Group 1 - The "New Tian Gong Kai Wu - Technology Achievements Release Conference" focused on breakthroughs and industrial applications in China's energy sector, highlighting three key technologies: ocean blue energy technology, thermal pyrolysis technology for retired new energy components, and a new energy power generation forecasting system [1] - The ocean holds significant renewable energy potential, with global wave energy theoretical totals reaching several terawatts (TW). The friction nanogenerator (TENG) technology developed by the Beijing Institute of Nanoenergy and Systems provides a solution to efficiently capture low-frequency and irregular ocean energy [1] - A prototype of the ocean buoy, based on TENG technology, has been demonstrated at sea, providing stable power for marine IoT devices and environmental monitoring buoys [1] Group 2 - The thermal pyrolysis system for retired new energy components has been widely applied across more than ten provinces in China, achieving an annual processing target of tens of thousands of tons of retired components, validating the engineering stability and economic viability of the technology [2] - The new energy power generation forecasting system developed by Shenzhen Energy Group enhances the accuracy of site-level meteorological predictions by 15% and wind power forecasting accuracy by 10%, significantly improving the foresight and scientific basis for grid dispatch decisions [2] - Each 1% improvement in forecasting accuracy can yield substantial economic and system safety benefits, as stated by a professor from South China University of Technology, emphasizing the integration of advanced meteorology, big data analysis, and artificial intelligence algorithms in the system [2]
