Solar cement — Solar-driven electrolysis for making lime and no CO2 emission

By Eileen De Guire / April 12, 2012

Conventional thermal decomposition of calcium carbonate for cement-making generates almost as much CO2 as lime. Solar-driven electrolysis of calcium carbonate yields calcium oxide and carbon (or carbon monoxide) and oxygen. Credit: Licht; George Washington University. Energy gurus often talk about reducing CO2 emissions. Why not be more aggressive and talk about eliminating CO2 emissions? And,…
