There is a consensus on the key role of carbon capture, utilisation and storage (CCUS) in the reduction of industrial CO2 emissions . An aggregated CO2 amount of 1.8 Gt until 2030 and 12.2 Gt until 2050 must be captured to meet ambitious CO2 reduction targets, while 40 % of those emissions cuts must take place in the European industry .
In 2016, around one-fourth of the CO2 emitted from major industries was related to cement production . Referring to previous carbon capture and storage (CCS) projects in the field of cement production, oxyfuel is identified as the most cost-effective solution, in comparison with post combustion technologies, for decarbonisation of cement plants [3, 4]. Hence, the AC2OCem project aims to contribute to the long-term European CO2 reduction target and to ac-celerate carbon capture by maturing the oxyfuel technology in the cement industry. The project investigates the existing 1st generation oxyfuel technology and an innovative 2nd generation oxyfuel concept with the ultimate goal of reducing CO2 avoidance cost, increasing plant efficiency and strengthening the overall competitiveness.
The project goals are defined based on the existing knowledge on an oxyfuel cement process obtained via previous and ongoing carbon capture projects in the cement industry. This will allow a narrowing of the technological gaps for promoting the oxyfuel technology to accelerate the large-scale demonstration with the perspective of near-zero CO2 cement production.
The project consists of six work packages, management and dissemination, advanced oxyfuel burners, optimization of oxyfuel calciner, process simulations and techno-economic studies of 1st and 2nd generation oxyfuel technologies and a life cycle assessment. Within the project, pilot-scale experiments, as well as analytical studies, will be performed to bring the key components of oxyfuel cement plants to TRL 6 with the aim of reducing the time to mar-ket of the oxyfuel technology in the cement sector.
