So this process is "CO2 hydrogenation" meaning that it needs elemental hydrogen, which is not naturally available (except in trace amounts). To make this work one needs to first produce hydrogen which is itself an energy consuming process.
So basically, we'd burn fossil fuels producing CO2 and then reverse this process via "CO2 hydrogenation" (with significant losses) to again get the hydrocarbons (aka gasoline) ?
This whole thing would only make sense if we had abundant source of elemental hydrogen. But then why burn fuel in the first place.
(This would only make sense if all fuel totally ran out and then we'd need this process to make hydrocarbons for material use: plastics, etc..)
