Claim 18:
19. An energy storage system comprising:
an input to receive input energy;
a compressor arrangement configured to use the input energy to compress air or other process gas to produce a compressed process gas;
a compressed gas output configured to output the compressed process gas to a compressed process gas store;
a hydrogen production apparatus which is configured to produce hydrogen;
an expander arrangement configured to receive compressed process gas from the compressed process gas store and to expand the compressed process gas to generate output energy;
an output to output generated output energy;
a heat transfer apparatus configured to transfer heat from the process gas, before the process gas is stored as a compressed process gas, to the hydrogen production process; and
wherein the hydrogen production apparatus is configured to use the transferred heat.
