Thank you, whenever these articles come out, people forget CO2 IS the lower energy state and while these catalysts can help, you still need energy to supply the H2...which requires you to burn coal/gas which makes CO2. It's not like there's a "CO2 always increases with every reaction" law like the 2nd law of thermo, but it isn't easy otherwise we'd all be doing that as it would be a hell lot easier to do that than the other things we need to do to combat climate change. Burning organic anything makes water and CO2, amongst the most stable (read lower energy) chemicals in the world. If you want to break one of those up, you need to increase entropy some other way, and unless we're talking solar, wind, or nuclear energy, you're going to have to make more water and CO2 (burn more coal) to do it.
