Lastly, PV can drive electrolysis apparatus. The practical is somewhat lower yet still useful. There is fairly good evidence that methane or natural gas is not a fossil fuel. They claim that it's being continuously produced deep in the earth. There main evidence is that the deeper they drill the more abundant it becomes.
Petroleum fuels become scarcer as the depth increases.
Electric transportation improvements help all the technologies. You are comparing apples and oranges. I have to add that the technical efficiency of any solar process is of little concern since generally the energy source is for free. I hope we will eventually see these cells. This will improve the bottoming thermal cycle for the system.
