Grid scale storage doesn’t strike me as an area of application where high energy density is important, so wouldn’t batteries with less conversion loss do an overall better job? I think grid scale Lithium-ion battery stores have become somewhat common.
I’d see gasoline from CO2 capture of interest more for airplanes, drones, ships, maybe even certain modes of long haul terrestrial transport where weight and volume is important.
I could see this being useful in places where day/night cycle is skewed to prolonged periods of each. Or perhaps holding excess power from summer into winter since days are so much shorter.
But yeah, this doesn’t really seem like the best way to store grid power.
