Still a lot of bugs to work out on fuel cells. I'm close to a site with over 300 trucks running on fuel cells. They brought the warehouse to a standstill when they were first introduced. Repairs could not be made fast enough to keep the fleet going. The Fuel cell "brochure" touted them as longer lasting, faster charging and less maintenance than lead acid. In fact, they take longer to recharge than battery changes, they don't last a full shift and require far more maintenance than lead acid batteries, lasting only 100 hrs between service. Noise from fans is a big issue. They are sensitive to dust and debris getting inside. A constant stream of transport trucks have to refill huge tanks as The hydrogen is produced in another province. It's very expensive to go green, but I thought Batteries were already green? I think the Europeans are smart enough to wait until hydrogen is perfected before changing over !
