Direct air capture business Heirloom Carbon Technologies, based in San Francisco, California, has raised $150m in its latest fundraising round – almost three times the amount it brought in from its prior funding round two years ago.
The scale-up business opened the first direct air capture facility in the US last year. It now has two more under construction in Louisiana.
Heirloom was founded in 2020 and is also involved in one of the US Department of Energy-backed regional direct air capture hubs. Each of these is targeting 100 million tonnes of carbon dioxide captured each year once operational.
For now, Heirloom is working on the facility in Louisiana that it hopes will be able to capture about 17,000 tonnes of CO2 a year and be up and running in 2026.
