Since they want to use solar/electricity to produce hydrocarbon fuels, there is no need to transport electricity. Make the fuels where the sun shines. Maybe build a pipeline or two out of the desert.
I think it might be viable for aircraft even if ground transport eventually goes all electric.

- walrus01 4y agoThey use vast amounts of seawater, storing the leftover brine, or crystallized salt in huge quantities will become a problem. Existing medium sizee drinking water desalination plants already create a huge amount of brine.
- labawi 4y agoWhy would you store it, instead of mixing it back in the sea? I guess you would need some pipes and pumps to move it away from your inlets, but that seems comparatively cheap.
- walrus01 4y agobecause shoving all that brine back into the sea in the general area of the desalination plant causes a localized ecological disaster and dead zone of marine life
- labawi 4y agoAs said, use some pipes and pumps to move it away. Don't forget to dilute (again, use pipes and pumps or whatever you prefer).
