Inside Climeworks’ big experiment to wrest carbon from the air
In the spring of 2021, the world’s leading authority on energy published a “roadmap” for preventing the most catastrophic climate change scenarios. One of its conclusions was particularly daunting. Getting energy-related emissions down to net zero by 2050, the International Energy Agency said, would require “huge leaps in innovation.”
Existing technologies would be mostly sufficient to carry us down the carbon curve over the next decade. But after that, nearly half of the remaining work would have to come from solutions that, for all intents and purposes, did not exist yet. Some would only require retooling existing industries, like developing electric long-haul trucks and carbon-free steel. But others would have to be built from almost nothing and brought to market in record time.
What will it take to rapidly develop new solutions, especially those that involve costly physical infrastructure and which have essentially no commercial value today?
That’s the challenge facing Climeworks, the Swiss company developing machines to wrest carbon dioxide molecules directly from the air. In September 2021, a few months after the IEA’s landmark report came out, Climeworks switched on its first commercial-scale “direct air capture” facility, a feat of engineering it dubbed “Orca,” in Iceland.
The technology behind Orca is one of the top candidates to clean up the carbon already blanketing the Earth. It could also be used to balance out any stubborn, residual sources of greenhouse gases in the future, such as from agriculture or air travel, providing the “net” in net-zero. If we manage to scale up technologies like Orca to the point where we remove more carbon than we release, we could even begin cooling the planet.
As the largest carbon removal plant operating in the world, Orca is either trivial or one of the most important climate projects built in the last decade, depending on how you look at it. It was designed to capture approximately 4,000 metric tons of carbon from the air per year, which, as one climate scientist, David Ho, put it, is the equivalent of rolling back the clock on just 3 seconds of global emissions. But the learnings gleaned from Orca could surpass any quantitative assessment of its impact. How well do these “direct air capture” machines work in the real world? How much does it really cost to run them? And can they get better?
The company — and its funders — are betting they can. Climeworks has made major deals with banks, insurers, and other companies trying to go green to eventually remove carbon from the atmosphere on their behalf. Last year, the company raised $650 million in equity that will “unlock the next phase of its growth,” scaling the technology “up to multi-million-ton capacity … as carbon removal becomes a trillion-dollar market.” And just last month, the U.S. Department of Energy selected Climeworks, along with another carbon removal company, Heirloom, to receive up to $600 million to build a direct air capture “hub” in Louisiana, with the goal of removing one million tons of carbon annually.
Two years after powering up Orca, Climeworks has yet to reveal how effective the technology has proven to be. But in extensive interviews, top executives painted a picture of innovation in progress.
Chief marketing officer Julie Gosalvez told me that Orca is small and climatically insignificant on purpose. The goal is not to make a dent in climate change — yet — but to maximize learning at minimal cost. “You want to learn when you're small, right?” Gosalvez said. “It’s really de-risking the technology. It’s not like Tesla doing EVs when we have been building cars for 70 years and the margin of learning and risk is much smaller. It’s completely new.”
From the ground, Orca looks sort of like a warehouse or a server farm with a massive air conditioning system out back. The plant consists of eight shipping container-sized boxes arranged in a U-shape around a central building, each one equipped with an array of fans. When the plant is running, which is more or less all the time, the fans suck air into the containers where it makes contact with a porous filter known as a “sorbent” which attracts CO2 molecules.

When the filters become totally saturated with CO2, the vents on the containers snap shut, and the containers are heated to more than 212 degrees Fahrenheit. This releases the CO2, which is then delivered through a pipe to a secondary process called “liquefaction,” where it is compressed into a liquid. Finally, the liquid CO2 is piped into basalt rock formations underground, where it slowly mineralizes into stone. The process requires a little bit of electricity and a lot of heat, all of which comes from a carbon-free source — a geothermal power plant nearby.
A day at Orca begins with the morning huddle. The total number on the team is often in flux, but it typically has a staff of about 15 people, Climeworks’ head of operations Benjamin Keusch told me. Ten work in a virtual control room 1,600 miles away in Zurich, taking turns monitoring the plant on a laptop and managing its operations remotely. The remainder work on site, taking orders from the control room, repairing equipment, and helping to run tests.
