The Haber Bosch reaction does not produce any CO2:
N2 + 3H2 -> 2NH3
The challenge is getting the zero emission Hydrogen. The process presented here is somewhat better than using electricity for the electrolysis split water, but still substantially more expensive than the gray Hydrogen obtain by cracking Methane gas and releasing the CO2.
- pfdietz 3y agoWhere did you conclude it was somewhat better than using electricity for electrolysis?
- cornholio 3y agoI took the author's claim of 100% electrolytic efficiency at face value and contrasted with typical water electrolysis efficiencies, followed by a Haber-Bosch step. This method of direct electroreduction should not confused with the Laser-induced method discussed elsewhere in the thread, which has abysmal numbers.
- pfdietz 3y agoThe 100% efficiency is faradaic efficiency, not energy efficiency, I believe.
