CHN Energy has completed its Rudong integrated solar-hydrogen-storage project in Jiangsu (China), comprising a 400 MW PV plant, a 60 MW/120 MWh BESS, and a green hydrogen facility with a capacity of 1,500 m3/hour (CHN Energy press release, 15/06/2026). Scheduled to reach full commercial operations in August 2026 upon completing hydrogen equipment commissioning, the unified system previously achieved grid connection for its PV section in April 2025.
To power the 482 t/year hydrogen site, a dedicated submarine cable connects it directly to the PV plant, which is designed to generate 468 GWh/year, enough to supply nearly 200,000 households. Upon full deployment, these joint solar, hydrogen, and storage installations should create a closed-loop energy system that converts green electricity into green hydrogen.
This project is part of China’s third batch of large-scale renewable bases. According to Enerdata’s Global Energy Research, China’s total installed capacity reached 3,891 GW at the end of 2025, of which solar accounted for about 30% (1,202 GW).
