Concrete Chemicals
Support programme Guidelines on State aid for climate protection, environmental protection and energy (KUEBLL)
The flagship project Concrete Chemicals is regarded as the first milestone in the decarbonisation of the cement industry. The strong project partners from industry and research – including the renewable energy company ENERTRAG, the global building materials manufacturer CEMEX and Sasol ecoFT, a leader in the development and application of Fischer-Tropsch (FT) technology – are paving the way towards more climate-friendly cement production by converting CO2 into renewable chemical products and synthetic fuels.
The EU has set itself ambitious targets to overcome the challenges of climate change: Politicians and industry are aiming for a climate-neutral economy by 2050. As part of the cement industry, CEMEX is also pursuing the ambitious goal of reducing its CO2 emissions and becoming climate-neutral by 2050 at the latest.
Rüdersdorf
The cement plant in Rüdersdorf is one of the most efficient plants in Europe. Not least for this reason, the global building materials manufacturer CEMEX has chosen this location to test and promote innovative technologies to achieve climate neutrality. The technological findings from the Rüdersdorf ‘Carbon Neutral Alliance’ are to be gradually applied in all CEMEX cement plants and adapted to the respective local conditions in order to accelerate the achievement of climate targets by decarbonising the entire cement production process. CEMEX has set itself the goal of transforming the plant in Rüdersdorf into the first climate-neutral cement plant by 2030.
Project profile
| Location: Rüdersdorf |
| Performance class: PtL plant for the production of synthetic aviation fuels, 40 kt/a |
| Commissioning: Q3/2028 |
| H2 quantities: ca. 18.000 t/a |
| Supply concept: H2 pipeline and on-site generation |
"We have developed our knowledge in the areas of sector coupling and hydrogen production not only through our experience of operating our electrolysis plant for several years, but also through active participation in several research and innovation projects. Now we are bringing this knowledge to drive the energy transition in sectors that are difficult to decarbonise and help build a market for green hydrogen."

Chairman of the Supervisory Board, founder of ENERTRAG SE, nuclear physicist & engineer
Objectives
The project partners have set themselves the goal of developing and using highly innovative and recyclable catalytic material systems to enable the production of green hydrocarbons from industrial waste gas emissions. In particular, the utilisation of CO2, but also CO and H2, will ensure that the overall efficiency can be increased by 50 percent compared to previous processes.
In addition, the consortium is driving the development of innovative catalytic processes fuelled by renewable energy to produce climate-neutral raw materials on an industrial scale. In this way, the cost efficiency of the technology can be demonstrated while using less critical materials.
