 It's true that uranium has an extremely high energy density, which is of great importance for mobile power plants; however, nuclear fission has a lot of safety issues, especially for mobile power, which is why it is used only for stationary power plants and large military vessels, such as aircraft carriers and subs.
 Hydrogen is pretty good when highly compressed so as to get high energy volume density as well, but that leads to problems too.  Also, hydrogen leaks more easily than almost anything else.  That is especially a problem for an extremely flammable gas.  On the plus side for hydrogen, nothing burns more cleanly.

	The stated value of 76'000'000 MJ (76 Terajoules) per kg Uranium corresponds roughly to the energy released by the fission of U-235 nuclei of 202.5 MeV or 3.24·10-17 MJ per nucleus [[https://en.wikipedia.org/wiki/Nuclear_fission#Output]]. One kilogram of pure U-235 would release about 83 Terajoules. In a real nuclear power plant more energy is generated due to breeder reactions, so that per kg U-235 about 128 TJ are produced. One kilogram of natural uranium has about 0.71% U-235 and therefore the potential to produce about 910'000 MJ in a usual nuclear power plant. A fuel rod as used in a nuclear power plant (enriched to 3.5% U-235) has the potential to produce about 4.5 TJ. --[[Special:Contributions/162.158.150.231\|162.158.150.231]] 01:19, 18 March 2016 (UTC)		The stated value of 76'000'000 MJ (76 Terajoules) per kg Uranium corresponds roughly to the energy released by the fission of U-235 nuclei of 202.5 MeV or 3.24·10-17 MJ per nucleus [[https://en.wikipedia.org/wiki/Nuclear_fission#Output]].
