Other solar cars use silicon solar cells with efficiencies around twenty percent.
Solar fuel cell cars.
The battery pack in a typical solar car is sufficient to allow the car to go 250 miles 400 km without sun and allow the car to continuously travel at speeds of 60 mph 97 km h.
That s almost twice as much as comparable fully electric or hybrid vehicles.
Bloom energy says it can now leverage existing cheap wind and solar electricity and a new solid oxide electrolyzer to produce hydrogen fuel that will be on par with gasoline fuel as far as costs.
Obviously if fuel cell vehicle technology does not develop and costs do not decline then fuel cell vehicles will not be economical.
Hydrogen has the same benefits of electric vehicles as they use the same electric motors more horsepower instant torque zero emissions etc while eliminating many issues derived from battery electric vehicles long recharge times limited range cold start added.
We chose relatively optimistic base cases because pessimistic cases would not be very interesting.
Heavy duty fuel cell vehicles are electric vehicles with range fueling time equal to diesels today.
