Climeworks and 44.01: exploring new storage locations for CO₂

To keep global warming to safe levels, science agrees that is not enough to only reduce emissions – we have to remove CO₂ from the atmosphere that has already been emitted. Climeworks’ direct air capture technology can capture unavoidable as well as historic CO₂ emissions directly from the air. Combined with a safe and permanent storage solution, the CO₂ is removed from the air for good. The modular technology can be stacked to build machines of any size and is solely powered by renewable energy. After building and operating several plants all over Europe, Climeworks’ technology will now be tested under the climatic and geological conditions in the Middle East. This is an important step to unlock the global potential for direct air capture and storage solutions urgently needed to fight climate change.

We are excited to explore the potential to store CO₂ from Climeworks’ direct air capture in Oman together with 44.01. The geological conditions as well as the high availability of renewable energy make this a perfect location for testing prior to expanding our technology portfolio.

Geological storage of CO in peridotite

Oman has the perfect conditions to store CO₂ through the natural process of mineralization in peridotite. Carbon mineralization occurs naturally in alkaline environments: atmospheric CO₂ reacts with peridotite rocks which are rich in magnesium and calcium, to precipitate carbonates. Oman bears the potential to store trillions of tons of CO₂ permanently and safely in peridotite formations. Thereby, the CO₂ is permanently removed in natural geological carbon sinks and cannot escape back into the atmosphere. Additionally, renewable energy is abundant in Oman and 44.01 powers its process with solar energy and biofuel produced by local circular economies.

More about geological storage of CO

To enable direct air capture and storage technologies to fulfill their foreseen role in climate change mitigation, storage solutions have to be scalable to billions of tons of CO₂ per year. Geological storage of CO₂ combines the scalability and technical maturity on the one hand with safety and permanence on the other. Scientific estimates show that the global potential for geological storage of CO₂ outweighs all greenhouse gases ever emitted since the Industrial Revolution. Geological mineralization in suitable rock formations is seen as the safest, most scalable and permanent approach of CO₂ storage as it is a natural process that is able to store CO₂. One location in which these suitable rock formations occur is Oman. This is why Climeworks and 44.01 are jointly testing the combination of Climeworks’ direct air capture technology with geological storage of CO₂ in Oman.

We are delighted to be collaborating with Climeworks on such an important project. Climeworks is a pioneer in the field of direct air capture and brings in a lot of expertise. The launch of this direct air capture plant is a major step forward for the region which has some of the highest CO₂ emissions per capita in the world.
