Liquid Hydrogen

Liquid Hydrogen is a light propellant with a very high specific energy.

Engines and Tanks
Liquid hydrogen is used in plasma engines and as a working fluid for nuclear thermal engines. The problem with the use of this fuel is its very low volumetric energy density - lots of tank volume is required. A number of tanks exist for Liquid hydrogen, many of which are as a result, very large. It can be awkward to build a large vessel with hydrogen-fuelled engines, however, it is quite light to lift into orbit.
