Hydrogen vs. Battery Electric Cars

I can't believe you fell for the "what if everyone plugged in their electric car at the same time?" argument. First off, that is just not going to happen. The uptake of BEVs is very gradual, leaving plenty of time for upgrades to the power grid where necessary. Most utilities are ready for the transition, knowing that 99% of charging happens overnight when demand is low. Hydrogen requires more electricity than BEV. Oil refining requires unreal amounts of electricity, in addition to the fossil fuel emissions of ICE. Vehicle to grid technology will allow utilities to not only keep up with demand, but the added, instantly available electricity will help utilities to better manage peaks in demand.
It's a very old, long debunked argument that I wish would just go away.
