Seems like I've heard about H fuel cells for a long time. If superior, what is the delay to market?
This is what a quick search came up with. Seems mainly cost.
"Hydrogen fuel cell vehicles (FCEVs) are delayed primarily by a severe lack of refueling infrastructure, extremely high fuel costs, and low energy efficiency compared to battery electric vehicles (BEVs). The limited network of stations, which often experience maintenance issues or shortages, makes daily use difficult, while high production and transport costs for hydrogen make them less economical for consumers."
