Germany: CI4C has installed the final modular component of its carbon purification unit (CPU) at the Schwenk Zement plant in Mergelstetten. The unit is 31m long with a cross-section of 5 x 5m, installed using a tandem lift.

The unit completes major construction work at the CO₂ capture pilot project. The CPU will clean and liquefy CO₂-rich exhaust gas from the oxyfuel kiln and processes it to food-grade quality, enabling its reuse in purified form. Final mechanical and electrical works are underway ahead of commissioning in late summer 2025.

European cement producers Buzzi, Dyckerhoff, Heidelberg Materials, Schwenk Zement and Vicat established CI4C in 2019 to implement the catch4climate initiative. The 450t/day clinker line and CPU have been purpose-built at the plant, which has received investment of over €120m, and will be used solely for research and development.

Germany: The Catch4Climate project says it is ready to build an oxyfuel pilot unit at Schwenk Zement’s Mergelstetten plant following approval by the Stuttgart Regional Council. The project comprises Dyckerhoff, Heidelberg Materials, Schwenk Zement and Vicat, and It has set up a research company called CI4C to run it. Over Euro120m will be invested towards building a dedicated 450t/day production line to test the oxyfuel process. Jürgen Thormann, the Technical Managing Director of CI4C, said that this is the first time a so-called ‘pure’ oxyfuel process will be used for CO₂ capture. At a later stage in the project the consortium plans to use the captured CO₂ to produce so-called ‘reFuels’, climate-neutral synthetic fuels such as kerosene for aircraft, with the help of renewable electrical energy. Commissioning of the unit is scheduled for mid-2024.

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.
