PRESSURE REDUCTION SYSTEM

摘要

A system for reducing pressure and extracting energy from natural gas pipelines or the cryogenics industry comprises an electrolyser that produces hydrogen, a heating device adapted to heat the natural gas in the pipeline and a device adapted to extract energy from expansion of the natural gas, wherein the extracted energy is used to power the electrolyser and/or heat the natural gas. The system can be used to extract energy from gas expansion.
