Heirloom has an ambitious goal of taking one billion tons of CO2 from the atmosphere by 2035.

Crucially, it intends to do that at a competitive market price. With DAC right now costing $200-$600 per carbon ton, Heirloom’s goal is to reduce that to $100 and then $50.

Right now, Heirloom has no large scale carbon removal facility, on September 2nd, the company put up a blog post asking “Where will Heirloom’s Direct Air Capture facilities be deployed.”

However, the signs are, these won’t be on the drawing board for long.

That’s because in March, Heirloom received one of the largest investments in a DAC company, with $53 million being put in by Carbon Direct Capital Management, Ahren Innovation Capital, and Breakthrough Energy Ventures, with The Microsoft Climate Innovation Fund as an additional participant.

Heirloom’s process works by exposing rocks to the atmosphere and letting them naturally react with CO2 in a process known as “carbon mineralization”.

The rocks are then heated to release the CO2, which is then captured and safely pumped underground into rock formations where it is stored permanently.

While carbon mineralization occurs over long timescales in nature, Heirloom says it can speed up the process substantially, resulting in fewer minerals, less capital expenditure, and less time needed to capture the same amount of CO2
