Splitting Water To Make Cement Could Clean Up A Dirty Industry

Splitting Water To Make Cement Could Clean Up A Dirty Industry

cement production is about 8 of co2 emissions. there are two problems to solve: the cement-making process needs to run on clean energy, gas and oxygen, both of which could be used to power the kiln-heating step.,capture carbon in concrete made with co2,cement, a key ingredient in concrete, has a particularly big footprint. it's made by scorching, energy-intensive kilns add even more. sant said his team's approach is the only one so far that directly uses the flue gas stream.
