China's largest offshore solar-hydrogen project connects to grid

It also has an energy storage feature.

CHN Energy has announced that its 400 megawatt (MW) Rudong integrated photovoltaic (PV)-hydrogen-storage Project has been connected to the grid on 31 December 2024.

The project is located on the coastal tidal flats of the Yudong Reclamation Area in Rudong County. It is China’s first integrated offshore facility combining PV power generation, hydrogen production and refueling, and energy storage.

Spanning 287 hectares, the Rudong facility incorporates a newly constructed 220 kilovolt onshore booster station, a 60 MW/120 megawatt-hour 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.

The project is expected to generate approximately 468 million kilowatt-hours of electricity annually. It is also projected to reduce annual carbon dioxide emissions by approximately 309,400 tonnes, sulfur dioxide emissions by 562.6 tonnes, and nitrogen dioxide emissions by 1,125.3 tonnes.
