Not to mention that it requires capturing and probably liquifying the CO2 first, which is also energy intense. If we do CO2 Hydrogenation, it will be for Methane gases, not liquid. Methane is easy to store, has rather flexible uses and would help in keeping the grid stable.

Liquids, especially when used in ICE engines later on, would result in an energy efficiency of 5-10% max. This is abysmal and we could use that otherwise wasted energy to decarbonize many other things by directly electrifying them.
