The Haimen Station natural gas residual pressure power generation project, the first high-pressure pipeline project of its kind in China, has recently begun operations in Haimen district, Nantong.

This project achieves efficient utilization of residual pressure energy in high-pressure natural gas transport, representing a significant breakthrough in China's long-distance pipeline energy integration. 

"In the past, the residual pressure energy generated during natural gas pressure regulation could not be effectively utilized, resulting in some energy waste," said Li Xiao, an engineer at the State Pipeline Network Group. 

He added that the new project, which uses advanced technology, ensures normal gas transmission while generating approximately 3 million kilowatt-hours of electricity annually, which is enough to reduce carbon dioxide emissions by over 2,000 metric tons. 

Notably, the project's core equipment was independently designed and manufactured in China. It creatively uses adjustable flow-guiding technology and 3D-printed impellers, utilizing natural ventilation to efficiently reheat low-temperature natural gas, resulting in dual benefits for resource conservation and environmental protection.
