Spreading crushed rocks on fields can absorb CO2 from the air – now chemists have devised a way to turbocharge this process ...

Stanford researchers developed a scalable method to permanently remove CO2 from the atmosphere using heat-activated minerals.

So, if we have calcium carbonate and we heat it, it breaks down to produce calcium oxide and carbon dioxide. Gethin: OK, I know you're poised with your pen and your flip chart. But, before that ...

Their novel electrochemical process can store carbon dioxide in water with the power of solar or wind, while also producing by-products such as green hydrogen and calcium carbonate – perhaps the ...
