4. Powering up mammoth-sized CDR project

This week, Climeworks turned on its second and newest commercial direct air capture (DAC) and storage plant "Mammoth" in Iceland — the world’s largest DAC plant to date.
Mammoth:
- Uses low-temperature geothermal energy technology;
- Targets removing up to 36,000 metric tons of carbon annually; and
- Captured its first CO₂, with 12 of its total 72 collector containers installed onsite.
What’s next: Climeworks is developing multiple projects in the U.S., notably Project Cypress in Louisiana, which will capture up to 1 million metric tons annually, with operational and testing experience derived from its now two commercial plants in Iceland.
What’s clear: Mammoth is Climeworks’ second commercial project, after the Orca plant, also in Iceland, which has a capacity of 4,000 tons a year and was previously the world’s largest operational site.
