Solid state batteries are a step forward, probably a big one.
But they still need charging and my view is that outside the urban/suburban areas it will be another 5 years before fast chargers are everywhere.
Hydrogen is going to be a player, especially for white vans and larger.
Synthetic gasoline will be available for toy cars and their petrolheads.
Diversity is the name of the game, actually anything that does not involve fossil carbon! Diversity is good.
Tell our Government that diversity is good. They want momently everyone to buy a EV and a heat pump. The dc sources are no issue because it comes out of the plug. Mostly French nuclear power, which Germany does not want to produce, or Polish power from lignite-fired power plants. No one knows how to store our random wind power. Our Minister of Economics is a miracle of technical competence, because he has written children's books all his life.
