Huaneng engineers in Zhengzhou have commissioned China's first closed-loop geothermal project utilizing supercritical carbon dioxide. This innovative approach involves circulating CO2 through a 2,500-meter well to extract geothermal heat, which is then returned to the earth. The system demonstrates improved efficiency, with reduced pumping losses and increased heat extraction capacity. AI
RANK_REASON This is a significant infrastructure project, being the first of its kind in China for commercial geothermal energy using supercritical CO2. [lever_c_demoted from significant: ic=1 ai=0.0]
