Who thought that was a good idea?

Not a promising start to summer for urban emergency planners.
Northwest Louisiana is about to be awash in direct air capture. Heirloom announced today that it’s moving its half of the Department of Energy-funded Project Cypress DAC hub from coastal Calcasieu Parish inland to Shreveport — and that it will be building a second facility, capable of removing 17,000 metric tons of carbon dioxide annually, on the same site. Once the two facilities reach full scale, they will have the capacity to suck up a combined 317,000 metric tons of CO2 per year.
Project Cypress, one of two regional DAC hubs that’s been announced thus far, is a partnership between Bay Area-based Heirloom, the Swiss DAC company Climeworks, and project developer Battelle. As per the initial plan, Climeworks will still build out its portion of Project Cypress in southwest Louisiana, and together with Heirloom’s Shreveport plant, the two facilities will pull a combined megaton of CO2 out of the atmosphere every year.
Those are the basic facts, but still, I had a lot of questions. Why make the move at all? What does it mean for Project Cypress, for the Calcasieu community, and for Climeworks? Here’s what Heirloom told me.
Heirloom was already in the planning phase for its 17,000 ton facility in Shreveport prior to its selection for the DAC hubs program, a spokesperson told me. Thus, “it became clear that co-locating our portion of the Project Cypress Hub in the same location made a lot of sense from a cost and operational efficiency perspective.”
At this early stage it’s hard to say. But Heirloom and Climeworks will now need to develop their own distinct CO2 transport and storage systems, infrastructure that could have been shared were the two facilities close together.
Heirloom, for its part, expects its new 17,000 ton facility to be operational by 2026, while its larger Project Cypress plant is planned to come online in 2027. Initially, this larger facility will remove 100,000 metric tons of CO2 annually, eventually ramping up to 300,000 metric tons. For both projects, Heirloom is partnering with the carbon management company CapturePoint to permanently sequester CO2 in underground wells.
But storing carbon is not the only logistical challenge involved. The companies will now need to undertake separate community planning and engagement processes, a daunting task even when they had just one to figure out. And yet, the Heirloom spokesperson told us, because planning for Project Cypress is still in its early stages, any additional impacts will be “minimal.”
The DOE administers the DAC Hub program that awarded Project Cypress $50 million in March, so this is no small question. The program is “meant to spur the development of clean energy capabilities across geographical regions, not necessarily in one specific location,” the Heirloom spokesperson told me, and said “the Department of Energy has been incredibly supportive of Heirloom’s expansion into North West Louisiana.” (When we asked DOE, a representative said the agency knew of the move but didn’t provide any further details.)
All this comes on the heels of a big year for Heirloom, which uses limestone powder to absorb CO2 from the atmosphere. Late last year it unveiled its first commercial DAC facility, which is capable of capturing 1,000 metric tons annually. The Shreveport plants thus represent a massive scale-up.
Heirloom wouldn’t disclose its cost per metric ton of CO2 removed, but the spokesperson said it’s currently “in the high hundreds of dollars,” and that it has an eye toward getting below $100 per metric ton by 2035, the widely accepted metric for commercial viability. So far, the company said, it has “sold a substantial portion of the capacity from both facilities to voluntary buyers.” Customers include major players in the voluntary carbon removal market, including Microsoft, Stripe, Klarna, JPMorgan Chase and Meta. Louisiana is also providing Heirloom with a set of economic incentives worth around $10 million, the company said.

Environmentalists, however, still aren’t sold on the ADVANCE Act.
While climate change policy is typically heavily polarized along party lines, nuclear energy policy is not. The ADVANCE Act, which would reform the nuclear regulatory policy to encourage the development of advanced nuclear reactors, passed the Senate today, by a vote of 88-2, preparing it for an almost certain presidential signature.
The bill has been floating around Congress for about a year and is the product of bipartisanship within the relevant committees, a notable departure from increasingly top-down legislating in Washington. The House of Representatives has its own nuclear regulatory bill, the Atomic Energy Advancement Act, which the House overwhelmingly voted for in February.
The resulting bill — a.k.a. the one that just passed — is a compromise between the House bill and the ADVANCE Act originally introduced in 2023, has been stapled to the “Fire Grants and Safety Act,” a bipartisan bill that reauthorizes a gaggle of federal firefighting programs that has already passed the House.
The nuclear piece of it is designed to align the Nuclear Regulatory Commission around so-called “advanced” nuclear reactors, a catch-all term that covers a number of designs and concepts that are typically smaller than the existing light water reactor fleet and would, ideally, be largely factory-built to reduce costs. So far, the NRC has only approved one advanced reactor design, put forward by the nuclear startup NuScale, but plans to actually build it fell through due to escalating costs. Another advanced nuclear project, Bill-Gates-backed TerraPower, has started construction ahead of receiving approval from the NRC.
The ADVANCE Act would eliminate some fees for applicants going through the NRC approval process; instruct the NRC to develop specific rules for “microreactors,” which might only have 20 or so megawatts of capacity and could be used for single sites or rural areas; establish prizes for advanced reactors; and “streamline” the NRC process for advanced nuclear reactors. That last bit would involve beefing up the Commission with additional staffing, change its mission statement to be more supportive of nuclear energy’s benefits (as opposed to merely its risks), and come up with a way to make it easier to develop nuclear reactors on brownfield sites such as decommissioned coal plants.
The Nuclear Energy Institute said in a statement in April that the bill would “improve our ability to get more nuclear reactors approved and on the grid more quickly.” That is exactly what some environmental groups are unhappy about, however. “Senate Majority Leader Chuck Schumer’s apparent embrace of new nuclear energy development represents a stark betrayal of the clean, safe renewable energy options like wind and solar that he claims to champion,” Wenonah Hauter, executive director of Food & Water Watch, said in a statement last week.
The ADVANCE Act is just one of a flurry of legislative and executive actions to support the nuclear energy industry. Nuclear power qualifies for a number of Inflation Reduction Act tax credits and the beefed up Loan Programs Office has committed up to $1.5 billion for the re-opening of the Palisades Nuclear Plant in Michigan.
