I've had the opportunity to drive a Hydrogen fuel cell car and here are a few quick takes: * The carbon footprint is likely larger than a Tesla but smaller than a comparable gasoline vehicle. * The cost of fuel is currently several times higher than gasoline (normalized for driving distance) which is why all the major hydrogen carmakers are giving away 3 years of fuel for free. This likely doesn't help the carbon footprint. * It takes a little longer to refuel than a gasoline car (few minutes) but less time than an electric car. * Range depends on environmental conditions and driving habits. As it is a hybrid, nonfreeway driving in stop/go traffic appears to be most efficient (this is where you get the 300+ mile range). Otherwise, in the freeway, in the mountains (uphill) and when the A/C or heater is on at full blast, be prepared to lose up to 30% of range. * There aren't as many fuel stations yet so it is a good habit to check station status online and refuel before the tank gets too empty. Stations in the USA are currently open to the public in California and a few places in the Northeast. * Some models have little trunk space as quite a bit of volume as been reallocated to the hydrogen tanks. * Some jurisdictions may require periodic (~yearly) tank inspections. * The vehicles generally handle like an electric (or hybrid in electric mode) vehicle.
