The scale of the carbon capture and storage operation taking CO2 directly from the air at Hellisheiði, southwest Iceland, is set to grow tenfold with the new Climeworks facility being set up in collaboration with Carbfix and Orka náttúrunnar (ON Power).

‘Mammoth’ is Climeworks’ 18th project and will be the company’s second from-air sequestration plant operating directly with carbon storage on the same site. Its first, ‘Orca’, went into operation last autumn.

“This project is an important step in developing and scaling the technology to capture CO2 directly from the atmosphere and it is benefitting from Carbfix’s ten years of experience in calcifying CO2 in a secure manner,” writes Carbfix CEO Edda Sif Pind Aradóttir in a statement.

Carbfix is also involved in a new project with Landsvirkjun, it was announced this week. That project will capture carbon from Þeistareykjastöð power station and calcify it in rocks. The company will also help Landsvirkjun reduce emissions from the Krafla geothermal plant by changing aspects of how the plant works. The project has been named ‘Koldís’ and is slated to be fully operational during 2025.

“Koldís is an important project that we at Landsvirkjun are taking on for the coming years. It is yet another example of our great motivation in climate matters, where we have set ourselves the clear goal of carbon neutrality in 2025,” Hörður Arnason, Landsvirkjun director, writes.

The statement notes that since 2008, Landsvirkjun has reduced its carbon footprint by 61 percent and is aiming for carbon neutrality by 2025.

The statement from Carbfix says that global carbon emissions need to drop fast and that capture and storage from the atmosphere is necessary in most of the scenarios that envisage capping global temperature rise at 1.5°C or less.

“For the climate targets to be reached, emissions of CO2 need to be cut fast, but in addition, large steps are needed in capturing and storing that which has been emitted. Our process, which is based on changing CO2 into minerals, which is the safest and longest-lasting means of storage,” Edda Sif adds.
