Electrochemical process that bypasses limestone could slash cement’s huge carbon footprint
Gigaton-scale carbon reductions offered by process that makes use of carbon-free calcium silicates from abundant minerals and recycled concrete
Researchers in the US have designed an electrochemical route to electrify and decarbonise cement production. The process, which generates calcium carbonate without relying on limestone decomposition, should be relatively simple to integrate into existing industrial production systems.
