China’s Largest Integrated Solar-Hydrogen Farm Begins Operations in Jiangsu
Beijing, The Gulf Observer: The Rudong Offshore Photovoltaic-Hydrogen Energy Storage Project, China’s largest integrated solar-hydrogen farm, has officially commenced operations in Rudong County, Jiangsu Province. The project, owned by Guohua Energy Investment Co., Ltd., a subsidiary of CHN Energy Investment Group, began feeding power into the grid on December 31, 2024, the company announced in a press release on Friday.
Marking a milestone in China’s energy transition, the Rudong project is the country’s first initiative combining comprehensive energy utilization and coastal ecological management. It integrates photovoltaic power generation, hydrogen production, hydrogen refueling, and energy storage, positioning it as a leader in renewable energy innovation.
Spanning 4,300 mu (approximately 287 hectares), the project boasts an installed capacity of 400 megawatts. Key infrastructure includes a newly constructed 220 kV onshore booster station, a 60 MW/120 MWh energy storage facility, and a hydrogen production and refueling station capable of producing 1,500 standard cubic meters of hydrogen per hour and refueling 500 kilograms daily.
Once fully operational in 2025, the project is expected to generate an average of 468 million kilowatt-hours of electricity annually. This output is equivalent to saving 151,000 tonnes of standard coal per year and significantly reducing emissions, including 309,400 tonnes of carbon dioxide, 562.6 tonnes of sulfur dioxide, and 1,125.3 tonnes of nitrogen dioxide.
The Rudong project leverages Jiangsu’s unique tidal flat resources and advanced photovoltaic technology, employing intelligent control systems to maximize energy conversion and storage efficiency. By integrating hydrogen production through water electrolysis, the project enhances overall energy utilization efficiency, bolsters the regional grid’s peak-shaving capacity, and improves electricity supply stability.
“This project represents a significant step toward a more sustainable energy structure and contributes substantially to environmental protection,” CHN Energy stated.
The Rudong project exemplifies China’s commitment to renewable energy innovation, reinforcing its role as a global leader in the transition to a low-carbon future.