During the huddle, the team discusses any maintenance that needs to be done. If there’s an issue, the control room will shut down part of the plant while the on-site workers investigate. So far, they’ve dealt with snow piling up around the plant that had to be shoveled, broken and corroded equipment that had to be replaced, and sediment build-up that had to be removed.

The air is more humid and sulfurous at the site in Iceland than in Switzerland, where Climeworks had built an earlier, smaller-scale model, so the team is also learning how to optimize the technology for different weather. Within all this troubleshooting, there’s additional trade-offs to explore and lessons to learn. If a part keeps breaking, does it make more sense to plan to replace it periodically, or to redesign it? How do supply chain constraints play into that calculus?
The company is also performing tests regularly, said Keusch. For example, the team has tested new component designs at Orca that it now plans to incorporate into Climeworks’ next project from the start. (Last year, the company began construction on “Mammoth,” a new plant that will be nine times larger than Orca, on a neighboring site.) At a summit that Climeworks hosted in June, co-founder Jan Wurzbacher said the company believes that over the next decade, it will be able to make its direct air capture system twice as small and cut its energy consumption in half.
“In innovation lingo, the jargon is we haven’t converged on a dominant design,” Gregory Nemet, a professor at the University of Wisconsin who studies technological development, told me. For example, in the wind industry, turbines with three blades, upwind design, and a horizontal axis, are now standard. “There were lots of other experiments before that convergence happened in the late 1980s,” he said. “So that’s kind of where we are with direct air capture. There’s lots of different ways that are being tried right now, even within a company like Climeworks."
Although Climeworks was willing to tell me about the goings-on at Orca over the last two years, the company declined to share how much carbon it has captured or how much energy, on average, the process has used.
Gosalvez told me that the plant’s performance has improved month after month, and that more detailed information was shared with investors. But she was hesitant to make the data public, concerned that it could be misinterpreted, because tests and maintenance at Orca require the plant to shut down regularly.
“Expectations are not in line with the stage of the technology development we are at. People expect this to be turnkey,” she said. “What does success look like? Is it the absolute numbers, or the learnings and ability to scale?”
Danny Cullenward, a climate economist and consultant who has studied the integrity of various carbon removal methods, did not find the company’s reluctance to share data especially concerning. “For these earliest demonstration facilities, you might expect people to hit roadblocks or to have to shut the plant down for a couple of weeks, or do all sorts of things that are going to make it hard to transparently report the efficiency of your process, the number of tons you’re getting at different times,” he told me.
But he acknowledged that there was an inherent tension to the stance, because ultimately, Climeworks’ business model — and the technology’s effectiveness as a climate solution — depend entirely on the ability to make precise, transparent, carbon accounting claims.
Nemet was also of two minds about it. Carbon removal needs to go from almost nothing today to something like a billion tons of carbon removed per year in just three decades, he said. That’s a pace on the upper end of what’s been observed historically with other technologies, like solar panels. So it’s important to understand whether Climeworks’ tech has any chance of meeting the moment. Especially since the company faces competition from a number of others developing direct air capture technologies, like Heirloom and Occidental Petroleum, that may be able to do it cheaper, or faster.
However, Nemet was also sympathetic to the position the company was in. “It’s relatively incremental how these technologies develop,” he said. “I have heard this criticism that this is not a real technology because we haven’t built it at scale, so we shouldn’t depend on it. Or that one of these plants not doing the removal that it said it would do shows that it doesn’t work and that we therefore shouldn’t plan on having it available. To me, that’s a pretty high bar to cross with a climate mitigation technology that could be really useful.”
More data on Orca is coming. Climeworks recently announced that it will work with the company Puro.Earth to certify every ton of CO2 that it removes from the atmosphere and stores underground, in order to sell carbon credits based on this service. The credits will be listed on a public registry.
But even if Orca eventually runs at full capacity, Climeworks will never be able to sell 4,000 carbon credits per year from the plant. Gosalvez clarified that 4,000 tons is the amount of carbon the plant is designed to suck up annually, but the more important number is the amount of “net” carbon removal it can produce. “That might be the first bit of education you need to get out there,” she said, “because it really invites everyone to look at what are the key drivers to be paid attention to.”
