Climeworks: Orca and Mammoth

Hellisheiði, Iceland

The world’s first commercial Direct Air Capture deployments, paired with subsurface mineral storage.

Climeworks’ Orca is the first operational commercial direct air capture plant in the world, commissioned in 2021. Mammoth, with nearly 4 times the carbon removal capacity, is not far behind, scheduled for completion in 2024. Both plants store CO2 underground in durable mineral form, partnering with CarbFix, a leading Iceland-based innovator in the CO2 mineralization field.

Minus Materials

Boulder, CO, USA

Using algae to generate carbon negative limestone for cement!

With this breakthrough demonstration project Minus Materials will install and operate a first-of-its-kind “regenerative quarry” pilot project in Boulder County that will support the production of carbon-negative biorenewable limestone using microalgae. Limestone produced can be used as a substitute for conventional emissions intensive ‘clinker’, the base component of Portland cement.

Planteers GmbH

Hamburg, Germany

Reactor-based ocean alkalinity enhancement

We exploit CO2 from wastewater treatment facilities, mix it with water and limestone. During the reaction, CO2 is consumed and trapped as alkaline solution. Afterwards, the solution is diluted until it is uncritical for the local aquatic system and discharged into river estuaries or oceans.
Country: Germany

ClimeRock

Colombes, France

Making ERW accessible, starting with France

ClimeRock is a French startup focused on Enhanced Rock Weathering (ERW) – a natural solution that captures carbon dioxide from the air by spreading finely ground rocks over large areas of land. ERW also improves soil health and productivity for farmers. ClimeRock aims to make ERW accessible to farming lands globally, starting with France. ERW utilizes abundant natural resources and has the potential to scale up rapidly to reach net-zero emissions.

Exterra Carbon Solutions

Thetford Mines, Quebec, Canada

Mimics the natural weathering of rocks, significantly accelerating CO2 mineralization

Exterra reduces the environmental impact of carbon emissions and raw material production by developing projects that transform mineral waste and CO2 into carbonate minerals and byproducts using our proprietary chemical process. The carbonate minerals are used on-site for site rehabilitation, where the CO2 remains locked away for millennia, avoiding the climate impact of atmospheric greenhouse gasses.
