Concrete production makes up 8% of global CO2 emissions. Half comes from the fossil energy used to make it (which, hopefully, can transition to clean power), and the other half comes from the CO2 that escapes during the chemical transformation. David Chandler at MIT describes research there that shows how simply adding sodium bicarbonate (yes, the baking soda you put in your cookies) during the early stages of production can remove, by … [Read more...]
EEMPA solvent and CO2 mineralisation can take us one step closer to our carbon capture goals
If the models are correct that global carbon emissions will keep rising until at least 2040 then carbon capture and storage (CCS) is essential. And most of the vast amounts of CO2 we must capture wonât be âutilisedâ as itâs more than we can possibly use. So storage is an essential part of the equation, explains Jim Conca. He scopes out the problem before looking at two innovations that can bring costs down and bring the technology one step closer … [Read more...]