She walked me through a chart that illustrated the various ways in which some of Orca’s potential to remove carbon can be lost. First, there’s the question of availability — how often does the plant have to shut down due to maintenance or power shortages? Climeworks aims to limit those losses to 10%. Next, there’s the recovery stage, where the CO2 is separated from the sorbent, purified, and liquified. Gosalvez said it’s basically impossible to do this without losing some CO2. At best, the company hopes to limit that to 5%.
Finally, the company also takes into account “gray emissions,” or the carbon footprint associated with the business, like the materials, the construction, and the eventual decommissioning of the plant and restoration of the site to its former state. If one of Climeworks’ plants ever uses energy from fossil fuels (which the company has said it does not plan to do) it would incorporate any emissions from that energy. Climeworks aims to limit gray emissions to 15%.
In the end, Orca’s net annual carbon removal capacity — the amount Climeworks can sell to customers — is really closer to 3,000 tons. Gosalvez hopes other carbon removal companies adopt the same approach. “Ultimately what counts is your net impact on the planet and the atmosphere,” she said.

Despite being a first-of-its-kind demonstration plant — and an active research site — Orca is also a commercial project. In fact, Gosalvez told me that Orca’s entire estimated capacity for carbon removal, over the 12 years that the plant is expected to run, sold out shortly after it began operating. The company is now selling carbon removal services from its yet-to-be-built Mammoth plant.
In January, Climeworks announced that Orca had officially fulfilled orders from Microsoft, Stripe, and Shopify. Those companies have collectively asked Climeworks to remove more than 16,000 tons of carbon, according to the deal-tracking site cdr.fyi, but it’s unclear what portion of that was delivered. The achievement was verified by a third party, but the total amount removed was not made public.
Climeworks has also not disclosed how much it has charged companies per ton of carbon, a metric that will eventually be an important indicator of whether the technology can scale to a climate-relevant level. But it has provided rough estimates of how much it expects each ton of carbon removal to cost as the technology scales — expectations which seem to have shifted after two years of operating Orca.
In 2021, Climeworks co-founder Jan Wurzbacher said the company aimed to get the cost down to $200 to $300 per ton removed by the end of the decade, with steeper declines in subsequent years. But at the summit in June, he presented a new cost curve chart showing that the price was currently more than $1,000, and that by the end of the decade, it would fall to somewhere between $400 to $700. The range was so large because the cost of labor, energy, and storing the CO2 varied widely by location, he said. The company aims to get the price down to $100 to $300 per ton by 2050, when the technology has significantly matured.
Critics of carbon removal technologies often point to the vast sums flowing into direct air capture tech like Orca, which are unlikely to make a meaningful difference in climate change for decades to come. During a time when worsening disasters make action feel increasingly urgent, many are skeptical of the value of investing limited funds and political energy into these future solutions. Carbon removal won’t make much of a difference if the world doesn’t deploy the tools already available to reduce emissions as rapidly as possible — and there’s certainly not enough money or effort going into that yet.
But we’ll never have the option to fully halt climate change, let alone begin reversing it, if we don’t develop solutions like Orca. In September, the International Energy Agency released an update to its seminal net-zero report. The new analysis said that in the last two years, the world had, in fact, made significant progress on innovation. Now, some 65% of emission reductions after 2030 could be accounted for with technologies that had reached market uptake. It even included a line about the launch of Orca, noting that Climeworks’ direct air capture technology had moved from the prototype to the demonstration stage.
But it cautioned that DAC needs “to be scaled up dramatically to play the role envisaged,” in the net zero scenario. Climeworks’ experience with Orca offers a glimpse of how much work is yet to be done.

Current conditions: In the Atlantic, the tropical storm that could, as it develops, take the name Jerry is making its way westward toward the U.S. • In the Pacific, Hurricane Priscilla strengthened into a Category 2 storm en route to Arizona and the Southwest • China broke an October temperature record with thermometers surging near 104 degrees Fahrenheit in the southeastern province of Fujian.
