Climeworks doubles carbon capture output at its Iceland plant
Climeworks says design upgrades have doubled the carbon-capture output of its Mammoth plant in Iceland while halving the cost per ton removed.
Swiss carbon removal company Climeworks says upgrades to its Mammoth direct air capture facility in Iceland have more than doubled how much CO2 the plant can pull from the atmosphere, while cutting the cost per ton removed in half. The improvements, rolled out over 18 months, centered on a redesigned sorbent — the material that filters CO2 out of ambient air — along with mechanical changes to the plant's collector units.
Mammoth is Climeworks' second direct air capture plant, following the smaller Orca facility that opened in 2021; Mammoth itself began operating in 2024. The company, founded in 2009, says it is the only firm that has been selling direct air capture-based carbon removal to customers for several years running.
Climeworks plans to test a next-generation version of the technology at Mammoth in early 2027. Lab results so far show the sorbent lasting ten times longer and the process running four times more densely, which the company says could let it capture the same amount of CO2 with far fewer collector containers.
