CU Boulder produces carbon neutral cement with microalgae

June 27, 2022 |

In Colorado, a CU Boulder-led research team has figured out a way to make cement production carbon neutral—and even carbon negative—by pulling carbon dioxide out of the air with the help of microalgae

The CU Boulder engineers and their colleagues at the Algal Resources Collection at the University of North Carolina Wilmington (UNCW) and the National Renewable Energy Laboratory (NREL) have been rewarded for their innovative work with a $3.2 million grant from the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency–Energy (ARPA-E). The research team was recently selected by the HESTIA program (Harnessing Emissions into Structures Taking Inputs from the Atmosphere) to develop and scale up the manufacture of biogenic limestone-based portland cement and help build a zero-carbon future.