The Department of Energy appears poised to revoke awards to two major Direct Air Capture Hubs funded by the Infrastructure Investment and Jobs Act in Louisiana and Texas, Heatmap’s Emily Pontecorvo reported Tuesday. She got her hands on an internal agency project list that designated nearly $24 billion worth of grants as “terminated,” including Occidental Petroleum’s South Texas DAC Hub and Louisiana's Project Cypress, a joint venture between the DAC startups Heirloom and Climeworks. An Energy Department spokesperson told Emily that he was “unable to verify” the list of canceled grants and said that “no further determinations have been made at this time other than those previously announced,”referring to the canceled grants the department announced last week. Christoph Gebald, the CEO of Climeworks, acknowledged “market rumors” in an email, but said that the company is “prepared for all scenarios.” Heirloom’s head of policy, Vikrum Aiyer, said the company wasn’t aware of any decision the Energy Department had yet made.
While the list floated last week showed the Trump administration’s plans to cancel the two regional hydrogen hubs on the West Coast, the new list indicated that the Energy Department planned to rescind grants for all seven hubs, Emily reported. “If the program is dismantled, it could undermine the development of the domestic hydrogen industry,” Rachel Starr, the senior U.S. policy manager for hydrogen and transportation at Clean Air Task Force told her. “The U.S. will risk its leadership position on the global stage, both in terms of exporting a variety of transportation fuels that rely on hydrogen as a feedstock and in terms of technological development as other countries continue to fund and make progress on a variety of hydrogen production pathways and end uses.”
Remember the Tesla announcement I teased in yesterday’s newsletter? The predictions proved half right: The electric automaker did, indeed, release a cheaper version of its midsize SUV, the Model Y, with a starting price just $10 shy of $40,000. Rather than a new Roadster or potential vacuum cleaner, as the cryptic videos the company posted on CEO Elon Musk’s social media site hinted, the second announcement was a cheaper version of the Model 3, already the lower-end sedan offering. Starting at $36,990, InsideEVs called it “one of the most affordable cars Tesla has ever sold, and the cheapest in 2025.” But it’s still a far cry from Musk’s erstwhile promise to roll out a Tesla for less than $30,000.
That may be part of why the company is losing market share. As Heatmap’s Matthew Zeitlin reported, Tesla’s slice of the U.S. electric vehicle sales sank to its lowest-ever level in August despite Americans’ record scramble to use the federal tax credits before the September 30 deadline President Donald Trump’s new tax law set. General Motors, which sold more electric vehicles in the third quarter of this year than in all of 2024, offers the cheapest battery-powered passenger vehicle on the market today, the Chevrolet Equinox, which starts at $35,100.

Trump’s pledge to revive the United States’ declining coal industry was always a gamble — even though, as Matthew reported in July, global coal demand is rising. Three separate stories published Tuesday show just how stacked the odds are against a major resurgence:
As you may recall from two consecutive newsletters last month, Secretary of Energy Chris Wright said “permitting reform” was “the biggest remaining thing” in the administration’s agenda. Yet Republican leaders in Congress expressed skepticism about tacking energy policy into the next reconciliation bill. This week, however, Utah Senator Mike Lee, the chairman of the Senate Committee on Energy and Natural Resources, called for a legislative overhaul of the National Environmental Policy Act. On Monday, the pro-development social media account Yimbyland — short for Yes In My Back Yard — posted on X: “Reminder that we built the Golden Gate Bridge in 4.5 years. Today, we wouldn’t even be able to finish the environmental review in 4.5 years.” In response, Lee said: “It’s time for NEPA reform. And permitting reform more broadly.”
Last month, a bipartisan permitting reform bill got a hearing in the House of Representatives. But that was before the government shutdown. And sources familiar with Democrats’ thinking have in recent months suggested to me that the administration’s gutting of so many clean energy policies has left Republicans with little to bargain with ahead of next year’s midterm elections.
Soon-to-be Japanese prime minister Sanae Takaichi.Yuichi Yamazaki - Pool/Getty Images
On Saturday, Japan’s long-ruling Liberal Democratic Party elected its former economic minister, Sanae Takaichi, as its new leader, putting her one step away from becoming the country’s first woman prime minister. Under previous administrations, Japan was already on track to restart the reactors idled after the 2011 Fukushima disaster. But Takaichi, a hardline conservative and nationalist who also vowed to re-militarize the nation, has pushed to speed up deployment of new reactors and technologies such as fusion in hopes of making the country 100% self-sufficient on energy.
