D4.6 CEMCAP comparative techno-economic analysis of CO2 capture in cement plants

In CEMCAP, four different CO2 capture technologies for cement plants are investigated: the oxyfuel technology, the chilled ammonia process, membrane-assisted CO2 liquefaction, and the calcium looping technology. This report presents a techno-economic evaluation of these technologies. Key performance indicators such as specific primary energy consumption for CO2 avoided (SPECCA), cost of clinker and cost of CO2 avoided are calculated. The calculations are based on process simulations, with input from experimental work carried out in the project. The SPECCA of the CEMCAP technologies are all lower than 60% of the reference technology (MEA) under the defined base case conditions. The cost of clinker increases with 49-92% compared to the cost of clinker without capture. The cost of CO2 avoided is between 42 €/tCO2 (oxyfuel process) which is approximately halved compared to MEA, and 84 €/tCO2 (MAL process), which is on the same level as MEA. The techno-economic KPIs are strongly dependent on factors such as steam source, electricity mix, electricity price, fuel price, etc. For the assessment of a CO2 capture technology for a specific plant, a more plant specific techno-economic evaluation should be performed.
Changes in revision 1
Information and reference on cost and climate impact of steam import is included in Section 4.5. Oxygen flow rates are corrected in Table 6.1. Figures 9.2 and 10.2 are revised. Some other minor revisions are made in the text.
