Hydrogen and Fuel Cell Technologies Program: Storage
Hydrogen has a very high energy content by weight (about three times more than gasoline), but it has a very low energy content by volume (liquid hydrogen is about four times less than gasoline). This makes hydrogen a challenge to store, particularly within the size and weight constraints of a vehicle. A light-duty fuel cell vehicle will carry
