This would actually provide me enough gas each week with my hybrid in office schedule.

that'd get my small cc bike filled up for my use.
I wonder is a scaled up version of this could work for grid-scale medium length storage. Smoothing out weeks of dunkleflaute is the main blocker to going to a primarily renewable grid. Gasoline is a lot easier to store than hydrogen and large scale gasoline generators should get close to the efficiency of natural gas peaker plants.
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.

Sell these to the "but mah vroom vroom noise" crowd and switch everything to electric.

So power to x, basically
But smaller
Reusing the co2 in the air. Its a good idea.
No it's not a good idea.
It's extremely inefficent compared to just using elecricity directly for whatever you're planning to do with it.
The extension cord won't reach my Airbus
Still a good idea for specific cases though. An example from current news close to me: We have line ships on lake Zürich that can't be electrified because either they are too old to sustain a major internal rework or, for some, they can't carry the battery weight.
For a case like that I'd prefer if they put some CO2 capture stations up to keep running the ships rather than scrapping them prematurely.
... if the capture stations work, that is. Can't trust the word of a startup too much.
All the catches
