different biomass contexts, and different timescales will favor different choices.

Critically, BECCS faces hard resource limits: land for biomass cultivation is finite and contested by food, biodiversity, and other uses. DAC faces no such physical ceiling. Its ultimate constraint is energy availability — and as renewable energy continues to fall in cost and expand in deployment, DAC's economics improve in direct proportion.

A well-designed CDR portfolio in 2050 likely looks something like: BECCS deployed in regions with sustainably managed biomass (Scandinavia, parts of Brazil, Southeast Asia); DAC deployed near geological storage resources and low-cost renewable energy hubs; and nature-based solutions providing the biological carbon cycling layer beneath both.

Direct Air Capture Market Growth & Investment Trends (2024–2026)

⬛ Quick Answer

The global DAC market was valued at approximately $147 million in 2025 and is projected to reach $17.57 billion by 2035 at a CAGR of 61.3%. Over 6 million tonnes of carbon removal capacity has been secured through advance purchase agreements from corporate buyers, driving project development and de-risking investment in new facilities.

The Advance Purchase Agreement Revolution

Perhaps the single most important structural development in the DAC market is the rise of long-term advance purchase agreements (APAs). These contracts, in which buyers commit today to purchase CO₂ removal credits from plants not yet built, serve a function analogous to power purchase agreements in the renewable energy sector: they de-risk the capital investment and provide developers with revenue certainty needed to attract debt financing.

The landmark aggregation vehicle is Frontier, a consortium that committed $1 billion toward advance purchases of permanent carbon removal across multiple pathways, including DAC. Its founding members include Stripe, Alphabet, Shopify, Meta, and McKinsey. By aggregating demand from multiple corporate buyers, Frontier provides DAC developers with a more predictable revenue base than individual bilateral agreements.

Individual corporate commitments are also significant:

• Microsoft inked a 3.3 million tonne agreement with Stockholm Exergi (a BECCS project) and has made multiple DAC advance purchases through various developers.

• Amazon pledged to purchase 250,000 metric tonnes of carbon removal from 1PointFive's first DAC facility in Texas.

• JP Morgan Chase announced commitments totaling $200 million in high-quality, durable CDR agreements across multiple providers.

• Airbus, Shopify, Swiss Re, and UBS are among the growing roster of corporates purchasing DAC-sourced removal credits through Climeworks.

Market Size and Growth Trajectory

Multiple market research analyses converge on an extraordinary growth projection for DAC:

$147M DAC market size in 2025

$229M Projected market size in 2026

$1.7B Projected market size by 2030

$17.6B Projected market size by 2035

The Voluntary Carbon Market (VCM) and DAC's Role

The broader Voluntary Carbon Market has faced credibility challenges in recent years, as investigations revealed that many nature-based offset projects delivered far less removal than claimed. This credibility crisis has, paradoxically, accelerated interest in DAC-based credits. DAC offers what offset markets have struggled to provide: quantifiability, additionality, and permanence — the three pillars of high-integrity carbon removal.

When Climeworks injects CO₂ into basaltic rock in Iceland and independent third parties verify the volumes, there is no equivalent of the "ghost forest" problem that plagued REDD+ offset credits. The tonne removed is measurable, attributable, and permanent. This is why DAC credits command premium prices in the VCM — currently ranging from $400 to over $1,000 per tonne — and why institutional buyers with serious climate commitments are increasingly willing to pay them.

As of early 2026, the IEA notes that 84 DAC plants — combining pilots and commercial facilities — are expected to be operational, with a combined capacity of approximately 569,000 tonnes of CO₂ per year. By 2032, industry projections suggest 114 facilities with a combined capacity of 2.1 to 5.4 million tonnes per year.

Policy Drivers Accelerating Direct Air Capture

⬛ Quick Answer

Two policy instruments dominate global DAC investment in 2026: the US Section 45Q tax credit, which offers up to $180 per tonne of CO₂ permanently stored via DAC under the Inflation Reduction Act, and the EU's Carbon Removal Certification Framework (CRCF), adopted in December 2024, which creates the regulatory infrastructure for DAC credits to count toward national climate targets and enter compliance markets.

United States: The 45Q Tax Credit and DAC Hubs

The US policy architecture for DAC is the most advanced in the world, driven by two legislative pillars:

The 2022 Inflation Reduction Act (IRA) expanded the Section 45Q tax credit to offer $180 per tonne of CO₂ permanently stored via direct air capture — a figure explicitly designed to make large-scale DAC economically competitive within this decade. For context, the credit was $50 per tonne before 2022. The IRA also lowered the minimum capture threshold to just 1,000 tonnes per year, opening the credit to smaller and earlier-stage projects.

