(gasoline under high temp needs more space) the hydrogen-gas must a closed system. the filler is a highpressure-vent and your gas-tank must handle -253 dregee (C) and 700 bar! pressure. BMW has a build a car "BMW Hydrogen7" that can handle hydrogen. but after 17 hours the hydrogen in the gas-tank stats to vent-out. that means a half gas-tank of hydrogen can vaporize in 9 days. the storage of hydrogen (if your not produce it on your ride) is very difficult at all. since a few years in germany the gas-stations starts upgrading that they can offer hydrogen to the costumers. the bad news is, 90% of the hydrogen manufacturing happend during fossil fuels. it's mostly natural gas here. finaly some facts about this engine-concept: since 1999 on the munich airport the company MAN drives with 3 articulated busses around the area. also in berlin in 2006 (soccer worldcup) some busses with hydrogen were used to transport people and player. the vehicles cover a distance over 8.500 km. after that success on the soccer worldcup they become a regular deployment on the berlin bus-masstransport. 2009 the project was canceled. the fixing costs raise to high. 1999 BMW build the 750hL car. the first concept car with hydrogen engine. it reaches a vmax of 225 km/h from 150kW (204hp). 2006 BMW presents at the los angeles car-show the BMW 760h "Hydrogen 7" car. as a customer and could lease the car. no buy, only lease (it's like the EV1 story pls google it if you don't know: GM EV1 - a very good e-car from 1996-1999 with many fans but rejected by oil-lobby) 2009 BMW announced to stop building cars with hydrogen engines. that takes no car of the research, so BMW is still on it.
