DAC Project Finance Model, 18, 000 Tonne TD Bank Offtake, $7.2 M Contract, and 3 Deep Sky Agreements (2021 to 2026)

Deep Sky 4 Offtake Agreements Signal Shift to Bankable Carbon Removal (2021 to 2026)

The Direct Air Capture sector is pivoting from a venture-backed technology development phase to a project finance-driven infrastructure build-out, a strategic shift validated by long-term carbon removal offtake agreements. This model, which uses multi-year purchase commitments from creditworthy buyers as a bankable asset, mirrors the Power Purchase Agreement (PPA) playbook that successfully scaled the global wind and solar industries. Recent deals indicate that developers are now focused on building predictable revenue backlogs to de-risk large capital investments and attract non-recourse project debt for first-of-a-kind commercial facilities.

From Venture Capital to Project Finance Models

The period from 2021 to 2024 was defined by technology maturation funded primarily by venture capital and corporate R&D budgets, with a focus on small-scale pilot projects and short-term carbon credit sales. The objective was to prove technological viability at the pilot scale, typically reaching Technology Readiness Level (TRL) 6 or 7. This phase was characterized by high costs and uncertainty over long-term demand, making large-scale project financing inaccessible.

TD Bank’s 18, 000 Tonne Offtake as a De-risking Tool

Beginning in 2025 and accelerating in 2026, the market has seen a decisive shift toward securing long-term, bankable offtake agreements. In June 2026, Deep Sky secured a 10-year agreement with TD Bank Group for over 18, 000 tonnes of verified DAC credits. This commitment, alongside similar deals with Lufthansa Group and technology partner Engie, provides the revenue certainty required to obtain project finance for capital-intensive DAC hubs. The first deliveries of certified credits to Microsoft and RBC in June 2026 serve as a critical proof point of execution capability, further strengthening the case for project lenders.

$7.2 M+ in Contract Value, Deep Sky Validates Offtake-to-Finance Strategy

Multi-year offtake agreements represent a new and critical form of investment in the carbon removal sector, providing the committed revenue streams necessary to unlock significantly larger pools of traditional project finance capital. By securing these contracts, developers like Deep Sky can demonstrate a de-risked financial future to lenders, enabling the transition from pilot projects to commercial-scale infrastructure with debt and equity structures common in mature energy sectors.

TD Bank’s Estimated $7.2 M Contract Value

The financial terms of the TD Bank deal were not disclosed, but its value is substantial. Based on current market prices for high-durability DAC credits, which range from $200 to $800 per tonne, the 10-year Total Contract Value (TCV) can be conservatively estimated at over $7.2 million, assuming a blended price of $400 per tonne. This predictable revenue, backed by a major financial institution, is a cornerstone asset for securing construction financing. The deal is part of a larger pattern of financial validation, including a direct equity investment from Sumitomo Mitsui Banking Corporation (SMBC) in June 2026.

Microsoft Pause Tests Market Resilience

The viability of this model is not without risk, as the voluntary carbon market remains dependent on a small number of large buyers. In April 2026, Microsoft, the world’s largest buyer of carbon removal, announced a temporary pause on new credit purchases, citing high costs and its own rising operational emissions. This event tested market resilience and highlighted the potential for demand-side shocks to disrupt the project finance model. While buyers like TD Bank are stepping in, the market’s long-term stability requires a broader and more diverse customer base.

Partnership Strategy, Deep Sky Aligns with Financial and Industrial Buyers

Deep Sky’s partnership strategy centers on aggregating demand from a diverse portfolio of blue-chip corporate offtakers across multiple sectors, which mitigates reliance on any single buyer and creates a more robust, bankable portfolio. By securing agreements with leaders in finance, aviation, and energy, the company validates its carbon credits as a viable solution for various decarbonization needs, from offsetting residual operational emissions to addressing hard-to-abate sectors.

Financial Sector: TD Bank and RBC

Agreements with financial institutions like TD Bank and RBC are strategically critical. The 18, 000-tonne deal with TD Bank and the first certified credit deliveries to RBC in June 2026 position Deep Sky as a trusted provider for a sector with stringent ESG requirements and a need to address financed emissions. These partnerships not only provide revenue but also lend significant credibility to Deep Sky‘s projects, making them more attractive to other investors and lenders.

Industrial Sector: Lufthansa and Engie

Partnerships with industrial companies target hard-to-abate sectors. The May 2026 agreement with Lufthansa Group provides the airline with a source of high-quality carbon removals to address its emissions, a critical need for the aviation industry. The strategic partnership with global energy firm Engie, announced in April 2026, focuses on developing and optimizing DAC technologies, leveraging Engie’s expertise in large-scale energy project execution to accelerate cost reduction and scalability.

