CHN Energy has completed construction of a 400 MW solar-hydrogen-storage project in Jiangsu, combining coastal PV, battery storage and green hydrogen production in a single integrated system. The project, which includes a 60 MW/120 MWh battery and a hydrogen facility producing 482 tons annually, is expected to begin full operations after hydrogen commissioning in August 2026.

China Energy Investment Corp (CHN Energy) has completed construction of its Guohua Rudong solar-hydrogen-storage integrated project in Jiangsu province, marking another step in China’s efforts to combine large-scale solar generation with battery storage and green hydrogen production.

The project is located in the Yudong reclaimed tidal-flat area near Yangkou Port in Rudong county, Nantong. It is operated by the Jiangsu branch of Guohua Investment, a CHN Energy subsidiary. The company describes it as China’s largest integrated solar-hydrogen-storage project.

The facility includes a 400 MW coastal PV plant, a 60 MW/120 MWh battery energy storage system, a green hydrogen production facility with a capacity of 1,500 Nm³ per hour, and a 220 kV shore-based substation. It also features hydrogen refueling capacity of 500 kg per day.
