World‘s largest direct air capture plant in Iceland

The world’s largest direct air capture plant, Mammoth, has started operations in ON Power‘s Geothermal Park in Hellisheidi. The plant is owned by the Swiss company Climeworks, a global leader in direct air capture technology. Mammoth will be able to capture up to 36 thousand tons of carbon dioxide (CO2) per year directly from the atmosphere when it reaches full capacity.

Climeworks collaborates with Carbfix which receives the CO2 captured by the plant and permanently sequester it by injecting it into deep basaltic rock formations, where the CO2 rapidly turns into stable carbon minerals through natural processes.

Climeworks’ goal is to remove the amount of carbon dioxide that scientists estimate is necessary to meet the world’s climate goals, in addition to dramatic reduction of emissions.

ON Power and Climeworks have had a strong collaboration since Climeworks began operations in Iceland in 2017 in the Geothermal Park. From a test-facility, to the Orca plant capturing 4.000 tons of CO2 annually and to the start-up of Mammoth this year, we are proud of this significant addition to the Geothermal Park and to be a part of an important step in combating global warming. The purpose of Geothermal Park is to support forward-looking and sustainability-minded companies and fully utilize the resource streams of Hellisheiði power plant in a responsible and environmentally friendly way.

ON Power has significantly reduced CO2 emissions from Hellisheidi power plant through capture and disposal in cooperation with Carbfix. The goal is to have the plant carbon neutral by 2025 and ON Power fully carbon neutral by 2030.
