Clinker is produced by fusing limestone, clay and other materials in a rotary kiln at temperatures around 1500°C. Fossil fuels are typically used to heat the kiln and are responsible for around 40% of the direct CO 2 emissions from the process. Replacing fossil fuels entirely with solar power is a game-changer in industry’s efforts to achieve carbon neutrality by 2050.

“The production of the first solar clinker is an exciting step for this processing technology. This is proof of our commitment to deliver tangible results through innovation to achieve our goal of providing only CO2-free concrete by 2050,” said Fernando A. Gonzalez, CEO of CEMEX. “CEMEX is building a better future, and that future must be sustainable.”

Synhelion and CEMEX R&D teams have set up a batch production pilot unit to produce clinker from concentrated solar radiation by connecting the clinker production process with the Synhelion solar receiver. The pilot was installed in IMDEA Energy’s ultra-high concentration solar tower, located in Spain. Synhelion’s solar receiver delivers record temperatures exceeding 1,500°C. The solar receiver heats a gaseous heat transfer medium and thus supplies the process heat required for the production of clinker.

“Our technology converts concentrated sunlight into the hottest existing solar process heat – over 1500°C – on the market,” said Dr. Gianluca Ambrosetti, CEO and co-founder of Synhelion. “We are proud to demonstrate with CEMEX a specific industrially relevant application of our fully renewable high temperature solar heat.”

The pilot is the first successful calcination and, more importantly, the first successful clinkerization ever performed using only solar energy. The clinker was used to produce cement and was then processed to produce concrete. In the next phase of their joint research and development project, CEMEX and Synhelion aim to produce solar clinker in larger quantities as they work on an industrial-scale pilot project at a cement plant.

This initiative is part of CEMEX’s Future in Action program, which focuses on reducing the carbon footprint of its operations and products to deliver net-zero CO2 concrete globally by 2050. Central to this strategy is CEMEX Ventures and its R&D center in Switzerland. Through them, CEMEX discovers and invests in the companies they believe will provide the proven and scalable technologies to achieve carbon neutrality.

About Synhelion

Synhelion is a global pioneer in the field of sustainable solar fuels. The clean energy company spun off from the Swiss Federal Institute of Technology Zurich (ETH Zurich) in 2016 to decarbonize transport. Solar fuels can replace all types of fossil fuels as they are economically viable and fully compatible with existing global infrastructure. Synhelion’s unique technology converts concentrated solar heat into the hottest process heat on the market, enabling an unprecedented number of industrial processes such as fuel production and cement manufacturing to be driven with solar heat. The company already works with international partners such as the Lufthansa Group, Wood, Eni, CEMEX and Zurich Airport. For more information, please visit: www.synhelion.com.
