BEIS has undertaken a number of studies looking at the environmental performance of hydrogen and electricity in a number of scenarios. The comparative environmental advantages of each depend on how they are produced (‘green’, ‘blue’ or ‘grey’ hydrogen and renewable or fossil fuel electricity generation) and the end use for the energy vector (for example in transport or heating applications). The studies do not differentiate between medium and long-term environmental effects.
