From vision to reality: Orca is launched

On September 8, 2021, we launched Orca, the world’s first and largest direct air capture and storage plant, making carbon dioxide removal on large-scale a reality.

We improved the capture capacity of Orca by applying a new technology design. The facility consists of eight collector containers, with an annual capture capacity of 500 tons each. The containers are arranged around a central process hall that accommodates all electrics, such as the processing unit, allowing us to operate and control the facility from afar.  

The heat and electricity required to run the direct air capture process is supplied by the Hellisheidi Geothermal Power Plant. An important aspect was that Orca is smoothly integrated into the beautiful Icelandic landscape. We therefore chose earthy colours and natural materials that give it a natural touch.
