- Hydrogen has the largest energy density over any other fuel in the world. When we burn hydrogen in air, the reaction should be: Which means that 1mol of hydrogen can produce 286kJ energy through reaction with oxygen. Obviously, the energy density of hydrogen is E = 286 kJ/mol × 0.5 mol/g = 143kJ/g, which is much higher than that of many other fuels...