The 2021 Infrastructure Investment and Jobs Act allocated $3.5 billion to establish four large-scale DAC hubs, each targeting at least 1 million tonnes per year of CO₂ removal. In August 2023, the Department of Energy announced the selection of Project Cypress (Louisiana, led by Climeworks and Heirloom) and the South Texas DAC Hub (led by 1PointFive), together disbursing $1.2 billion in initial funding.

As of July 2025, the "One Big Beautiful Bill Act" signed into law preserved the 45Q credit at $180 per tonne for DAC with geological storage through 2026, with inflation adjustments thereafter.

The credit's transferability — allowing developers to sell credits to third parties — remains a critical mechanism for project financing, particularly for smaller operators without sufficient tax liability to use the credits directly.

The US also launched a $35 million CDR purchase pilot program, in which the federal government itself acts as an advance buyer of CDR credits — a powerful demand-creation signal that complements the supply-side incentives of 45Q.

European Union: The Carbon Removal Certification Framework

The EU has taken a regulatory rather than primarily fiscal approach to DAC. In February 2024, the European Parliament and Council reached provisional agreement on the Carbon Removal Certification Framework (CRCF), which was formally adopted in December 2024.

The CRCF establishes standardized methodologies for certifying carbon removal activities, including

DAC, against four quality criteria:

• Quantification: Removal must be measured with precision and verified against lifecycle assessments.

• Additionality: The removal must not have occurred without the intervention.

• Long-term storage: Geological storage (permanent) is distinct from temporary biological storage, with corresponding certification tiers.

• Sustainability: Activities must not cause significant harm to other environmental objectives.

The CRCF's significance extends beyond voluntary markets. Certified removal units can count toward nationally determined contributions (NDCs), and the European Commission has stated an ambition to store 50 million tonnes of CO₂ per year by 2030 — including contributions from DAC. Integration with the EU Emissions Trading System (EU ETS) is a medium-term prospect that could unlock compliance market demand orders of magnitude larger than the current voluntary market.

Other Jurisdictions

• Canada: A federal investment tax credit covering approximately 60% of DAC project costs when CO₂ is permanently sequestered, announced in the 2022 federal budget and progressing through legislation.

• Japan: A CCUS roadmap targeting 6–12 million tonnes per year of CO₂ capture by 2030, including DAC components.

• United Kingdom: DAC included in the Net Zero Strategy, with feasibility funding for early-stage projects.

Cost of Direct Air Capture: Is DAC Economically Viable?

⬛ Quick Answer

Current commercial DAC costs range from approximately $400 to over $1,000 per tonne of CO₂, far above the widely cited $100 per tonne target considered necessary for broad economic viability. The gap is real, but the learning-curve trajectory — driven by scale, engineering refinement, and cheaper renewable energy — offers a credible, if demanding, pathway to cost reduction over the next 15–20 years.

Why CO₂ Is So Hard to Catch from Air

The core physics of the cost problem deserves explicit explanation, because it shapes every other economic factor. The atmosphere contains roughly 420 ppm CO₂. That is 420 molecules of CO₂ for every million molecules of air — a ratio of approximately 1 in 2,380.

To capture one tonne of CO₂, a DAC facility must process approximately 1.8 million cubic metres of air. That requires enormous fans, large contact surface areas, and significant electricity.

By contrast, a coal-fired power plant's flue gas contains CO₂ at concentrations of 10–15%. The thermodynamic work of separating CO₂ from a 10% concentration is vastly lower than separating it from a 0.042% concentration. This is not an engineering failure — it is a fundamental property of entropy. The diluteness of atmospheric CO₂ imposes an irreducible energy cost that better chemistry can reduce but cannot eliminate.

Current Cost Breakdown

Cost Component	Approximate Share of Total Cost	Key Reduction Lever
Energy (electricity + heat)	~50–70%	Cheaper renewable energy; improved thermal integration
Capital equipment (amortized)	~15–25%	Manufacturing scale; standardized modular design
Sorbent / solvent replacement	~5–15%	Improved sorbent durability and regeneration cycles
Operations & maintenance	~10–15%	Automation; operational learning curves
CO₂ compression and transport	~5–10%	Infrastructure sharing; proximity to storage sites

IEA research indicates that DAC facilities can consume between 500 and 1,289 kWh of energy per tonne of CO₂ captured, depending on technology type and operating conditions. If that energy is sourced from fossil fuels, a significant portion of the captured CO₂ is simply offset by the emissions from energy production — which is why pairing DAC with truly low-carbon energy is not optional but essential for delivering genuine climate benefit.

