Electrochemical decarbonization of cement production
TECHNOLOGY OVERVIEW
Designed to remove process emissions at their source
CURA has developed an electrochemical system that targets cement’s largest source of emissions: CO₂ released during limestone calcination.
Rather than focusing solely on fuel switching or alternative feedstocks, the approach addresses emissions embedded in clinker chemistry — enabling meaningful reduction while preserving existing production systems.
PROCESS EMISSIONS
Why process emissions dominate cement’s footprint
Chemical origin
When limestone is heated to form cement, CO2 is released as part of a chemical reaction. These emissions are inherent to the material itself.
Not solved by fuel switching
Electrification and alternative fuels reduce combustion emissions, but they do not eliminate process CO2.
Growing proportion of total emissions
As energy systems decarbonize, process emissions represent an increasing share of cement’s overall footprint.
Structural constraint
Without direct intervention in the calcination pathway, these emissions persist regardless of efficiency improvements.
HOW IT WORKS
Addressing emissions at the source
Electrolysis
Water is split into acid and base using electricity
Leaching
Acid is used to split limestone into calcium ions and pure CO2 for storage of utilization
Precipitation
Base reacts with calcium to produce hydrated lime, a key feedstock for Cement
Heating
Lime is combined in a raw meal mix and heated to produce Ordinary Portland Cement
