Unprecedented extreme weather events have dominated the news headlines since early this year. The United Nation’s Intergovernmental Panel on Climate Change cautions that the world will see more of this in years to come. The report further confirms that it is crucial to reduce our emissions drastically and remove unavoidable and historic carbon dioxide emissions from the air permanently.

One month after the report was published, Climeworks launches Orca, the world’s largest direct air capture and storage plant that permanently removes CO₂ from the air.

Orca at a glance

The construction of Orca started in May 2020. It is based on advanced modular technology in the form of innovative stackable container-size collector units. These units are powerful and compact with minimal physical footprint. This has made it possible for Orca to be operational in under 15 months. Compared to the previous technology generation, the use of steel in the collector units has roughly been reduced by half per output unit. Orca also supports the expansion of Climeworks. The technology can easily be replicated at different locations worldwide and on ever larger scales. In a flexible manner wherever ample renewable energy and storage conditions are available. Strategically located adjacent to ON Power’s Hellisheiði Geothermal Power Plant, Orca runs fully on renewable energy.

Orca is the first-of-its-kind plant that translates the vision of industrial-scale direct air capture and storage into reality. This improved technology generation comes in an award-winning new design, which embodies the interconnection between nature and technology. Climeworks has been able to intensify the process leading to increased CO₂ capture capacity per module. This optimized process means that more carbon dioxide can be captured and stored than ever before.

Expansion is around the corner

This innovation in plant design is a key enabler to rapidly scale up this much-needed climate technology in the years to come. Since Orca is now a reality and in operation, Climeworks is on track to ramp up its capture capacity significantly. This will be required in light of the strong market demand as shown through long-term partnerships with, among others, Microsoft, Swiss Re, Shopify and commitments from over 8’000 private individuals. Climeworks inspires and supports more pioneering companies and individuals to act now and remove carbon dioxide from the air.

Partnership with Carbfix and ON Power

Strong partnerships with pioneering Icelandic companies support the excellent conditions for the scale up. ON Power, the Icelandic geothermal energy provider, supplies clean renewable energy to power the Orca plant. Carbfix, experts in rapid underground mineralization, mix the air-captured CO₂ with water. They then pump it deep underground, where it is trapped in stone through a natural mineralization process that takes under two years.