The Path to $100/tonne

The $100 per tonne figure is cited so frequently because it approximates the level at which DAC could compete meaningfully with other mitigation strategies and participate in mainstream carbon markets at scale. Reaching it is not simply a matter of more investment — it requires a convergence of several learning curves simultaneously:

• Renewable energy cost reductions continue to make DAC's energy input cheaper. Solar electricity in optimal locations now costs less than $20/MWh — a level that materially changes DAC's energy economics.

• Manufacturing scale reduces capital costs per tonne through supply chain maturation and standardized production. Climeworks' modular collector containers are designed specifically to exploit this effect.

• Sorbent chemistry innovation can improve CO₂ loading capacity and reduce regeneration energy requirements.

• Operational learning improves plant availability and reduces maintenance costs with experience.

Notably, Climeworks' own 2024 assessment does not project significant cost reductions before 2030 — a more cautious position than some academic projections. This reflects the reality that early commercial operation has revealed engineering challenges not fully captured in theoretical models. Cost reduction is real but nonlinear, and the pace depends heavily on deployment scale — which in turn depends on policy and market development.

Challenges & Skepticism: Addressing the Hard Questions

⬛ Quick Answer

The principal legitimate critiques of DAC center on its high energy demand, current high cost, and the risk that over-reliance on future CDR could slow near-term emissions reductions. These are serious concerns that deserve serious answers — not dismissal. However, they argue for careful deployment strategy alongside DAC, not against DAC itself.

The Energy Demand Problem

The numbers are not small. Meeting the IEA's 2050 scenario of 980 million tonnes per year of DAC removal would require energy inputs in the range of 500–1,000 EJ per year at current efficiency levels — comparable to a substantial fraction of current global primary energy consumption. Even with efficiency improvements, scaling DAC to climatically relevant levels requires a massive expansion of low-carbon electricity and heat.

This is not an argument against DAC — it is an argument for rapid deployment of renewable energy alongside DAC infrastructure. The two imperatives reinforce rather than compete with each other. DAC can, in fact, serve as a productive use case for excess renewable electricity during periods of grid oversupply, running its energy-intensive processes when power prices are lowest.

The "Moral Hazard" Argument

Some critics argue that the promise of future large-scale DAC creates a moral hazard: it allows fossil fuel interests and policymakers to slow emissions reductions today, on the implicit assumption that carbon removal will fix the problem later. This is a legitimate concern, and it is not hypothetical — carbon removal has appeared in scenarios used by some oil companies to justify continued hydrocarbon production.

The answer is not to dismiss CDR, but to insist on its role as a complement to rapid emissions reduction rather than a substitute for it. The IPCC, the IEA, and the broader scientific community are explicit on this point: CDR fills the residual gap that cannot be closed by emissions reduction alone. It does not justify delaying that reduction. This distinction is critical, and responsible DAC developers and advocates consistently emphasize it.

Geological Storage: Scale and Permanence

Storing hundreds of millions of tonnes of CO₂ underground every year requires substantial geological storage capacity and injection infrastructure. The IEA projects that existing and planned CO₂ pipeline networks will reach a surplus capacity of 420 million tonnes per year by 2030 — meaningful, but short of the 1,200 million tonnes per year the Net Zero Scenario requires by that date.

Developing more geological storage, verifying its integrity, and building the associated injection wells and pipeline networks represents a significant parallel infrastructure challenge.

Is DAC a "Distraction"?

The most pointed version of the skeptical argument holds that the financial and political attention devoted to DAC crowds out investment in simpler, cheaper solutions: energy efficiency, building retrofits, direct renewable energy deployment. This argument has some traction at the margins of the climate policy debate.

A balanced assessment recognizes that climate change is not a problem solvable by a single technology or policy instrument. The decarbonization challenge is large enough that the world simultaneously needs efficiency, renewables, industrial transformation, and — for the residual problem — carbon removal. The question is not whether to do DAC, but how to do it without it becoming an excuse for slower action on emissions at the source.

Real-World Case Studies: DAC in Operation (2026 Update)

⬛ Quick Answer

Three landmark projects define the current state of commercial DAC: Mammoth in Iceland (operational since May 2024, 36,000 tCO₂/yr capacity), Stratos in Texas (the world's largest planned DAC plant at 500,000 tCO₂/yr), and a growing cluster of European DAC hubs supported by the CRCF. Together, these projects are generating the operational data needed to validate cost reduction assumptions.

