- OlympusMonds 3y agoYeah, but making lime is very energy intensive.
- mrob 3y agoIf the lifetime energy savings are greater than this energy cost then it's still a good idea. You only need a thin coating so it sounds plausible to me.
- retrocryptid 3y agoDid you read the paper?
- littlestymaar 3y agoWrong thread? (because there's no paper being discussed in this one…)
- retrocryptid 3y agoScroll up. Find the reference to the paper. Click on it. Read it.

- elmolino89 3y agoThe input substrate to produce CaO is CaCO3. This requires a lot of energy, often obtained by burning coal and the reaction releases CO2. Absorbing CaO/Ca(OH)2 makes sense only in systems like submarines/bunkers with no external air supply. As a CO2 capture method on a large scale is makes no sense. Even if we think about using CaO as some "CO2 capture and release" material with who knows, storing pure CO2 underground, I think even theoretical no CO2 emitting energy needed for baking CaCO3 has a better use.
