Changing up the recipe to make low-carbon cement

Changing up the recipe to make low-carbon cement

Ingrid Lobet of Canary Media writes on how one startup is creating low-carbon cement.

The C3 Take
  • Brimstone Energy is a startup that is looking to decarbonize cement by using calcium silicate rocks instead of limestone.
  • Calcium silicate contains no carbon and requires a lower temperature than limestone to extract the calcium and oxygen that are needed to create cement.
  • Introducing new materials into the cement market is difficult, with one report citing “[p]rescriptive standards, outdated or restrictive procurement criteria, and cozy industry relationships” as the reason why.
  • Brimstone Energy is showing that private sector is finding the innovations that are needed to reduce emissions.

“Brimstone Energy is an early-stage startup that’s currently raising money to build a pilot production facility. It raised an initial $2 million starting in 2019 from the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), the National Science Foundation and a number of other sources.”