Mammoth — Hellisheiði, Iceland (Climeworks)

Climeworks launched its Mammoth plant on May 8, 2024, at the Hellisheiði geothermal park in Iceland. Designed for a nameplate capacity of 36,000 tonnes of CO₂ per year, Mammoth is approximately ten times larger than its predecessor, Orca, which began operations in 2021.

The plant uses 72 modular collector containers — each containing solid sorbent materials — arranged in distinctive V-shaped wing configurations. Power is supplied entirely by Iceland's geothermal energy grid, operated by ON Power, ensuring near-zero lifecycle emissions from the energy input.

Captured CO₂ is delivered to storage partner Carbfix, which injects it 700 metres underground into basaltic rock formations, where it undergoes natural mineralization and solidifies into stone within approximately two years. This mineralization process represents one of the most permanent and verifiable forms of carbon storage available.

Climeworks processed close to 200 million data points daily from its earlier plants. Those operational learnings are embedded in Mammoth's design. The company remains on a roadmap toward megaton capacity by 2030 and gigaton scale by 2050. Three megaton-scale proposals in the United States — including Project Cypress in Louisiana — have been selected by the DOE for funding totaling over $600 million.

Stratos — Permian Basin, Texas (1PointFive / Occidental)

The most ambitious commercial DAC project currently under development is Stratos, built by 1PointFive, a subsidiary of Occidental Petroleum, in the arid landscapes of West Texas. At a designed capacity of 500,000 tonnes per year, Stratos would represent an almost tenfold expansion over Mammoth and would alone account for the majority of global DAC capacity upon full operation.

Stratos uses Carbon Engineering's liquid solvent technology, which requires high-temperature heat and therefore uses natural gas in its initial configuration. This has drawn scrutiny from some analysts who point out the carbon accounting complexity of using fossil fuel combustion to power a carbon removal process. Occidental has also referenced using captured CO₂ for enhanced oil recovery (EOR), which critics argue complicates the climate benefit. The company maintains that all captured CO₂ is ultimately stored underground — and that initial natural gas combustion is a transition step toward decarbonized heat sources.

Despite these debates, Stratos is generating the scale-up data the entire industry needs. The South Texas DAC Hub — a future facility in the same region, targeting 1 million tonnes per year — received DOE funding in 2023 and is in early development.

European DAC Hubs

Europe is developing a cluster of DAC projects enabled by the CRCF and existing carbon market structures:

• Mission Zero (UK): Closed a GBP 21.8 million funding round in 2024 to scale its proprietary electrochemical DAC technology, which aims to reduce energy intensity relative to thermal-swing processes.

• RepAir + EnEarth (Greece): Signed an agreement in June 2024 to use RepAir's DAC technology to capture CO₂ and store it in the Prinos saline aquifer in Kavala, Greece — one of the first DAC projects to use offshore geological storage in the Mediterranean.

• Kollsnes DAC Project (Norway): A megaton-scale development leveraging Norway's North Sea geological storage infrastructure and the country's abundant hydropower resources.

• Carbyon (Netherlands): Working on next-generation solid sorbent materials with improved kinetics and lower regeneration temperatures, targeting significant cost reduction by the late 2020s.

Frequently Asked Questions About Direct Air Capture

Is Direct Air Capture worth it, or is it too expensive?

At current costs of $400–$1,000+ per tonne, DAC is genuinely expensive by comparison with most emissions reduction options. However, the relevant comparison is not "DAC vs. solar panels" — it is "DAC vs. doing nothing about the CO₂ already in the atmosphere and the emissions from hard-to-abate sectors."

For those residual emissions, DAC is one of very few technically viable options. The cost question is therefore less "is it worth it in absolute terms?" and more "is the learning curve fast enough and the scale-up achievable?" Evidence from 2024–2026 suggests the technology is real and improving — but the pace of cost reduction remains uncertain.

The combination of the 45Q tax credit, corporate advance purchases, and improving renewable energy economics makes continued investment rational for the climate goals we need to meet by 2050.

Can DAC actually remove enough CO₂ to impact climate change?

Not at current scale — but scale is not the current goal. As of 2026, all operational DAC plants combined remove well under 1 million tonnes of CO₂ per year, compared to global annual emissions of approximately 37 billion tonnes. That gap is enormous.

