Direct Air Capture (DAC) technology has emerged as one of the most promising yet challenging tools in the fight against climate change. By extracting carbon dioxide directly from the atmosphere, DAC offers the potential to address residual emissions and even draw down historical carbon. Over the past few years, global attention has surged, driven by both the urgency of the climate crisis and the commitments of major corporations to achieve net-zero targets. Companies like Microsoft, Stripe, and Occidental have been early adopters, committing substantial funds to scale up DAC.
However, despite its promise, DAC remains a niche technology accessible mainly to organizations with deep pockets. Rather than being simply a matter of exclusivity, the situation reflects underlying economic realities, market dynamics, and the current stage of technological maturity. Understanding why DAC is currently the playground of the biggest players helps illuminate the pathways to broader participation.
The most obvious reason large corporations lead in DAC deployment is the high upfront capital cost. Building a commercial-scale DAC facility can require hundreds of millions of dollars in investment, often before any clear path to profitability is established. While costs per ton of CO₂ removed vary by technology, they typically range between $600 and $1,000 per ton, a level far above what most small or mid-sized companies can afford.
DAC is also still in its early commercialization stage, meaning unit costs have not yet benefitted from widespread economies of scale. Market demand for high-cost carbon removal credits remains limited, with the voluntary carbon market dominated by corporates willing to pay premium prices for high-quality removals to meet their climate commitments.
Adding to this challenge is the long payback period. Investments in DAC are made with the expectation that learning curves, technological improvements, and supportive policy will eventually reduce costs. But that future may be a decade or more away making such commitments risky for smaller players.
Large corporations possess a set of structural advantages that position them well to invest in DAC despite the risks. Access to capital is the most obvious: major corporations can allocate hundreds of millions to climate technology without endangering their core operations.
These firms also derive brand and ESG value from being early movers. High-profile DAC investments signal leadership in climate responsibility, enhancing reputation among stakeholders, customers, and investors.
Importantly, large companies have a higher risk tolerance. They can absorb potential technological setbacks or delays without jeopardizing their financial stability. Furthermore, they benefit from strong partnership networks, which allow them to collaborate with technology developers, governments, and financiers to de-risk projects.
Despite current barriers, several trends suggest DAC could become more accessible to smaller organizations in the coming decade. Policy support is a major driver: in the U.S., the expanded 45Q tax credit offers up to $180 per ton for CO₂ captured and stored, while the EU is developing frameworks to certify and trade carbon removal credits.
Technological innovation is also reshaping the economics. Modular DAC units, which are smaller and standardized systems, allow for incremental scaling and faster learning curves. Advances in sorbent materials and process optimization promise lower operational costs.
New aggregation models are emerging, enabling smaller buyers to pool funds to purchase DAC credits collectively. Innovative financing mechanisms, such as blended finance and dedicated climate funds, are helping bridge the gap for non-mega-corporates. Finally, regional DAC hubs, where capture facilities share infrastructure for CO₂ transport and storage, could significantly reduce individual project costs.
Today, DAC remains an expensive, capital-intensive climate solution naturally suited to large corporations with the resources to invest early. However, cost curves are bending downward, policy incentives are growing stronger, and collaborative financing models are emerging. These shifts could, over time, open the door for municipalities, SMEs, and community organizations to participate in meaningful carbon removal.
If technological innovation and supportive policy continue on their current trajectory, DAC could transition from an exclusive tool for corporate giants into a mainstream instrument for climate action, deployed widely, financed creatively, and embraced across sectors.
