We already transport electricity and then it is just wasted because we don’t need that much of it during peak green energy generation. You would use this otherwise wasted energy and store it in hydrogen.
You have no real argument here so you’re bringing in useless semantics. We’re already transporting and storing hydrogen in liquid form without any issues.
You have to realize just how idiotic the idea of a battery trailer is. Current, garbage batteries barely able to achieve 250 mi of range are 25% of car’s weight.
It doesn’t matter how inefficient hydrogen is to produce because we’d be using energy that is currently just wasted.
