Abstract
An energy recovery system for an electrolyzer includes a heat engine configured to be thermally connected at a hot side to a waste heat output of the electrolyzer, and an electrical generator configured to be functionality coupled to a crankshaft of the heat engine. The energy recovery system is configured to recover electrical energy generated by the electrical generator from waste heat of the electrolyzer. A method of recovering energy, such as by use of the energy recovery system, is also provided.

1-15. (canceled)
An energy recovery system for an electrolyzer, the energy recovery system comprising:
- a heat engine being a Stirling engine having a hot side and a crankshaft, said heat engine configured to be thermally connected at said hot side to a waste heat output of the electrolyzer;
- and
- an electrical generator configured to be functionally coupled to said crankshaft of said heat engine;
- the energy recovery system configured to recover electrical energy generated by said electrical generator from waste heat of the electrolyzer;
- and
- the energy recovery system configured to input the recovered electrical energy to the electrolyzer.
A method of recovering energy, the method comprising:
- (i) collecting waste heat from an electrolysis process;
- (ii) using a heat engine and an electrical generator to transform the collected waste heat into electrical energy;
- and
- (iii) inputting the recovered electrical energy into an electrolyzer to drive a related auxiliary system of the electrolyzer.
