Thanks TristanC
So indeed "if pans out" it could be handy by-product process, for a use for the daily excess power generation. (Say like the solar panel making electricity in the middle of the day, when nobody wants it, or from a wind generator in the middle of the night, when nobody wants it, or a coal fired plant, that cannot be slowed, producing power when nobody wants it, or a old nuclear plant, which too over produces for a significant time each day.)
The process would never make sense as a stand alone enthalpy.
But from a climate science view, what is you perspective?
To me it would be taking carbon dioxide from the atmosphere's already strained CO2 sources, and converting it into C2H6O. That ethanol to be broken down in a combustion process (car engines) releasing CO2 into the atmosphere once more.
Would it be carbon neutral from a climate change perspective. [Again assuming power generation is fixed and exogenous to the narrower perspective]
