Electrochemical Cement Process Reduces CO2 Emissions by 98%

Researchers at the University of British Columbia have developed a method to produce belite cement using electricity instead of extreme heat. By utilizing an electrochemical process at 140 degrees Fahrenheit and incorporating recycled cement waste, the team reduced carbon emissions from 800 kg to 20 kg per ton. The process also generates hydrogen gas as a byproduct, which can be used to fuel the subsequent kiln stage. This approach lowers the overall energy requirement by 70% and offers a potential path toward zero-emissions production for massive infrastructure projects like dams.
