DAC Aviation Offtakes, 400, 000 Tonne Airbus Deal, 2.9 M Tonne Demand, and the $180/ton 45 Q Credit (2021 to 2026)

DAC Commercial Scale, Climeworks and 1 Point Five lead Aviation Offtakes

The Direct Air Capture industry is shifting from a speculative technology to a bankable asset class, a transition driven by large-scale, long-term offtake agreements from the aviation sector. This commercial evolution converts future carbon removal into a financeable instrument, underpinning the project economics required to build megaton-scale facilities. The primary risk is evolving from technological feasibility to execution, cost control, and policy stability.

• Between 2021 and 2024, the market was defined by smaller, technology-led pre-purchase agreements from companies like Microsoft, which established the initial price signals for high-durability credits. The 2022 letter of intent from an Airbus-led airline consortium to pre-purchase 400, 000 metric tons from 1 Point Five was a foundational signal of aviation’s strategic interest, even as total operational DAC capacity remained below 0.01 million tonnes annually.
• From 2025 to today, this model has matured with direct airline offtake agreements, including Lufthansa Group’s deal with Deep Sky in May 2026. Corporate-led demand for DAC credits reached approximately 2.9 million tonnes, creating a tangible demand signal that enables developers to secure project financing.
• The risk profile has shifted from proving the technology to proving commercial scalability and bankability. The late 2025 political uncertainty surrounding the U.S. Department of Energy’s DAC Hubs, which threatened billions in funding for projects involving Climeworks and Heirloom, highlights the sector’s acute exposure to policy risk.
• While aviation is a key anchor for permanent removal credits, the revenue model is diversifying. Other industrial and energy companies like Schneider Electric and ENGIE are also signing offtake agreements, creating a broader base of demand that validates the technology’s role across multiple decarbonization strategies.

Investment Volatility, 1 Point Five and the DOE’s DAC Hub Funding Shifts

Direct Air Capture investment is characterized by a dual reliance on large, policy-backed funding mechanisms and concentrated private capital, creating a volatile but ultimately upward funding trajectory. The sector’s financial health is directly tied to the stability of public incentives, which act as the primary de-risking agent for attracting the large-scale project finance needed to move from pilot to commercial scale.

• Venture and growth investment in carbon capture and removal showed significant volatility, peaking at over $2.2 billion in 2022 before contracting to less than $1 billion by 2025. This indicates a market maturation, shifting from early-stage venture funding to a more demanding project finance environment where bankable offtake agreements are essential.
• The U.S. Department of Energy’s DAC Hub program represents the most significant public investment driver. The announcement in late 2025 to potentially cancel funding for several hubs exposed the sector’s vulnerability to political shifts and created significant uncertainty for major players like Climeworks, Heirloom, and 1 Point Five.
• The subsequent preservation of federal funding for key U.S. DAC and hydrogen hubs in April 2026 provided critical stability and reaffirmed the technology’s strategic importance. However, the event underscored that policy risk remains a primary concern for investors and developers.
• The U.S. Section 45 Q tax credit, enhanced by the Inflation Reduction Act to $180 per ton for permanent storage, functions as a government-backed revenue floor. This incentive is the critical component that makes U.S.-based DAC projects bankable, directly enabling the offtake agreement model.

Climeworks 2 Key Offtake Agreements for DAC (2025 to 2026)

Long-term offtake agreements from diverse, creditworthy buyers are the primary commercial mechanism transforming future carbon removal into a present, bankable asset. These contracts provide the revenue certainty required for developers to secure financing for capital-intensive DAC facilities, effectively bridging the gap between high upfront costs and future value.

• The aviation industry has solidified its role as a key anchor customer for DAC credits. The Lufthansa Group’s agreement with Deep Sky in May 2026 is a recent example of this trend, building on the precedent set by the 2022 Letter of Intent from an Airbus-led consortium for 1 Point Five’s credits.
• Demand is diversifying beyond aviation, with technology and industrial companies providing critical early adoption. Schneider Electric’s September 2025 agreement with Climeworks to remove 31, 000 tons of CO₂ demonstrates the broadening appeal of high-durability removals.
• Partnerships are evolving beyond simple credit transactions to include deeper strategic alignment. The April 2026 deal between ENGIE and Deep Sky combines credit procurement with joint research and market development, signaling a commitment to building the broader carbon removal ecosystem.
• The scale and duration of these agreements are increasing, providing greater financial certainty. Microsoft’s landmark 2023 agreement to purchase up to 315, 000 metric tons of CO₂ removal from Heirloom set a benchmark for large-volume, multi-year deals that the market is now emulating.

