WebThe main engines were powered by combining oxygen and hydrogen in the highly exothermic reaction. 2H 2 + O 2 ⇌ 2H 2 O. The fuel was stored in that brown tank in liquid form as liquid oxygen (LOX) and liquid hydrogen (LH2). Liquids are much more dense than gases, so storage in the liquid phase allows the shuttle to carry an immense amount of fuel.
