Since it became evident that projected emission cuts alone would not slow global warming in line with targets, the scientific endeavour to capture and store carbon dioxide (CO2) has accelerated. Technologies have developed to capture CO2 emitted from power stations and industrial processes; the gas is then compressed and transported for storage. Storage typically involves injecting pure CO2 into underground rock that is particularly reactive. Over thousands of years the CO2 will naturally react with the rock to form a solid mineral, a process called mineralisation.

Carbfix’s technology accelerates the mineralisation by dissolving CO2 in water prior to or during injection, which essentially fast forwards the first few steps of the natural underground process. Carbfix then injects the carbonated (sparkling!) water underground, where the mineralisation process rapidly completes. The shortened time frame (years versus millenia) eradicates the risk of CO2 leakage, which gives CO2 producers confidence that their emissions have been securely and permanently stored.

Carbfix’s development pace is impressive: three years from concept to pilot, then four years from pilot to industrial scale. However, global annual CO2 emissions are upwards of 35 billion tonnes, whereas the annual capacity of Carbfix’s storage site at the Hellisheidi geothermal power plant, for example, is 20,000 tonnes. Large cost reduction in the carbon capture and storage chain is needed to achieve the scale up necessary for Carbfix, and other carbon storage technologies, to play a meaningful role in reaching net zero. A developed, internationally-coordinated market for CO2 avoidance, including incentives, will be essential in making carbon capture and storage technologies viable.

  • Prepare for full-scale implementation of the carbon capture and storage system at Hellisheidi power plant supported by a EUR 3.9 million EU grant.
  • Drill first injection well for their flagship storage facility, the Coda Terminal, which will store CO2 shipped in from different capture sites in Northern Europe.
  • Three other pilot injections at new sites across Europe.

Public and private owners of power plants who are aiming to reduce their net emissions (power plants are ideally suited to maximise carbon capture and storage technologies). Public sector organisations, companies, or individuals looking for exciting carbon offsetting options.