However, the purpose of current deployments is to reduce costs, improve operations, and build supply chains — exactly what solar photovoltaics did in the 2000s and 2010s. The IEA's Net Zero Scenario requires DAC to remove 85 million tonnes per year by 2030 and 980 million tonnes by 2050. Whether the learning curve is steep enough to get there in time is the central open question in CDR policy. The technology can physically do the job. The challenge is speed and economics.

Is DAC a scam, or is it a real climate solution?

DAC is demonstrably real technology that demonstrably removes CO₂ from the atmosphere, verified by independent third parties using internationally recognized methodologies. The companies operating commercial plants — Climeworks, 1PointFive, Heirloom — publish lifecycle assessment data, accept third-party audits, and provide transparent reporting of actual removal volumes. It is not a scam. Where the legitimate criticism lands is on scale and cost: current DAC cannot solve climate change at current scale and current cost.

Advocates who suggest otherwise are overstating the technology's near-term impact. Advocates who dismiss it entirely because it is not yet cheap or large are applying a standard that would have ruled out solar energy in 2005. The honest answer: it is a real, necessary, currently expensive, and improving technology that forms one part — not all — of the solution.

What is the future of carbon removal markets?

Carbon removal markets are moving toward greater institutionalization and higher quality standards. The EU's CRCF (December 2024) represents the first major regulatory framework to standardize removal certification at scale. Integration with compliance markets — particularly the EU ETS — could unlock demand orders of magnitude larger than the current voluntary market. In the United States, the 45Q tax credit continues to be the primary demand-creation instrument, though policy uncertainty under different administrations adds long-term risk.

Corporate demand through advance purchase agreements and platforms like Frontier is growing, with buyers increasingly differentiating between high-permanence removal (DAC + geological storage) and lower-permanence approaches. By 2030, the carbon removal market could plausibly exceed $10 billion annually if policy frameworks mature and costs continue to decline.

What is the difference between DAC and CCS?

Carbon Capture and Storage (CCS) captures CO₂ at the emission source — a power plant, cement factory, or industrial facility — before it enters the atmosphere. Direct Air Capture (DAC) captures CO₂ already dispersed in the ambient atmosphere, at a concentration of roughly 420 ppm. CCS prevents new emissions; DAC removes existing emissions. CCS is more energy-efficient because it works at higher CO₂ concentrations. DAC is more flexible in siting and is the only engineered option that can address historical atmospheric CO₂ accumulation. Both are components of a net-zero strategy.

Which companies are leading in direct air capture technology?

The leading commercial players as of 2026 are Climeworks (Switzerland, solid sorbent, Mammoth plant in Iceland), 1PointFive / Carbon Engineering (Occidental subsidiary, liquid solvent, Stratos plant in Texas), and Heirloom Carbon (US, accelerated mineralization DAC). Emerging companies include Mission Zero (UK, electrochemical DAC), Carbyon (Netherlands, next-gen sorbents), Skytree (Netherlands, distributed small-scale DAC), and Capture6 (US, Project Octopus, 500 kt/yr). The sector attracted over $650 million in private capital to Climeworks alone in 2022, with continued investment rounds across multiple developers through 2024–2025.

Conclusion: The State of the CDR Scale-Up in 2026

Direct air capture has moved from a speculative climate technology to an operational industry in fewer than five years. The opening of Mammoth in Iceland, the advancement of Stratos in Texas, the disbursement of $1.2 billion in federal US funding, and the adoption of the EU's Carbon Removal Certification Framework — taken together, these represent a structural shift. The conversation has moved from "can this technology work?" to "how fast can it scale, and at what cost?"

The honest verdict is mixed but directionally positive. DAC works. The physics is sound, the chemistry is proven, and the geological storage is real. The challenge is economic: costs remain 4 to 10 times higher than the level needed for broad commercial viability, and the learning curve, while observable, is not running as fast as optimistic models suggested five years ago. Climeworks' own 2024 assessment does not project major cost reductions before 2030 — a sobering data point from the industry leader.

What 2026 has clarified is the market structure. Corporate advance purchases are providing the demand signal. Policy frameworks — particularly the 45Q credit in the US and the CRCF in Europe — are providing the investment certainty. And a growing roster of developers are providing the technological diversity that real markets require. The question is no longer whether this market will exist — it already does — but whether the scale-up can happen fast enough to contribute meaningfully to the 2050 net zero target.

For researchers, policymakers, investors, and business professionals tracking the energy transition, DAC deserves close and continuing attention. It is not the whole solution to climate change. But it is an irreplaceable part of it — and the evidence from the past 24 months suggests it is graduating from demonstration to deployment.
