About

Sustaera is a North Carolina-based Direct Air Capture startup spun out of Susteon Inc. and founded in 2021, developing a modular DAC system using natural-mineral sorbents and integrated electric resistive heating. Backed by Breakthrough Energy Ventures, the Grantham Foundation, the U.S. DOE, and XPRIZE, the company announced a major efficiency breakthrough in March 2026, claiming 90%+ energy efficiency and a path to sub-$100/ton DAC. The company is pursuing a licensing model for project developers.
