Heirloom Is Moving a Giant DAC Project to Shreveport

We have questions.

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.

Why Shreveport?

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.”

Will this make Project Cypress more expensive?

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.”

Did the Department of Energy approve the change?

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.

Wind Is More Powerful Than J. D. Vance Seems to Think

It’s a good thing most of us aren’t accountable for every single silly thing we’ve ever said, but most of us are not vice presidential running mates, either. Back in 2022, when J.D. Vance was still just a “New York Times bestselling author” and not yet a “junior senator from Ohio,” much less “second-in-line to a former president who will turn 80 in office if he’s reelected,” he made a climate oopsie that — now that it’s recirculating — deserves to be addressed.

If Democrats “care so much about climate change,” Vance argued during an Ohio Republican senator candidate forum during that year, “and they think climate change is caused by carbon emissions, then why is their solution to scream about it at the top of their lungs, send a bunch of our jobs to China, and then manufacture these ridiculous ugly windmills all over Ohio farms that don’t produce enough electricity to run a cell phone?”

The United Nations calls 24/7 carbon-free energy generation, also known as hourly matching, “the end state of a fully decarbonized electricity system.” It means that every kilowatt-hour of electricity consumed is matched with a zero-emissions electricity source, every hour of every day. It’s something that Google and Microsoft are aiming to implement by 2030, and it represents a much more significant climate commitment than today’s default system of annualized matching

So here’s a positive sign: LevelTen Energy, the leading marketplace for power purchase agreements, just raised $65 million in Series D funding, led by the investment firm B Capital with participation from Microsoft, Google, and Prelude Ventures, among others.

Beryl making landfall in Texas.

Hurricane Beryl, ahem, barreled into America’s Gulf Coast as a Category 1 storm, and whenever something like that happens the entire global energy industry holds its breath. The Gulf of Mexico is not just a frequent target and breeding ground for massive storms, it is also one of America’s — and the world’s — most important energy hubs. Texas and Louisiana contains giant oil and gas fields, and the region is home to about half of the United States’ refining capacity.

At least so far, the oil and refining industry appears to have largely dodged Beryl’s worst effects. The storm made landfall in Matagorda, a coastal town between Galveston and Corpus Christi, both of which are major centers for the refinery industry. Only one refinery, the Phillips 66 facility in Sweeny, Texas, was in the storm’s cone, according to TACenergy, a petroleum products distributor. Phillips 66 did not respond to a request to comment, but Reuters reported that the Sweeny facility as well as its refinery in Lake Charles, Louisiana were powered and operating. Crude oil prices have seen next to no obvious volatility, rising to $83.88 a barrel on July 3 and since settling around $82.84.
