Cement Producers have founded an Oxyfuel Research Corporation
On 6 December 2019, the four European cement producers Buzzi Unicem - Dyckerhoff, HeidelbergCement AG, SCHWENK Zement KG and Vicat founded the joint research corporation CI4C – Cement Innovation for Climate – which is currently waiting for final approval from the antitrust authorities. Aim of the corporation is to realise the joint research project catch4climate, which will investigate the practical applicability of the Oxyfuel Carbon Capture technology in the cement production process.
The oxyfuel technology (from oxygen and fuel) is a clinker burning technology where pure oxygen is introduced into the kiln system instead of ambient air to assure proper combustion of all primary and secondary fuels for heat generation. In this way, exhaust gas with very high purity of CO₂ is produced in the kiln, which considerably improves the CO₂ capture potential. The goal is to capture 100% of the CO₂ emissions of a cement plant in a cost-efficient way. The catch4climate project will investigate options for the widespread use of this carbon capture technology in cement plants in order to enable a subsequent use of the captured CO₂ for instance as raw material in other industrial processes (CCU, CCS). With this project, the European cement industry could contribute to the significant reduction of process-related CO₂ emissions, thereby providing an important contribution to climate protection.
In the frame of the catch4climate project, the four partner companies of the CI4C research corporation will build and operate an oxyfuel test facility on a semi-industrial scale at the premises of the Mergelstetten cement plant in Southern Germany. Upon receipt of all necessary operational and emission-related permits, the official launch of the project is planned for 2020.
About HeidelbergCement
HeidelbergCement is one of the world’s largest integrated manufacturers of building materials, with leading market positions in aggregates, cement and ready-mixed concrete. The company employs some 57,000 people at more than 3,000 locations in around 60 countries.
HeidelbergCement has committed itself to reduce its specific net CO₂ emissions per tonne of cement by 30% compared to 1990 by 2030. This target has been approved by the Science Based Target initiative (SBTi) and is in line with the goals of the Paris Agreement, making HeidelbergCement the first cement company worldwide to have approved science-based CO₂ reduction targets. HeidelbergCement will realise its vision of carbon neutral concrete – at the latest – by 2050.
