News DOE provides funding to Solar MEAD project

DOE provides funding to Solar MEAD project

Written by Global Cement staff 17 February 2023

US: The US Department of Energy (DOE) has awarded US$3.2m to Solar MEAD, a project that aims to replace fossil fuels with concentrated solar thermal (CST) energy in clinker production. Solar MEAD is jointly led by Cemex, Swiss solar fuels innovator Synhelion and Sandia National Laboratories, a research and development laboratory run by the DOE.

Synhelion’s CST technology generates hot gas at 1500°C, high enough to produce clinker without any thermal fuels. Cemex and Synhelion produced a batch of clinker with CST in a research setting in Spain in 2022. In the Solar MEAD project, Sandia National Laboratories will contribute its research facilities in New Mexico and subject expertise to help accelerate the adaptation of the technology for use in cement manufacturing. The projects aims are to increase the efficiency of CST technology by improving heat transfer from the hot gas to the cement raw mix and further reduce the CO2 emissions of the process.
