Hydrogen turboexpander-generator

A hydrogen turboexpander-generator or generator-loaded expander for hydrogen gas is an axial flow turbine or radial expander for energy recovery through which a high pressure hydrogen gas is expanded to produce work used to drive an electrical generator. It replaces the control valve or regulator where the pressure drops to the appropriate pressure for the low-pressure network. A turboexpander generator can help recover energy losses and offset electrical requirements and CO2 emissions.
