Providing 151 thousand tons of coal… operating the largest marine solar farm in China

China has witnessed the construction of an integrated solar and hydrogen energy farm, located in the flat coastal region of eastern China, which has recently entered into official operation.
It is the largest of its kind in China and is officially known as the Rudong Offshore Photovoltaic-Hydrogen Energy Storage Project. It was successfully connected to the electricity grid and began operations on December 31, 2024.
According to the statement, this marks the launch of the first comprehensive energy use and coastal ecological management project in China, integrating photovoltaic power generation, hydrogen production, hydrogen refueling and energy storage.

Hydrogen production station

The Rudong project has a total installed capacity of 400 MW over an area of ​​about 287 hectares, and includes a newly installed 220 kV onshore booster station.
It also includes an energy storage facility and a hydrogen production and refueling station with a production capacity of 1,500 standard cubic meters per hour and a hydrogen refueling capacity of 500 kg per day.
With full operation this year, according to Xinhua, the project is expected to generate an average of 468 million kilowatt-hours of electricity annually, equivalent to saving approximately 151,000 tons of standard coal each year.

Reducing emissions

This will result in a significant reduction in emissions, approximately 309,400 tons of carbon dioxide, 562.6 tons of sulfur dioxide, and 1,125.3 tons of nitrogen dioxide.
These reductions not only make a significant contribution to environmental protection, but also represent a major milestone for moving forward with the transition to a more sustainable energy structure.
