I agree with another posters comment: A Fuel Cell Plug in Hybrid is basically a "Duel Fuel" vehicle, allowing increased flexibility and range. People with Solar installed could fill up at home, or at charging stations, or at work if employers were incentivized to install plugs. Rooftops, Parking lots and adjacent grass fields or walkways could be covered in Solar to power plug ins or power on site Hydrogen Production in Industrial areas. Someday, on site Hydrogen powered by Solar will be possible for residential locations. They are doing it now in Sweden.
