A large solar-hydrogen farm in Rudong County, Nantong City, China, has started its operations, becoming the largest of its kind in the country. The farm, officially named the Rudong offshore photovoltaic-hydrogen energy storage project, covers 4,300 mu and features a 400-megawatt capacity. This project by Guohua Energy Investment Co Ltd under CHN Energy integrates photovoltaic power generation, hydrogen production, refueling, and energy storage. It aims to promote comprehensive energy utilization and coastal ecological management. The farm is expected to generate 468 million kilowatt-hours annually, saving 151,000 tonnes of coal and reducing various emissions. By harnessing coastal resources and advanced technology, including water electrolysis for hydrogen production, the project enhances energy efficiency and grid stability, contributing to a more sustainable energy future.
