Heirloom Technologies

Heirloom builds low-cost Direct Air Capture technology that permanently removes CO2 at a billion-ton scale.

Why we invested

Carbon removal will be necessary for us to reach our goal of mitigating the worst effects of climate change. The viable solutions will need to be low-cost, low-energy, and scalable. Heirloom’s technology, which dramatically enhances natural carbon sequestration systems, will be part of the future of carbon dioxide removal.

Why this work matters

By mid-century, we’ll need to remove billions of tons each year if we want to keep temperature rise below 1.5°C. We need to permanently remove CO2 from the atmosphere, and Heirloom's low-cost Direct Air Capture technology is one of the best solutions available to do this today.
