Germany: The Catch4Climate project has moved into the planning stage of its oxyfuel pilot plant at the Mergelstetten cement plant. The group, comprising Buzzi Unicem’s subsidiary Dyckerhoff, HeidelbergCement, Schwenk Zement and Vicat, signed a letter of intent with the state’s prime minister and transport minister in Stuttgart in mid-November 2020.
The consortium intends to build and operate its own demonstration plant on a semi-industrial scale, to use the oxyfuel process to capture CO2. In the future, the captured CO2 will be used to produce so-called ‘reFuels’, climate-neutral synthetic fuels such as kerosene for air traffic, with the help of renewable electrical energy.
The cement producers formed CI4C – Cement Innovation for Climate in late 2019. The aim of the Catch4Climate project is to create the basis for a large-scale application of CO2 capture technologies in cement plants enabling the later use of CO2 as a raw material in other processes such as a carbon capture and utilisation/storage.
