Rising demand for housing in most major cities around the world is increasingly at odds with efforts to reduce greenhouse emissions, as the literal building blocks—concrete and cement—of the construction projects are extremely polluting. Roughly 7% of all carbon emissions today come from cement production, making it one of the highest-emitting industrial sectors, according to …

Synhelion and Cemex announced today a significant milestone in their joint effort to develop fully solar-driven cement production: the scaling of their technology to industrially-viable levels. This includes the continuous production of clinker, the most energy-intensive part of cement manufacturing, using only solar heat. At the beginning of 2022, the companies announced the first-ever successful …
CEMEX, S.A.B. de C.V. («CEMEX») announced today that the U.S. Department of Energy awarded US$3.2 million to Solar MEAD, a joint project headed by CEMEX, Sandia National Laboratories, and Synhelion, which aims to decarbonize cement production. Solar MEAD aims to replace the use of fossil fuels with concentrated solar thermal (“CST”) energy in clinker production, …
Microsoft co-founder Bill Gates entered the world of cement this week with a public relations blitz for Heliogen. He’s one of the backers of a new Californian technology startup looking to use concentrated solar power (CSP) to power heavy industrial processes like clinker or steel production. The company says it has concentrated solar energy commercially …

Use of solar energy in the calcination process to minimise carbon dioxide emissions during cement production. Rotary kiln successfully tested in the solar simulator at the DLR Institute of Solar Research in Cologne. Can be used in Southern Europe and emerging markets. Solar researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und …
