With the recent advances of turning CO2 into other substances, such as propane, should we be focusing more on closing the carbon cycle and simply be producing fossil fuels from the waste products of yesteryear?
Naively, it feels like we understand C, O and H, better than we understand some of the rare metals we're now introducing in the name of climate change.
Capturing CO2 and converting CO2 to fuel requires putting the energy back into the molecules somehow. That requires a ton of energy. So either way don't we need to solve electrification?
