Abstract
A hydrogen dispensing system includes a hydrogen storage tank for storing hydrogen gas, a turboexpander generator fluidly connected to the hydrogen storage tank, and a dispenser fluidly connected to the turboexpander generator. The turboexpander generator receives a flow of the hydrogen gas from the hydrogen storage tank at an inlet of the turboexpander generator, reduces a pressure and a temperature of the flow of hydrogen gas, and outputs the hydrogen gas to the dispenser.
Claims19
A method comprising:
- receiving, at an inlet of a turboexpander generator, a flow of hydrogen gas from a hydrogen storage tank, wherein an electric chiller is fluidly connected to the turboexpander generator between the hydrogen storage tank and the turboexpander generator, the electric chiller configured to cool the flow of hydrogen gas;
- reducing a pressure and a temperature of the hydrogen gas with the turboexpander generator;
- and
- outputting the hydrogen gas from the turboexpander generator toward a hydrogen dispenser.
