If somebody could figure out how to “manufacture”/mass-produce hydrogen in both a cost-effective and energy-efficient manner, I’d be all for this. But instead this is a typical Democrat move: implement (which often involves the words require/demand/enforce) a “solution” before any of that feasibility groundwork has been established.
after all, every little bit helps, like how one volcanic eruption cancels out all the vehicle emissions standard efforts for all time within one hour of spewing poison gas
