Sure. There’s no doubt that today there’s an obvious advantage to BEV’s relative to FCEV’s on everything except the time involved in actually refueling (getting to a refueling station probably makes it a longer process).
The reason one might encourage hydrogen to keep plugging is in response to the possibility that a fully developed hydrogen transportation system might have more utility than a BEV system, either in whole or in part. Batteries are great at storing energy, but they’re heavy and slower to fill than hydrogen tanks. Those characteristics that make them better suited to stationary storage than transportation storage.
So when you get past physics, and into economics, that might end up mattering. We don’t know if it will! It very well might not. The cost of hydrogen will almost certainly always be higher than electricity, so unless the economies of scale that have yet to be implemented in hydrogen as a major alternative fuel supply are really high, it might not be viable. And if there were no hiccups with EV uptake once subsidies start to…subside, you might not even consider it as an alternative.
But…what if end-users don’t end up adopting EV’s like we want? What if charging time is a deal-breaker for them? What if the cost of EV’s stays stubbornly high, once the overcapacity and subsidies get squeezed out of the Chinese suppliers? Lots of what-ifs, and they may be very low probability what-ifs…but if the fate of the planet is at stake, you kind of want to have Plan B a little past the drawing board stage just in case you have to pull the trigger.
