Yeah. You need at least as much energy to turn co2 into carbon (and oxygen) as you got from burning it in the first place. Scrubbing coal powered plants takes

Scrubbing coal powered plants takes away the whole point of the coal plant because you end up with negative energy.
- yesco 8y agoWhy would they even need to turn it back? I'm sure some of it might be salvageable but I thought the point was more towards just containing it.
- worldsayshi 8y agoContaining a yearly supply of tens of giggatones of a gas that has very little commercial value seems orders of magnitude less practical than actually avoiding producing that gas in the first place.
- Klapaucius 8y agoThat's what geological storage is all about. After all, the carbon came from the ground in the first place.
- worldsayshi 8y agoThe coal came from the ground. Not the carbon-dioxide. Not saying that it's impossible or even impractical to store co2 underground. It just seems like a proposition that has a lot to prove.
