Climeworks takes another major step on its road to building gigaton DAC capacity

News | 28.06.2022

Key take-aways:

  • Climeworks breaks ground in Iceland to build its newest and largest direct air capture and storage facility, called Mammoth
  • With a nominal CO₂ capture capacity of 36’000 tons per year when fully operational, Mammoth represents a demonstrable step in Climeworks' ambitious scale-up plan: multi-megaton capacity by 2030, on track to deliver gigaton capacity by 2050
  • Mammoth capitalizes on a very dynamic market demand – with several 10-year offtake agreements signed over the last months – and technology learnings from operating Orca

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.

“Today is a very important day for Climeworks and for the industry as construction begins on our newest, large-scale direct air capture and storage plant. With Mammoth, we can leverage our ability to quickly multiply our modular technology and significantly scale our operations. We are building the foundation for a climate-relevant gigaton-scale capacity, and we are starting deployment now to remain on track for this.”

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.

“Based on most successful scale-up curves, reaching gigaton by 2050 means delivering at multi-megaton scale by 2030. Nobody has ever built what we are building in DAC, and we are both humble and realistic that the most certain way to be successful is to run the technology in the real world as fast as possible. Our fast deployment cycles will enable us to have the most robust operations at multi-megaton scale.”
