Advantages and Disadvantages of Hydrogen Energy
6. It''s Far More Efficient Than Other Sources of Energy. Hydrogen is an efficient energy type since it can convey much energy for every pound of fuel compared to diesel or gas. This categorically means that an automobile that utilizes hydrogen energy will travel more miles than one with an equal amount of gasoline.
Hydrogen Storage | Department of Energy
How Hydrogen Storage Works. Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is − ...
