On December 31, 2024, the Rudong Integrated Photovoltaic (PV)-hydrogen-storage Project, operated by CHN Energy’s Guohua Energy Investment Co., Ltd. was successfully connected to grid. This groundbreaking project, located on the coastal tidal flats of the Yudong Reclamation Area in Rudong County, marks a significant milestone as China's first integrated offshore facility combining PV power generation, hydrogen production and refueling, and energy storage, all within a framework of comprehensive energy utilization and coastal ecological restoration.

The 400-megawatt project, spanning 287 hectares (4,300 mu), incorporates a newly constructed 220 kV onshore booster station, a 60 MW/120 MWh energy storage facility, and a hydrogen production and refueling station with a capacity of 1,500 cubic meters per hour and 500 kilograms per day, respectively. Part of China's third batch of Desert, Gobi and Rocky Areas Mega Wind and Solar Base Projects, the Rudong facility is expected to generate approximately 468 million kilowatt-hours of electricity annually.

The project offers substantial environmental benefits, projected to reduce annual carbon dioxide emissions by approximately 309,400 tons, sulfur dioxide emissions by 562.6 tons, and nitrogen dioxide emissions by 1,125.3 tons. These reductions would contribute significantly to local ecological protection and promote green, low-carbon development. By leveraging coastal tidal flat resources and employing advanced PV technologies and intelligent control systems, the project maximizes energy conversion and storage efficiency. Furthermore, hydrogen production via water electrolysis would enhances overall energy efficiency.

The Rudong project is poised to strengthen regional energy infrastructure by improving grid stability and peak-shaving capabilities. It will also contribute to energy structure optimization and sustainable development in Rudong County and surrounding areas.