“She wants energy security over climate ambition, nuclear over renewables, and national industry over global corporations,” Mika Ohbayashi, director at the pro-clean-energy Renewable Energy Institute, told Bloomberg. Shares of nuclear reactor operators surged by nearly 7% on Monday on the Tokyo Stock Exchange, while renewable energy developers’ stock prices dropped by as much as 15%
Researchers at the United Arab Emirates’ University of Sharjah just outlined a new method to transform spent coffee grounds and a commonly used type of plastic used in packaging into a form of activated carbon that can be used for chemical engineering, food processing, and water and air treatments. By repurposing the waste, it avoids carbon emitting from landfills into the atmosphere and reduces the need for new sources of carbon for industrial processes. “What begins with a Starbucks coffee cup and a discarded plastic water bottle can become a powerful tool in the fight against climate change through the production of activated carbon,” Dr. Haif Aljomard, lead inventor of the newly patented technology, said in a press release.
Last week’s Energy Department grant cancellations included funding for a backup energy system at Valley Children’s Hospital in Madera, California
When the Department of Energy canceled more than 321 grants in an act of apparent retribution against Democrats over the government shutdown, Russ Vought, President Trump’s budget czar, declared that the money represented “Green New Scam funding to fuel the Left's climate agenda.”
At least one of the grants zeroed out last week, however, was supposed to help keep the lights on at a children’s hospital.
The $29 million grant was intended to build a 3.3-megawatt long-duration energy storage system at Valley Children’s Hospital, a large pediatric hospital in Madera, California. The system would “power critical hospital operations during outage events,” such as when the California grid shuts down to avoid starting wildfires, according to project documents.
“The U.S. Department of Energy’s cancellation of funding for [the] long-duration energy storage demonstration grant is disappointing,” Zara Arboleda, a spokesperson for the hospital, told me.
Valley Children’s Hospital is a 358-bed hospital that says it serves more than 1.3 million children across California’s Central Valley. It has 116 neonatal intensive care unit beds and nationally ranked specialties in pediatric neurology, orthopedics, and lung surgery, among others.
Energy Secretary Chris Wright has characterized the more than $7.5 billion in grants canceled last week as part of an ongoing review of financial awards made by the Biden administration. But the timing of the cancellations — and Vought’s gleeful tweets about them — suggests a more vindictive purpose. Republican lawmakers and President Trump himself threatened to unleash Vought as a kind of rogue budget cutter before the federal government shut down last week.
“We don’t control what he’s going to do,” Senator John Thune told Politico last week. “I have a meeting today with Russ Vought, he of PROJECT 2025 Fame, to determine which of the many Democrat Agencies, most of which are a political SCAM, he recommends to be cut,” Trump posted on the same day.
Up until this year, canceling funding that is already under contract with a private party would have been thought to be straightforwardly illegal under federal law. But the Supreme Court’s conservative majority has allowed the Trump administration to act with previously unimaginable freedom while it considers ruling on similar cases.
Faraday Microgrids, the contractor that was due to receive the funding, is already building a microgrid for the hospital. The proposed backup power system — which the grant stipulated should be “non-lithium-ion” — was supposed to be funded by the Energy Department’s Office of Clean Energy Demonstrations, with the goal of finding new ways of storing electricity without using lithium-ion batteries, and was meant to work in concert with that new microgrid and snap on in times of high stress.
That microgrid project is still moving forward, Arboleda, the hospital’s spokesperson, told me. “Valley Children’s Hospital continues to build and soon will operate its microgrid announced in 2023 to ensure our facilities have access to reliable and sustainable energy every minute of every day for our patients and our care providers,” she added. That grid will contain some storage, but not the long-term storage system discussed in the official plan.
Faraday Microgrids, formerly known as Charge Bliss, didn’t respond to a request for comment, but its website touts its ability to secure grants and other government funding for energy projects.
