Towards decarbonization of cement industry: a critical review of electrification technologies for sustainable cement production

Abstract

Cement production accounts for 8% of global CO2 emissions, necessitating its deep decarbonization. This paper reviews: (i) electrolysis-based methods to produce cement precursors, and (ii) electrified process heat technologies, along with heat storage approaches. We highlight scaled-up calciner and kiln designs and the associated technoeconomic factors. Addressing renewable energy intermittency, and the need for grid upgrades and strategic infrastructure investments are critical to enabling the transition to low-carbon cement manufacturing.
