The authors likely didn't analyze it. It gives a value in eV, that can be extrapolated outwards though I am not exactly sure how. It would also depend on how you implement the process. However, the paper does mention the reactor is at 21 bar and 300-500C, to give you ballpark requirements for any implementation.
This likely isn't a viable CO2 reduction method. It would be if there was a massive overbuildout of green energy collection. A more likely use is a green way to make a portable power source.
It's possible to produce gasoline from CO2+extra+H and extreme heat and pressure. This seems more achievable. Such designs were, I think, using nuclear heat almost directly.

It gives values in eV, yes, and 1 eV ~= 96 kJ/mol, if you're more familiar with those units. However, what they're looking at is peaks in the x-ray diffraction spectra, indicating presence of compounds with various specific binding energies. That doesn't really tell anything about the energy efficiency of the process as a whole. > It's possible to produce gasoline from CO2+extra+H and extreme heat and pressure. This seems more achievable. Such designs were, I think, using nuclear heat almost directly. There's a whole raft of different processes to produce hydrocarbons given CO2, H2, and some energy input. Fischer-Tropsch is perhaps the most famous. This could be yet another one, if they can make it work out. If it can be more cost effective than existing approaches, it's really really awesome, but won't "save the world" by itself of course.
