Building largest direct air capture and storage plant starts in Iceland


Iceland – Mammoth, Climeworks’ newest and largest direct air capture and storage plant, has officially broken ground in Iceland.

Climeworks’ ground-breaking Orca plant went into operation in September 2021, launching the supply of high-quality carbon removal. Mammoth is the second commercial direct air capture and storage facility built by Climeworks and its 18th project overall. When fully operational, it is expected to have a nominal CO2 capture capacity of 36,000 tons per year, which is significantly more than its Orca. Construction is anticipated to last 18 to 24 months before operations begin at the Icelandic facility.

The long-term underground storage of carbon dioxide will be provided by Climeworks’ CO2 storage partner, Carbfix. The entire direct air capture and storage procedure will be powered by renewable energy from the ON Power-operated Hellisheii electricity power plant, which will also supply the Carbfix CO2 injection sites and Climeworks’ Mammoth plant.

Scale up

Mammoth is made to increase supply even more and give engineers experience in preparation for Climeworks’ 10x scale-up steps. With several 10-year offtake agreements signed in recent months, the market demand is very dynamic, and it takes advantage of technological advancements from running Orca.
