The groundbreaking of Climeworks’ newest and largest direct air capture and storage plant represents a demonstrable step in the company’s ambitious scale-up plan: multi-megaton capacity by 2030, on track to deliver gigaton capacity by 2050. In September 2021, Climeworks began operations of Orca, its first-of-a-kind plant, kick-starting the supply availability of high-quality carbon removal. Following a recent equity raise of USD 650m, Climeworks is focused on rapidly scaling-up capacity on the market.
It will concentrate on implementing large modular direct air capture and storage facilities, investing in technological development, and growing its organization globally.
Mammoth is Climeworks’ 18th project and its second commercial direct air capture and storage plant. It is designed with a nominal CO₂ capture capacity of 36’000 tons per year when fully operational – an order of magnitude larger than its Orca. Located in Iceland, construction is expected to last 18-24 months before operations start.
Carbfix, Climeworks’ CO₂ storage partner, will provide the permanent underground storage of carbon dioxide. The Hellisheiði electricity power plant operated by ON Power will supply Climeworks’ Mammoth plant and the Carbfix CO₂ injection sites with renewable energy to run the entire direct air capture and storage process.
Mammoth is designed to further expand supply and provide engineering experience for Climeworks’ 10x scale-up steps. It capitalizes on a very dynamic market demand – with several 10-year offtake agreements signed over the last months – and technology learnings from operating Orca.
