You are describing e-fuels. Hydrogen from excess renewables is the same idea. The critics are simply not paying attention to the fact that green energy is nearly free and therefore fuels made from it can also be nearly free.
How much will each kWh generated from synthetic fuels cost?
Can you please answer the question with dollars and cents? Or if you don't know, say so.
Green electricity isn't free. Neither will synthetic fuels be.
This is a repeat of the anti-wind and solar attacks because it is the same general principle. Basically an appeal to the unknown that the new green technology couldn't possibly be cheap, despite plenty of evidence that cost is dropping or that there is no expensive supply chain.
