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 ...

You’ve probably heard of the chemical calcium in milk. But calcium shows up in lots of other stuff too. For example, the hard part of your bones and teeth is made from calcium connected to a chemical ...

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 ...
