The IPCC revealed in their 2018 Special Report, with high confidence, that every pathway to limit warming to 1,5° requires avoiding CO2 emissions in the future as well as removing existing CO2 in the atmosphere today.

Heirloom Carbon Technologies has the ambitious goal of removing 1 billion tons of CO2 by 2035 through direct air capture technology that extracts CO2 from the ambient air using common minerals.

The process works by exposing rocks to the ambient air and letting them naturally react with CO2 in a process known as “carbon mineralization”. The rocks are heated to release the CO2, which is then captured and safely pumped underground into rock formations where it is stored permanently.

Carbon mineralization occurs over long timescales in nature, but Heirloom’s technology speeds up the process substantially. The resulting process uses fewer minerals, less capital and captures more CO2 in the same timeframe as it would naturally. Their goal is to be able to do this at a cost less than $100 USD per ton.

Heirloom has recently raised millions in funding from investors including Breakthrough Energy Venture, a clean-technology fund led by Bill Gates, and the Microsoft Climate Innovation Fund. Corporations such as Stripe Inc., Klarna Bank AS and Wise Plc have already invested, anticipating that the technology will scale and costs will go down.

Heirloom Carbon Technologies is building a solution that doesn't compromise the health of people or the environment. For more information on Heirloom, check their website or read their white paper.
