Distributed hydrogen extraction system

摘要

A hydrogen extraction system is provided. The extraction system can comprise a compressor for compressing a gas mixture comprising hydrogen and a desulfurization unit for receiving the compressed gas mixture. The system can also comprise a hydrogen-extraction device for receiving a reduced-sulfur gas mixture and a hydrogen storage device for receiving an extracted hydrogen gas. A method of extracting hydrogen from a gas mixture comprising natural gas and hydrogen, and a method of determining an energy price are also provided.

1. A hydrogen extraction system, comprising:
a compressor configured to compress a gas mixture comprising hydrogen and output a compressed gas mixture; a selective membrane device configured to receive the compressed gas mixture from the compressor, wherein the selective membrane device includes a hydrogen selective membrane that increases a hydrogen concentration of the compressed gas mixture; a desulfurization unit configured to receive the compressed gas mixture from the selective membrane device and remove at least a portion of sulfur contained in the compressed gas mixture and output a reduced-sulfur gas mixture; a hydrogen-extraction device configured to receive the reduced-sulfur gas mixture and extract at least part of the hydrogen and output the extracted hydrogen gas; and a hydrogen storage device configured to receive the extracted hydrogen gas.
