Company Description

Sublime is developing a breakthrough process to make low-carbon cement. The technology replaces the industry's legacy fossil-fuel-intensive thermal calciner process with an electrochemical process that produces low-carbon cement at ambient temperatures with renewable electricity. Sublime was started in 2020, as a spin-out of Yet-Ming Chiang's lab at MIT (Form Energy, A123, American Superconductor, 24M, Desktop Metals).
