The 100 MW, which is the first phase of the 300 MW Huainan Panji coal-mining subsidence-area floating PV project in Anhui province, achieved full-capacity grid connection. China Energy Engineering Group Anhui No. 2 Electric Power Construction Engineering Co., Ltd. is serving as the EPC contractor. The project uses the water surface of a deep coal-mining subsidence area in Panji that had remained largely idle. It is planned in two phases, comprising 100 MW in the first phase and 200 MW in the second. The project includes a 220 kV step-up substation and a 330 MVA main transformer shared by both phases. Once the 300 MW project is completed, it is expected to deliver about 350 million kWh of electricity to the grid annually.
A research team from Yunnan University and Southwest United Graduate School has developed a wide-bandgap perovskite solar cell for underwater photovoltaic applications. The device has a bandgap of about 1.96 eV and achieved a certified power conversion efficiency of 16.79% under AM1.5G illumination and 34.71% under a simulated spectrum corresponding to a water depth of 10 meters. It operated continuously at its maximum power point for 1,160 hours without significant degradation, according to results published in Joule. The team also conducted field tests near Weizhou Island in the South China Sea. A 115 cm² perovskite module operated at an actual depth of 10 meters for two hours and generated 324 mWh of electricity, which was used to charge a lithium-ion battery and power an LED. Accelerated aging tests indicated a projected T80 lifetime of about 5.49 years under simulated spectral conditions corresponding to a depth of 10 meters.
Yuedong New Energy Technology has broken ground on a semi-solid-state battery pack and containerized energy storage project in Yancheng Economic and Technological Development Zone, Jiangsu province. The facility will assemble lithium-ion energy storage modules and containerized energy storage systems, with planned annual capacity of 5 GWh once completed. According to the Yancheng government, it currently has more than RMB100 million in orders on hand and plans to complete factory renovations and begin equipment commissioning in November, targeting production by the end of 2026. Its containerized systems use dual-mode liquid cooling and liquid heating thermal management, with the company claiming system conversion efficiency of at least 94%. The products are intended for utility-scale power plants, C&I energy storage and new-energy heavy-duty trucks.
Energy developer, CGN New Energy, has launched procurement for implementation-planning services for a 12 GW integrated energy project in Hulunbuir, Inner Mongolia. The planned renewable energy capacity comprises 5 GW of wind and 7 GW of solar, with coal-fired power, electrochemical energy storage, pumped hydro and concentrated solar power to be configured as part of the overall project plan. Earlier this month, CGN New Energy also launched a tender for power-source planning services for the Tengger-Badain Jaran Desert renewable energy and storage base supporting the “Inner Mongolia electricity transmission to Hubei” project. The planned base includes 4 GW of wind and 8 GW of solar. The two projects together represent 24 GW of planned wind and solar capacity in Inner Mongolia.
