Shell DAC Strategy, $17 M Avnos Investment, 1 Houston Pilot, and 2 Key Partnerships (2025)

DAC Project Risk, Shell Navigates Policy Shifts and High Costs

In 2025, Shell is mitigating the extreme risks of the Direct Air Capture (DAC) sector, defined by high costs and policy volatility, by pursuing a dual-track strategy that combines in-house technology validation with targeted investments in a diverse startup portfolio. This approach de-risks its position in a nascent market where technology is unproven and commercial viability is heavily dependent on government subsidies that have proven unreliable.

Shell’s Portfolio Approach to DAC

The company avoids committing to a single technological pathway. Instead, it balances the development of its proprietary solid sorbent technology with venture investments in multiple startups. This contrasts with the period between 2021 and 2024, which was characterized by broader research. The focus in 2025 has sharpened on tangible project development and financial commitments to specific, promising third-party technologies.

• The centerpiece of Shell‘s internal effort is the industrial-scale demonstration unit at the Shell Technology Center Houston, which targets a 2025 start-up to validate its own DAC process.
• Concurrently, Shell acts as a venture catalyst, funding a range of external technologies, including Avnos‘s Hybrid Direct Air Capture (HDAC) and Rep Air Carbon‘s electrochemical system.
• This portfolio strategy provides Shell with exposure to multiple cost-reduction and efficiency pathways, which is critical in a sector where current capture costs of $600-$800 per ton are far from the sub-$200 per ton viability target.

DOE Funding Cancellations Test the Market

The DAC market’s dependence on policy was exposed in October 2025 when the U.S. Department of Energy (DOE) abruptly cancelled funding for 19 of 21 planned DAC hubs. This move terminated over $47.3 million in awards and introduced significant uncertainty for many developers. The strategic importance of being aligned with government priorities became evident from these events.

• The cancellations highlighted the fragility of business models that are heavily reliant on government incentives, a key risk for the entire carbon removal industry.
• Crucially, reports indicated that DOE support was maintained for hubs involving Shell, suggesting its projects and partnerships are perceived as high-quality and strategically aligned with federal decarbonization goals.
• This selective survival reinforces Shell‘s position as a preferred partner and increases the stability of its specific projects relative to the broader market, which now faces a more challenging funding environment.

DAC’s Tiny Share Masks Future Potential Amidst Market Surge
Despite DAC’s current 1% market share in disclosed carbon removal purchases, its presence indicates early-stage investment in crucial, high-permanence removal technologies. The market’s overall 7x growth by 2025 underscores increasing corporate and policy demand, signaling a critical need for diversified portfolio investments beyond dominant BioCCS solutions to achieve long-term net-zero goals.

$23 M in Commitments, Shell Funds a Portfolio of DAC Technologies

Shell‘s 2025 financial commitments, while modest relative to its overall capital expenditure, are highly strategic, aiming to seed a U.S.-based DAC ecosystem and secure access to multiple technology pathways without over-committing capital. These targeted investments, often made in partnership with Mitsubishi Corporation, provide critical early-stage funding to validate promising technologies and build a foundation for future large-scale deployment.

Shell’s Strategic DAC Investments

The company’s investment activity in 2025 is focused on accelerating the commercialization of technologies that promise significant cost and energy reductions. This includes direct project funding and potential offtake agreements, creating vital revenue streams for startups. Unlike other majors such as ADNOC, which has announced a $23 billion budget for decarbonization projects, Shell‘s approach is more selective and focused on technology validation at this stage.

Shell’s 3 Key DAC Alliances with Mitsubishi, Avnos, and Rep Air (2025)

In 2025, Shell consistently leverages partnerships, most notably with Mitsubishi Corporation, to share financial risk, combine industrial expertise, and accelerate the development of its portfolio companies. This collaborative model is fundamental to its strategy, enabling it to participate in more projects and technologies than it could alone and positioning it as a central player in the emerging DAC ecosystem.

The Shell and Mitsubishi Partnership

The alliance with Mitsubishi is a recurring theme in Shell‘s 2025 DAC activities. This partnership combines Shell‘s energy project expertise with Mitsubishi‘s industrial and logistical capabilities, creating a powerful combination for executing complex, first-of-a-kind projects. This strategy of deep collaboration with industrial partners is a consistent part of Shell‘s approach across its new energy ventures, from offshore wind to DAC.

