Renewable energy researchers have been looking into how to cut CO2 emissions from processing industrial minerals like cement and lime, as these are responsible for a high share of the global greenhouse gas emissions.

For every 10 tons of cement we produce, we release 9 tons of CO2, with much of that through the burning of fossil fuels to heat the reaction. So, instead of burning a fossil fuel, researchers are investigating substituting a solar technology; a solar reactor that creates the heat needed to process the particles.

Supported by Europe’s SOLPART H2020 project they have already tested a solar reactor at lab scale, one at DLR in Germany, and the second at France’s National Centre for Scientific Research CNRS-PROMES (PROcédés, Materials and Solar Energy).
