Yeah, it's going to be a long time before we can get completely away from hydrocarbon fuel. There's nothing that comes close for energy density for something that is practical to use. (Hydrogen beats it considerably but comes with a million headaches. There's a reason SpaceX doesn't use hydrolox engines despite their considerable performance advantage!)

Thus we should be looking for efficient ways of turning clean energy into hydrocarbon fuel.
