The Department of Energy's April 18 decision to retain funding for the South Texas DAC Hub and Project Cypress arrived with almost no fanfare, a bureaucratic confirmation that two of the world's largest direct air capture facilities would keep their federal backing. The dollar figure is stark: more than $1 billion in support for 1PointFive's Stratos project in West Texas and Climeworks and Heirloom's Louisiana deployment. For a sector that has lived for two decades in pilot-scale limbo, waiting for one more breakthrough in sorbent chemistry or energy efficiency, this was not a breakthrough announcement. It was something more useful: a signal that carbon removal had crossed from aspirational climate policy into permanent infrastructure.
The backstop is legislative, not rhetorical. 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 DOE selected Project Cypress and the South Texas DAC Hub and disbursed $1.2 billion in initial funding. The uncertainty came later. As the Trump administration took office in January 2025, several major clean energy projects faced review, and for months it remained unclear whether the largest federal carbon removal commitment in U.S. history would survive. The April 18 decision answered that question. These two hubs are now locked in. The funding is real. The timeline is firm.
The scale figures matter because they change what carbon removal means in practice. 1PointFive's Stratos facility is moving toward commissioning at a planned capacity of 500,000 tonnes per year. If that target is achieved, it represents an 873% increase in global direct air capture capacity in a single year. Global operational CO₂ capture and storage capacity currently stands at roughly 50 million tonnes per annum, but that figure includes industrial point-source capture from power plants and refineries. Pure direct air capture, pulling CO₂ from ambient air, stands at a much smaller baseline. Stratos alone would dwarf that installed base. Heirloom is developing two Louisiana facilities with a combined capacity of 320,000 tons per year. Together, these two projects represent 820,000 tonnes per year of new removal capacity entering the market between 2026 and 2028. That is the entire operating carbon removal industry, doubled, in less than three years.
What created the conditions for this funding decision was not a scientific breakthrough, though there have been advances in sorbent architecture and energy efficiency. Rather, it was the voluntary carbon market's credibility collapse. Investigations into nature-based offset projects revealed that many delivered far less removal than claimed, undermining the economics of afforestation, soil carbon, and wetland restoration programs that had dominated the offset landscape. This crisis paradoxically accelerated institutional capital toward direct air capture, which offers three qualities that nature-based offsets struggle with: quantifiability (a sensor confirms how much CO₂ was removed), additionality (you are not just preserving something that would have happened anyway), and permanence (stored CO₂ stays stored). The 45Q tax credit, which pays $180 per tonne for DAC with geological storage through 2026 with inflation adjustments thereafter, provides the floor. But high-integrity carbon credits provide the upside. Institutions that had previously assumed the offset market was solved are now looking at DAC as the only removal technology that withstands third-party scrutiny. The federal government, watching the same credibility erosion, locked this in.
The economics still have not solved. Current cost estimates place removal between $500 and $1,000 per ton of CO₂, depending on technology type, energy sourcing, and storage logistics. The 45Q credit covers $180 per tonne. The gap requires either high-value carbon credits, offtake agreements with corporate buyers willing to pay premium prices for verified removal, or a second revenue stream. That second stream is emerging around synthetic fuels. Captured CO₂ increasingly feeds into sustainable aviation fuel production and synthetic hydrocarbons, which can command prices that improve project economics while solving a genuine supply bottleneck in low-carbon fuels. If 1PointFive or Climeworks can move CO₂ from removal directly into SAF synthesis, the payoff math changes. That possibility is not speculation, both companies are actively negotiating offtake agreements that integrate removal and fuel production.
Who benefits from this decision is clear: 1PointFive, Climeworks, and Heirloom now have unambiguous federal backing to move from construction planning to actual deployment. Engineering firms, compressor manufacturers, pipeline operators, and site developers all have clearer demand signals. Who does not benefit is equally clear: smaller DAC companies that were hoping for a second tranche of federal funding through the remaining two hubs in the original four-hub plan face a much longer timeline. The decision also implicitly supports Texas and Louisiana as the geographic anchors for U.S. carbon removal infrastructure, not California, not the Midwest, not the Northeast. That concentration of federal capital into two regions may accelerate those hubs' deployment but narrows the geographic diversification of the industrial capacity.
The real read: this decision is more significant than it appears because it removes the option value from the narrative. For two years, the sector operated with a latent question: Will federal backing survive a political transition? The answer is yes. That is not because the Trump administration is climate-committed, it is because carbon removal has been successfully reframed as industrial policy and energy security infrastructure, not environmental altruism. DAC feeds into synthetic fuels, which feeds into energy independence, which is a Republican and Democratic priority. The permanent interment of the voluntary carbon market's credibility also means that the only economically viable removal pathway now runs through verified, permanent, geologically stored CO₂, a profile that perfectly matches federal infrastructure investment. The sector will not solve its cost problem in the next eighteen months. But it has solved the political problem. The next inflection point is operational: watch whether Stratos actually achieves its 500,000-tonne-per-year target when it comes online.
Three concrete milestones will tell you whether the funding translates into real capacity. First, 1PointFive's Stratos facility must confirm its commercial commissioning date and demonstrate sustained operation at scale, if the 500,000-tonne capacity target holds, it resets the global conversation about DAC economics. Second, Climeworks and Heirloom must announce formal groundbreaking for the two Louisiana facilities now that federal funding is secure; watch for a 2026 or 2027 start date. Third, California's Energy Commission GFO-25-307 solicitation closes May 29, 2026, the awards will signal which next-generation DAC sorbent and process technologies are moving from lab to pre-commercial pilot. If major technological advances are being deployed in California while Texas ramps manufacturing capacity, the sector is genuinely transitioning from proof-of-concept to industrial deployment.