Canada vs. Global DAC Hubs, Deep Sky Leverages Quebec’s Advantages

Canada, specifically the province of Quebec, is rapidly solidifying its position as a leading global hub for DAC development by creating an ecosystem that combines abundant, low-cost renewable energy with favorable geology and supportive government policy. This unique convergence of strategic assets provides a significant competitive advantage for project developers like Deep Sky, enabling them to attract technology partners and capital away from other established and emerging DAC regions.

Quebec’s Strategic Energy and Policy Assets

While global DAC activity between 2021 and 2024 was concentrated in regions like the U.S. Gulf Coast and Iceland, the 2025-2026 period marks the ascent of Quebec as a premier location. The province’s vast supply of low-cost hydropower is a critical enabler for the energy-intensive DAC process. This is complemented by a new provincial law enacted in February 2026 aimed at scaling carbon storage investment, providing the regulatory certainty needed for permanent geological sequestration. This combination reduces both operational costs and project risks.

Canada’s Federal Carbon Management Strategy

At the federal level, Canada’s Carbon Management Strategy, released in January 2026, explicitly identifies carbon management as a critical tool for national decarbonization. This top-down policy support creates a stable and predictable investment climate. The federal Greenhouse Gas Offset Credit System provides a regulated framework for creating and trading carbon credits, ensuring that each credit represents one tonne of verifiably removed CO₂, a key requirement for corporate buyers and project financiers.

Deep Sky’s TRL 6-8 Portfolio Moves to Commercial Scale with Offtake Deals

The DAC sector is navigating the critical transition from pilot-scale validation (TRL 6-7) to first-of-a-kind commercial deployment (TRL 8), a phase often called the “commercial valley of death” for capital-intensive technologies. Long-term offtake agreements, such as the TD Bank deal, provide the crucial demand signal and revenue security needed to bridge this gap, justifying the large-scale capital investment required to build and operate commercial facilities.

The TRL 6 to TRL 8 “Valley of Death”

From 2021 to 2024, the primary focus of DAC companies was demonstrating different technological pathways, including solid sorbent and liquid solvent systems, in pilot environments. While these projects proved the science, they did not demonstrate commercial viability or scalability. The challenge since 2025 has been to secure funding for the first commercial plants, which carry significant construction and operational risks. Offtake agreements directly address the revenue risk, making these projects more palatable to traditional infrastructure investors.

Deep Sky’s Technology-Agnostic Model

Deep Sky’s core strategy is to operate as a technology-agnostic project developer, which diversifies technological risk. Instead of betting on a single DAC method, it partners with multiple technology providers, such as Air Capture and others, to test and deploy a portfolio of solutions at its Canadian hubs. This approach is attractive to credit buyers like TD Bank, who are purchasing guaranteed carbon removal, not a specific technology. The delivery of certified credits in June 2026 serves as tangible proof that this integrated model can successfully move technologies from pilot to commercial delivery.

SWOT Analysis, Deep Sky’s Bankable Model and Market Headwinds

Deep Sky’s strategic position is defined by its innovative offtake-to-project-finance model and prime geographic location, but its success is contingent on navigating significant technology scaling challenges and market volatility. The company’s ability to execute on its project pipeline while the market for high-durability credits matures will determine its long-term leadership in the DAC sector.

Scenario Modelling, Deep Sky’s Next Test is Securing Project Finance

The most critical forward-looking catalyst for Deep Sky and the broader DAC sector is the announcement of a Final Investment Decision (FID) on a large-scale commercial facility, backed by traditional project finance. Such an event would serve as the ultimate validation that the offtake-to-finance model has successfully unlocked the infrastructure-level capital required to build the industry. The next 12-18 months will be decisive.

The Final Investment Decision (FID) Catalyst

If Deep Sky announces it has secured project-level debt and equity for its first commercial facility, such as its planned 500, 000-tonne-per-year project, watch for details on the lenders and equity partners involved. An FID would signal that financial institutions view the technology and revenue risks as manageable, setting a powerful precedent for the entire sector. This would likely trigger a new wave of capital into competing DAC projects from developers like Climeworks and Carbon Engineering, who would be pressured to secure similar financing structures.

Monitoring Cost-per-Tonne Performance

Upon commissioning its first large-scale plants, the key signal to monitor will be the release of independently verified data on the all-in cost per tonne of CO₂ removed and sequestered. A critical inflection point will be achieving costs at or below the company’s sub-$500/tonne target for its Alpha project, with a clear and credible roadmap toward sub-$200/tonne. Failure to demonstrate a downward cost trajectory could undermine confidence in future projects and slow the flow of capital into the sector.
