Project: Accelerating Carbon Capture using Oxyfuel technology in Cement production

Acronym AC2COM (Reference Number: 299663)
Duration 01/09/2019 - 31/08/2022
Project Topic Advancing the oxyfuel technology for cement industry by assessing key technical aspects to expedite the large-scale implementation of oxyfuel CO2-capture for retrofitted cement plants and promoting a novel oxyfuel concept for new-build plants. Secondary objectives include: Developing a novel oxyfuel concept, promoting this technology to the 2nd generation for new-build cement plants. Expediting 1st gen. oxyfuel technology to market by retrofitability analysis of two selected demo oxyfuel plants (ECRA CCS project) supporting technology transfer from TRL6-TRL8. Advancing 1st gen. oxyfuel technology for utilization of high shares of alternative fuels, boosting CO2 negative cement plants (Bio-CCS). Optimization of the oxyfuel cement process with the goal of lowering the CO2 avoidance cost. Guideline for the techno-economic decision-making process of retrofitting oxyfuel in cement plants. Comparative techno-economic study on 1st gen. retrofitted and 2nd gen. new-build oxyfuel cement plants
Project Results
(after finalisation)
AC2OCem will help close the knowledge gaps for future oxyfuel applications in the cement industry. The use of large shares of alternative fuels with high biogenic content opens the possibility to promote Bio-CCS and consequently potentially negative CO2 emissions. The Kiln burner of the 2nd generation oxyfuel technology is expected to positively impact the OPEX and CAPEX, so newbuild plants can benefit from this innovative oxyfuel concept. Optimized operation strategies in the calciner to avoid excessive coatings and build ups can reduce potential shut downs. Oxyfuel combustion using large shares of alternative fuels in the calciner complements the focus on developing Bio-CCS. Stakeholders in the industry will possess useful information from the techno-economic analysis in order to make strategic decisions on new CCS projects. Better and more informed decisions can be made based on the sustainability and environmental impacts of long-term CO2 capture strategies in the cement industry.