In a statement, a spokesman for the Energy Department said that the grant was canceled because the project wasn’t feasible. “Following an in-depth review of the financial award, it was determined, among other reasons, that the viability of the project was not adequate to warrant further disbursements,” Ben Dietderich, a spokesman for the Energy Department, told me.
The children’s hospital, at least, is in good company. On Tuesday, a Trump administration document obtained by Heatmap News suggested the Energy Department is moving to kill bipartisan-backed funding for two direct air capture hubs in Texas and Louisiana. And although California has lost the most grants of any state, the Energy Department has also sought to terminate funding for new factories and industrial facilities across Republican-governed states.
Editor’s note: This story initially misstated the number of neonatal intensive care unit beds at Valley Children’s Hospital. It has been corrected.
Rob and Jesse break down China’s electricity generation with UC San Diego’s Michael Davidson.
China announced a new climate commitment under the Paris Agreement at last month’s United Nations General Assembly meeting, pledging to cut its emissions by 7% to 10% by 2035. Many observers were disappointed by the promise, which may not go far enough to forestall 2 degrees Celsius of warming. But the pledge’s conservatism reveals the delicate and shifting politics of China’s grid — and how the country’s central government and its provinces fight over keeping the lights on.
On this week’s episode of Shift Key, Rob and Jesse talk to Michael Davidson, an expert on Chinese electricity and climate policy. He is a professor at the University of California, San Diego, where he holds a joint faculty appointment at the School of Global Policy and Strategy and the Jacobs School of Engineering. He is also a senior associate at the Center for Strategic and International Studies, and he was previously the U.S.-China policy coordinator for the Natural Resources Defense Council.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: Your research and other people’s research has revealed that basically, when China started making capacity payments to coal plants, in some cases, it didn’t have the effect on the bottom line of these plants that was hoped for, and also we didn’t really see coal generation go down or change in the year that it happened. It wasn’t like they were paying these plants to stick around and not run. They were basically paying these plants, it seems like, to do the exact same thing they did the year before, but now they also got paid. And maybe that was needed for their economics, we can talk about it.
Why did coal get those payments and not, say, batteries or other sources of spare capacity, like pumped hydro storage, like nuclear? Why did coal, specifically, get payments for capacity? And does it have to do with spinning reserve? Or does it have to do with the political economy of coal in China?
Michael Davidson: When it came out, we said exactly the same thing. We said, okay, this should be a technology neutral payment scheme, and it should be a market, not a payment, right? But China’s building these things up little by little. Over time we’ve seen, historically, actually, a number of systems internationally started with payments before they move to markets because they realize that you could get a lot more competitive pressure with markets.
The capacity payment scheme for coal is extremely simple, right? It says, okay, for each province, we’re going to say what percentage of our benchmark coal investment costs are we going to subsidize. It’s extremely simple. It does not account for how much you’re using it at a plant by plant level. It does not account for other factors, renewables, etc. It’s a very coarse metric. But I wouldn’t say that it had had some, you know, perverse negative effect on the outcome of what coal generation is. Probably more likely is that these payments were seen, for some, as extra support. But then for some that are really hurting, they’re saying, okay, well then we will maybe put up less obstacles to market reforms.
But then on top of that, you have to put in the hourly energy demand growth story and say, okay, well you have all these renewables, but you don’t have enough storage to shift to evening peaks. You are going to rely on coal to meet that given the current rigid dispatch system. And so you’re dispatching them kind of regardless of whether or not you have the payment schemes.
I will say that I was a skeptic, right? Because when people told me that China should put in place a capacity market, I said, China has overcapacity. So if you have an overcapacity situation, you put in place a market, the prices should be zero. So what’s the point? But actually, when you’re looking out ahead with all of this surplus coal capacity that you’re trying to push down, you’re trying to push those capacity factors of those coal plans from 50%, 60%, down to 20% or even lower, they need to have other revenue schemes if you’re not going to dramatically open up your spot markets, which China is very hesitant to do — very risk averse when it comes to the openness of spot markets, in terms of price gaps. So that’s a necessary part of this transition. But it can be done more efficiently, and it should done technology neutral.
And by the way that is happening in certain places. That’s a national scheme, but we actually see that the implementation — for example, Shaanxi province, we have a technology neutral scheme that would include other resources, not just coal.
