Spain: Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO2, using solar heat. La Tribune de Genève Online News has reported that Synhelion’s thermochemical reactor further helps to capture CO2 emissions from clinker production. A study by the Swiss Federal Institute of Technology Lausanne indicated that this can halve the cost of carbon capture at cement plants, to below Euro85/t.
