Hydrogen

Hydrogen pipelines are a lot cheaper and simpler to build than high-voltage powerlines.

And you are just ignoring what I just wrote and substitute outright lies from BEV companies. Again, there is no difference in CO2 emissions when both are made from fossil fuels. As a result, BEVs are not any greener and arguably much worse when you look at certain factors related to weight and battery production. The entire argument over efficiency is just a extremely rare scenario which doesn't even apply in this case, and won't apply even in the future. In reality, you will need to store electricity in a 100% renewable grid. That requires large scale and long-duration energy storage solutions. One of which is hydrogen based energy storage. So you will charge your BEV with hydrogen power in the future. This quickly kills the idea that BEVs are anymore efficient.

And that is before you factor future innovation. In the long run, we will make hydrogen directly, such as from photocatalysts or thermal processes that don't use electricity. Fuel cells will increase in efficiency until they are basically the same as conventional batteries. As a result, this entire argument will be totally rejected. It will only be remembered as this BEV propaganda statement from the early 21st century.
