In Qufu, Shandong Province, the world's first zero-carbon reheated natural gas pressure differential power generation system has officially commenced operations. This groundbreaking system, a collaborative effort between the Institute of Engineering Thermophysics of the Chinese Academy of Sciences and Jiulang (Beijing) Energy Technology Co., Ltd., boasts fully independent core equipment and processes. With a maximum power output of 500 kilowatts and an annual power generation capacity surpassing 3.3 million kilowatt-hours, it sets a new benchmark in sustainable energy solutions. Utilizing an innovative zero-carbon reheating process, this system achieves the recovery of pressure differential energy without relying on external heat sources, marking a significant leap forward in eco-friendly power generation.

The Institute of Engineering Thermophysics has been at the forefront of this research since 2013. In a notable milestone, it established the nation's inaugural 300-kilowatt demonstration project in Zibo, Shandong Province, in 2021. By December 2025, the institute had successfully developed and implemented the world's first system of its kind, achieving grid-connected power generation. The operationalization of this system is poised to catalyze the advancement of natural gas pressure differential power generation technology and industry, playing a pivotal role in realizing the national 'dual carbon' strategic objectives.
