But above all, the Energy Observer demonstrates the immense advantage that hydrogen has over batteries. The battery set weighs 1,400 kg for 112 kWh, whereas the hydrogen storage and fuel cell together weigh a total of 1,700 kg for 1,000 kWh. This means 1 kWh weighs 12.5 kg when stored in batteries, and only 1.7 kg when stored as hydrogen.
