Heirloom’s mission

Heirloom aims to remove one billion tons of carbon dioxide by 2035 through natural processes. Its system of capturing, processing, and storing CO2 is the world’s most cost-effective direct air capture solution. Once it captures the CO2, Heirloom compresses and pumps it underground into geological reservoirs for safe and permanent storage.

Design & Make

Safely removing atmospheric CO2 emissions

Heirloom’s DAC technology accelerates limestone’s natural ability to sequester CO2, enabling its safe and permanent storage in materials like concrete.

“Our technology rapidly accelerates the natural processes that enable limestone to absorb CO2 from the air from a timespan of years to days.”

Fighting climate change with AutoCAD

Using AutoCAD and other Autodesk software, Heirloom is designing DAC via carbon mineralization devices that can withstand natural forces while achieving durability and cost goals for scale.
