Hydrogen Energy and Fuel Cell Technology

Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution. NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit. Hydrogen fuel cells power the shuttle''s electrical systems, producing a clean byproduct - pure water, which the crew drinks.
