国际首套零碳复温天然气压差发电系统投运

Core Insights - The first international zero-carbon natural gas pressure differential power generation system has been officially put into operation in Qufu, Shandong, developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences in collaboration with Zhongke Jiulang (Beijing) Energy Technology Co., Ltd [1][2] - This system can generate over 3.3 million kilowatt-hours of electricity annually, achieving complete autonomy in core equipment and processes with zero carbon emissions [1] Group 1 - The system functions as an "energy recovery device," converting wasted pressure energy during the pressure reduction process into electrical energy [1] - It employs an innovative "zero-carbon reheating" technology that can raise the outlet temperature to 0 degrees Celsius in winter without burning natural gas, thus preventing pipeline freezing and eliminating the energy consumption required for traditional reheating [1] - The system not only meets the electricity needs of the station itself but also allows excess electricity to be fed into the grid, demonstrating stable and reliable operation after multiple tests [1] Group 2 - The successful development and operation of this zero-carbon reheating natural gas pressure differential power generation system can effectively promote the rapid development of natural gas pressure differential power generation technology and industry [2] - It transforms the wasted pressure in natural gas networks into substantial zero-carbon electricity, supporting the construction of zero-carbon natural gas stations and contributing significantly to China's "dual carbon" goals [2]
