Background
Oxy-fuel combustion stands as a promising carbon capture (CC) technology to significantly reduce CO2 emissions from the production of cement, but further investigations and demonstration activities are required to develop the oxy-fuel cement process to maturity.
Production of cement is a significant global industry that accounts for almost 8 pct of current global CO2 emissions. The production of cement requires temperatures of up to 1000 degrees, and the heat is mostly generated by combustion of fossil fuels. Implementing an oxy-fuel combustion as a CC technology in cement production can ensure a more effective process for cement production as wells as an economically viable and highly effective process for carbon capture and storage (CCS) compared to other end-of-pipe technologies.
Objectives
This project will reduce the risks within the oxyfied calcination process, computer simulations and the pilot reaction studies and pave the way for the first largescale industrial unit and accelerate the decarbonization of cement sector and make concrete a CO2 negative product as well as provide a basis for the market possibility of upgrading the CO2 from cement plants o e.g., methanol by combining with hydrogen from electrolysis.
The project will help develop the oxyfuel cement technology and therefore offer a product with large international potential, which can contribute too significant global CO2 reductions.
- Mature oxyfuel cement plant technology so that tests on full scale cement plants can be done.
- To develop an oxyfuel pilot calcination reactor based on process simulations and combustion studies.
- Develop digitalization technologies (simulation, control, and optimization) for CO2 emission free cement production.
- Validate potentials of the different technologies and analysis of supply chain effects.
