Description
A facility that can capture up to 1,000 tons of CO2 per year.
The CO2 will be stored in concrete to fulfill commercial removal purchases. The sequestration is executed through a partnership with CarbonCure Technologies. Buyers of Heirloom’s CO2 removal credits include Microsoft, Stripe, Shopify, and Klarna.
Heirloom claims the facility, which was inaugurated on 9 November 2023, is the United States’ first commercial Direct Air Capture facility.
The facility is powered by renewable energy supplied by Ava Community Energy.
Heirloom’s technology uses limestone to pull CO2 from the air. The limestone is heated through a renewable-energy-powered kiln to absorb CO2, leaving a mineral powder. The powder is spread on vertically stacked trays where it acts like a sponge, pulling CO2 from the air.
It is located in Tracy, California.
