Denmark: FLSmidth says it will lead CO₂Valorize, a new consortium intended to develop and deploy carbonation technologies in the cement industry. The group will receive Euro2m from the Marie Skłodowska-Curie Doctoral Networks and is supported by the European Commission’s Horizon Europe initiative. The expected commercial and technical outcomes of the consortium include a full flow sheet of the carbonation process line, the techno-economic analysis of various technology and materials options, and the optimisation of FLSmidth's proprietary reactors. The project is also intended to be a key part of FLSmidth MissionZero programme.

Burcin Temel McKenna, Head of Green Cement Solutions Development at FLSmidth, said “We have been granted a unique opportunity to revolutionise the cement industry at a time of extreme urgency”. He added, “On-site carbon capture and utilisation projects will be a quicker and more economically viable way forward for in cement plants.”

The consortium includes the following partners: Norwegian University of Science and Technology; Karlsruhe Institute of Technology; HZDR Innovation with Helmholtz-Zentrum Dresden-Rossendorf and Technische Universität Dresden; Technical University of Denmark; University of Padova; Siemens Process Systems Engineering; and the Slovakia-based cement producer Cemmac. The partners will support eight fully funded PhD students conducting research into the characterisation and kinetics of carbonated materials and optimisation of the carbonation process. They will also explore the commercial opportunities for mineral carbonation. The focus will be on the carbonation of calcium-, aluminium-, and magnesium-silicates as well as cement derivatives, slag, fly ash, recycled concrete fines and mine tailings.

Denmark: FLSmidth has formed a partnership called ECoClay to develop and commercialise the technology needed to electrify the calcination of clay used in cement production. The partners include the Danish Technological Institute, US-based industrial heating specialist Rondo Energy, France-based Vicat, Colombia-based Cementos Argos and the Technical University of Denmark. The project is partly funded by the Energy Technology Development and Demonstration Program (EUDP) under the Danish Energy Agency.

The use of calcined clay in cement production allows cement producers to replace up to 30% of limestone-based clinker, resulting in up to 40% lower CO₂/t in cement produced. By electrifying the process, ideally powered by renewable sources, the ECoClay partnership expects to further reduce emissions by 10% at more uniform conditions that allow processing of a broader range of raw clays.

Based on the shared research and tests on high-temperature electric heat generation, storage solutions and renewable grid integration, the ECoClay partnership will build a pilot plant at FLSmidth’s research and development centre in Denmark. The consortium will seek to demonstrate how the ECoClay process is superior to the conventional combustion processes, has a smaller physical footprint on site and significantly lower emissions of air pollutants. According to the project plan, the ECoClay partners expect to be able to commence construction of the first full-scale electric clay calcination installation by the end of 2025.

Denmark: Engineering company FLSmidth is working with insulation manufacturer Rockwool and the Technical University of Denmark (DTU) on a research project to develop sustainable process technologies that will increase the use of renewable fuels and raw materials and reduce CO₂ emissions. The project has received a Euro2.7m grant from Innovation Fund Denmark.

The project plans to investigate and optimise high-temperature processes throughout the entire production chain in both companies. The DTU holds experience in this field from the CHEC research centre at DTU Chemical Engineering, which has focused on combustion research and emission abatement in recent years. FLSmidth plans to explore using alternative cement formulas and production methods to enable the company to launch more efficient technologies for using renewable fuels and reducing emissions. Rockwool intends to lower CO₂ emissions and reduce its fuel consumption to make its production become more sustainable.
