I don't think that Russia is an unreliable partner, on the contrary in fact. Anyway I'm not arguing for natural gas at all, but for syngas, which should be carbon neutral. I never said "we shouldn't diversify", however I think we should diversify towards things that work.
H2 is hyped at the moment but can only be at best a very small part of the solution. Synthetic zero-carbon methane is almost certainly more interesting because the infrastructure is already there, most things working on oil can be converted to methane, etc.
- sergeykish 6y agoIt would be great to utilize existing infrastructure. I think everyone understands that. That requires H2 and Direct air capture and Sabatier process. May work [1], I am not sure about heat recovery part, isn't heat lost in Sabatier reaction? > Heat from sabatier reaction: 7.2 - 5.6 = 1.6 kWh > Heat from electrolysis = 1.98 kWh > Total heat = 3.58 kWh > If we can recover 70% of the heat is would cover DAC heat requirement. Climeworks is interesting company — capturing CO2 at $600/tonne, now they produce natural gas [2].
