For CCUS, we show that the economic feasibility is case dependent. The cost of producing blue ethanol is estimated as 656 €/t, slightly above the market value of 633 €/t. The cost per tonne of CO 2 avoided drops from 114€ (CCS) to 111€ (sugarcane-based displacement) and the amount of CO 2 avoided increases by 3%, to 0,518 MtCO 2 /y. In ...

Kiln electrification will only form one part of the possible solutions for a decarbonised cement industry. The electrified kiln would cut CO 2 emissions which would be a huge saving for EU cement producers looking at approximately EUR75/t of CO 2 emission charges. Battery storage could well be required to enhance the electric kiln …
