CHN Energy, China has connected its 400-megawatt (MW) solar-hydrogen-storage project in Rudong County to the power grid as of December 31, 2024. The facility, located on tidal flats in the Yudong Reclamation Area, is China’s first offshore site integrating solar energy production, hydrogen generation, and storage technologies.
This large-scale project covers an area of 287 hectares and includes several advanced components. Among them are a 220-kilovolt onshore booster station, a 60 MW/120 megawatt-hour energy storage unit, and a hydrogen facility capable of producing 1,500 cubic meters of hydrogen per hour. The hydrogen station can also refuel up to 500 kilograms of hydrogen daily.
The project is expected to generate approximately 468 million kilowatt-hours of electricity annually. It is designed to reduce carbon dioxide emissions by 309,400 tonnes, sulfur dioxide emissions by 562.6 tonnes, and nitrogen dioxide emissions by 1,125.3 tonnes each year.
China has been increasing its focus on renewable energy projects to meet energy demand and reduce greenhouse gas emissions. In addition to the Rudong facility, the country has implemented several large-scale solar, wind, and hydrogen projects in recent years.
One example is the Tengger Desert Solar Park, which has an installed capacity of over 1.5 gigawatts (GW). Located in the Ningxia region, it is one of the largest solar farms in the world. Another major project is the Jiuquan Wind Power Base in Gansu Province, which is part of China’s 20 GW wind power program.
China is also investing in hydrogen energy, with plans for hydrogen refueling stations across the country. The government has announced goals to produce 100,000 hydrogen fuel cell vehicles by 2025, supported by facilities like Rudong. These projects reflect China’s efforts to expand its renewable energy capacity and transition toward a low-carbon economy.
