Abstract
The hydrogen gas compressor system (104, 108, 112) comprises a hydrogen gas storage unit (502) that defines an internal volume for storing hydrogen gas. An operating fluid delivery means (514) such as a pump delivers an operating fluid to the hydrogen gas storage unit (502). This causes the pressure of the hydrogen gas contained within the hydrogen gas storage unit (502) to increase. A coolant fluid delivery means (524) such as a pump delivers a coolant fluid to the hydrogen gas storage unit to absorb heat from the hydrogen gas.
Claims18
A hydrogen gas compressor system comprising:
- a hydrogen gas storage unit defining an internal volume for storing hydrogen gas;
- an operating fluid delivery means arranged to deliver an operating fluid to the hydrogen gas storage unit in response to hydrogen gas being withdrawn from the hydrogen gas storage unit to increase the pressure of hydrogen gas contained within the hydrogen gas storage unit;
- and
- wherein the hydrogen gas storage unit comprises a coolant fluid circuit traversing through the internal volume in which the hydrogen is stored and wherein the hydrogen gas compressor system comprises a coolant fluid delivery means arranged to deliver a coolant fluid to the internal volume of the hydrogen gas storage unit to absorb heat from the hydrogen gas, the hydrogen gas compressor system being a multi-stage hydrogen gas compressor system, and wherein the multi-stage hydrogen gas compressor system is configured to, at each stage, deliver an operating fluid to the hydrogen gas storage unit to increase the pressure of hydrogen gas contained within the hydrogen gas storage unit.
A hydrogen gas delivery system having a hydrogen gas compressor system.
A method of delivering compressed hydrogen gas compressed by a hydrogen gas compressor system from a hydrogen gas production site to an end consumer, the method comprising:
- (i) operating the hydrogen gas compressor system to generate compressed hydrogen gas, the hydrogen gas compressor system including
- a hydrogen gas storage unit defining an internal volume for storing hydrogen gas;
- an operating fluid delivery means arranged to deliver an operating fluid to the hydrogen gas storage unit in response to hydrogen gas being withdrawn from the hydrogen gas storage unit to increase the pressure of hydrogen gas contained within the hydrogen gas storage unit;
- and
- wherein the hydrogen gas storage unit comprises a coolant fluid circuit traversing through the internal volume in which the hydrogen is stored and wherein the hydrogen gas compressor system comprises a coolant fluid delivery means arranged to deliver a coolant fluid to the internal volume of the hydrogen gas storage unit to absorb heat from the hydrogen gas, the hydrogen gas compressor system being a multi-stage hydrogen gas compressor system, and wherein the multi-stage hydrogen gas compressor system is configured to, at each stage, deliver an operating fluid to the hydrogen gas storage unit to increase the pressure of hydrogen gas contained within the hydrogen gas storage unit;
- (ii) delivering the compressed hydrogen gas to a hydrogen gas fuelling site, and
- iii) using a fuel compressor system to deliver the compressed hydrogen gas stored at the hydrogen gas fuelling site to the end consumer.
