Ensuring captured CO2 is stored in a durable way is challenging. DAC technologies and hard-to-abate industries have different end uses for captured CO2, which highly vary on durability of removal. The higher the durability of CO2 removal, the greater the impact on mitigating climate change, and the higher the quality of carbon credits.
44.01 converts CO2 into inert rocks in geological reservoirs through carbon mineralization. Their technology accelerates this naturally occurring process by injecting CO2 dissolved in water into engineered boreholes in hydraulically isolated and permeable peridotite aquifers and optimizing subsurface pressures and temperatures. The fluid reacts with the peridotite, resulting in the precipitation of carbonate minerals, permanently immobilising the CO2 in solid form.