US Policy Focus, 1 Point Five and the 45 Q Tax Credit

The United States dominates global Direct Air Capture project development and investment due to the unparalleled financial incentives provided by the Inflation Reduction Act’s Section 45 Q tax credit. This policy has effectively concentrated large-scale commercial activity within the U.S., making it the most commercially attractive region for building and operating DAC facilities.

• In the 2021-2024 period, DAC development was more geographically dispersed, with pioneers like Climeworks establishing initial projects in Europe, such as its Orca plant in Iceland. The U.S. had active projects, but its policy incentives were not yet the primary global driver.
• From 2025 onward, the U.S. has become the clear epicenter for large-scale DAC deployment. The enhanced 45 Q tax credit, offering $180 per ton for permanently stored CO₂, creates a decisive economic advantage. Major projects, such as 1 Point Five’s Stratos facility in Texas, are a direct result of this policy.
• The DOE’s DAC Hub program further concentrates activity in the U.S. Gulf Coast, targeting locations in Texas and Louisiana that offer advantageous geological storage formations and existing energy infrastructure.
• While other regions remain active, they lack a comparable financial pull. Canada is fostering a growing hub with companies like Deep Sky, and Europe continues to host important research and pilot facilities. However, large-scale commercial deployments are overwhelmingly targeting the robust economic case presented by U.S. policy.

Government Policy and Corporate Action Drive DAC Market

$600/ton Costs, Climeworks and the DAC Scale-up Challenge

While technologically proven at a pilot scale, Direct Air Capture’s commercial maturity is constrained by high operational and capital costs. The industry’s viability and ability to attract investment depend entirely on executing a steep and credible cost-reduction curve, transitioning the technology from a subsidized niche to a competitive market solution.

• Between 2021 and 2024, the primary technical focus was on validating different technology pathways, such as solid sorbent and liquid solvent systems, and achieving operational stability for first-of-a-kind plants. During this phase, costs were frequently cited in the $600 to $1, 000 per ton range.
• From 2025 to today, the technology has matured to the point where developers are planning megaton-scale facilities. However, costs remain the primary commercial barrier, with 2026 estimates still spanning a wide range of $250 to $1, 000 per ton depending on the technology and project maturity.
• The industry’s business model is predicated on aggressive cost-reduction targets. Climeworks, a market leader, announced plans to halve its costs by 2030. The credibility of these projected cost-down curves is a critical factor for securing long-term offtake agreements and project financing.
• The market for delivered credits is highly concentrated. As of late 2025, just three companies, Climeworks, 1 Point Five, and Heirloom, accounted for 80% of all DAC credits sold. This indicates that very few developers have reached a level of technological maturity sufficient for large-scale commercial contracts, posing a systemic supply-side risk.

SWOT Analysis, Climeworks and DAC Market Dependencies

The Direct Air Capture industry’s primary strength is its ability to provide high-durability, verifiable carbon removals, an asset increasingly valued by corporate offtakers. This strength is counterbalanced by significant weaknesses in cost and scale, with opportunities in policy and new markets threatened by execution risk and potential shifts in corporate climate ambition.

• The core value proposition of DAC, its permanence, has been validated through premium pricing on the voluntary market and large-scale offtake agreements from sectors like aviation.
• The industry’s reliance on a few key technologies and developers, coupled with persistent high costs and uncertain cost-down trajectories, creates significant commercial and operational fragility.
• Unprecedented policy support in the U.S. (45 Q) and growing demand from hard-to-abate sectors represent the most powerful growth drivers, creating a clear opportunity for first-movers.
• The sector remains highly vulnerable to shifts in political priorities, as seen in the 2025 funding uncertainty, as well as the risk of failing to deliver complex, first-of-a-kind industrial projects on time and on budget.

1 Point Five 2026 Offtake and DAC Project Finance Scenarios

The critical factor for the Direct Air Capture industry in the next 12-24 months is the successful financial close and construction start of the next wave of large-scale plants. This step will serve as the ultimate validation of the aviation offtake model’s bankability and determine the sector’s near-term growth trajectory.

• If this happens: Leading DAC developers like 1 Point Five, Climeworks, and Heirloom successfully leverage their portfolios of offtake agreements to secure non-dilutive project financing for their next major facilities, proving the model works.
• Watch this: The announcement of a final investment decision (FID) for a large-scale DAC plant that explicitly cites aviation offtake agreements as a cornerstone of its financing package. Also, monitor the price, volume, and duration of new offtake deals to gauge the health of market demand.
• These could be happening: Financial institutions begin to standardize terms and develop new products for carbon removal projects, treating offtake agreements as a distinct asset class. More airlines, particularly outside the initial group of first movers, start signing their own offtake deals, broadening the demand base and creating a more liquid market.