Shell’s Technology-Focused Alliances

Beyond its primary partnership with Mitsubishi, Shell forms direct alliances with technology developers to steer and accelerate their progress. These are not passive investments; they are active collaborations designed to bring promising DAC solutions to market faster. This hands-on approach is also seen with major service companies like SLB, which are increasingly partnering with technology startups to drive innovation.

U.S. Gulf Coast, Shell’s Focus for DAC Hub Development

Shell‘s DAC activities are geographically concentrated in the U.S. Gulf Coast, a strategic decision driven by the lucrative Section 45 Q tax credit, favorable geology for CO 2 storage, and existing industrial infrastructure. This regional focus allows for the creation of integrated hubs that share resources and reduce costs, a model that was largely conceptual between 2021 and 2024 but is now moving into concrete development in 2025.

The Importance of the 45 Q Tax Credit

The commercial case for Shell‘s U.S. projects is underpinned by the Section 45 Q tax credit, which provides $180 per ton for CO 2 captured via DAC and permanently stored. This incentive is currently the most generous of its kind globally and makes the U.S. the most attractive market for early DAC deployment. Without this policy support, none of the announced commercial-scale projects would be economically viable at current technology costs.

Shell’s Pelican Gulf Coast Hub

The development of the Pelican Gulf Coast DAC hub in Louisiana, in partnership with Mitsubishi and Rep Air Carbon, exemplifies Shell‘s regional strategy. The Gulf Coast offers unique advantages, including a skilled workforce, extensive pipeline networks, and well-characterized saline aquifers for permanent CO 2 sequestration. By concentrating its efforts here, Shell can leverage these existing assets to accelerate deployment and create a scalable model for future DAC development.

DAC Technology Validation, Shell’s Houston Demo vs. Startup Plays

Shell‘s 2025 technology strategy is centered on validation, with its proprietary solid sorbent technology moving to an industrial-scale demonstration while its investments target novel, lower-energy approaches. This dual approach acknowledges that while its in-house technology, under development since the 2021-2024 period, is maturing, disruptive innovations from the startup sector could offer superior performance and economics.

Shell’s In-House Solid Sorbent Pilot

The targeted 2025 start-up of the demonstration unit at the Shell Technology Center Houston is a critical milestone. The project’s primary goal is to generate operational data to validate the performance, durability, and cost of Shell‘s proprietary solid sorbent technology at an industrial scale. This data is essential for de-risking future, larger capital commitments and proving the technology’s readiness for commercial deployment.

Evaluating Portfolio Technologies like Avnos

The investment in companies like Avnos represents a hedge against the limitations of Shell‘s internal technology. The Avnos HDAC system is particularly notable because it captures CO 2 and produces water, potentially solving two major operational challenges for DAC: high energy consumption and large water requirements. By funding and helping build the first commercial-scale Avnos facility in 2025, Shell gains direct insight into a potentially superior technological pathway, which it could adopt or integrate in the future.

Shell DAC SWOT Analysis, Strengths in Capital vs Market Headwinds (2025)

Analysis shows Shell‘s strengths lie in its capital access, project execution capabilities, and strategic partnerships, which have allowed it to navigate the volatile 2025 market. However, the company faces significant external threats from potential policy reversals and the immense economic challenge of closing the cost gap for DAC technology, which remains the primary obstacle to widespread adoption.

Table: SWOT Analysis for Shell’s 2025 Direct Air Capture Initiatives

2026 Outlook, Shell’s DAC Execution and Cost Reduction Path

The critical variable for Shell‘s DAC success in 2026 is the performance of its Houston demonstration unit and the ability of portfolio companies like Avnos to hit cost-reduction targets, as policy support alone cannot ensure commercial viability. The operational data from these projects will determine the direction and scale of Shell‘s future capital allocation in the DAC sector.

Watching the Houston Demonstration Unit

If the Houston pilot successfully validates the cost and performance models for Shell‘s solid sorbent technology, watch for the company to announce plans for a larger, commercial-scale plant. This would signal confidence in its proprietary technology and a potential acceleration of its deployment timeline. Failure to meet targets would likely lead to an increased focus on its external portfolio companies.

Monitoring Avnos’s Commercial Progress

If Avnos delivers on its promise of sub-$250 per ton capture costs and co-produces water at its first commercial facility, this could significantly alter Shell‘s long-term technology roadmap. Success could lead to a larger investment or even an acquisition by the Shell–Mitsubishi partnership. These could be happening in parallel with a broader industry pivot toward technologies that address both energy and water constraints, which are becoming key differentiators for DAC viability.
