Biden bets billions on tech that sucks carbon out of the air

The Biden administration is throwing its weight behind technology that sucks planet-warming carbon dioxide out of the air, selecting the first winners of a $3.5 billion fund dedicated to developing the machines scientists say will be needed to stop the worst effects of climate change.

Projects proposed by a subsidiary of Occidental Petroleum Corp. for Kleberg County, Texas, and by Climeworks AG, Battelle Memorial Institute and Heirloom Carbon Technologies, Inc. for Calcasieu Parish, Louisiana, were selected for the first tranche of funding, up to $1.2 billion, the Energy Department said.

The technology is "essentially a giant vacuum that can suck decades of old carbon pollution straight out of the sky," Energy Secretary Jennifer Granholm told reporters. "If we deploy this at scale, this technology can help us make serious headway toward our net-zero emission goals."

Once operational, the hubs are expected to remove more than 2 million metric tons of carbon dioxide a year from the atmosphere, the equivalent of taking nearly half a million gas-powered cars off the road, Granholm said. Additional projects are expected to be announced next year, the Energy Department said.

In addition, the agency said it had selected 19 projects for smaller "award negotiations," including a $3 million award for a direct air capture (DAC) hub proposed by a division of Chevron U.S. Inc. in San Roman, California, and a $12.5 million award for the Wyoming Regional Direct Air Capture Hub proposed by privately held Carbon Capture Inc.

DAC involves using machines to pull CO₂ out of the ambient air and store it using a variety of techniques. The industry is young and still maturing. Swiss startup Climeworks operates the largest DAC plant in the world in Iceland, which is able to capture 4,000 tons of CO₂ annually. That's equivalent to a few seconds of humanity's carbon emissions.

The company is currently building a plant that it says will be capable of capturing 36,000 tons of CO₂ each year, and other startups are looking to build plants capable of grabbing thousands of tons of the greenhouse gas from the air. Even with these efforts, DAC remains costly and requires a large amount of energy.

Carbon capture: The vacuum the climate may depend on

The world will need DAC as well as other forms of carbon dioxide removal to scale up rapidly in the coming decades. Nearly every scenario to limit global warming to 1.5C, a target set under the Paris Agreement, will require removing billions of tons of carbon from the atmosphere each year by mid-century, climate scientists say.

A good milepost to gauge whether that's achievable will be if the industry can capture 1 million tons of CO₂ a year by 2030. The market for those services could reach $1 trillion before the end of the 2030s, according to BloombergNEF research, if the world prioritizes high-quality carbon removal over offsets.

About 18 direct air capture projects are operating around the world, but the ones being announced by the Energy Department will become the first commercial-scale deployment in the U.S., said Sasha Stashwick, director of policy for Carbon180, an organization focused on carbon removal policy. The overall funding represents a 400-factor increase in DAC capacity, she said.

"This is a really big deal in the world of carbon removal," Stashwick said. "This is going to be the largest deployment of carbon removal ever."
