Heirloom’ s direct air capture facilities

HEADQUARTERS: SAN FRANCISCO BAY AREA, CALIFORNIA, US CEO: SHASHANK SAMALA

Heirloom is built around carbon mineralisation, using naturally occurring chemistry to pull CO₂ from the air and lock it away. The company has gained attention for its cost ambition and for presenting direct air capture in a more nature-based, scalable form. Its strategy is to make removal durable, commercially viable and compatible with large-scale deployment. Heirloom’ s rise reflects investor appetite for technologies that promise both permanence and lower costs than many early DAC approaches.
