A groundbreaking solar-hydrogen energy farm in Rudong County, Jiangsu Province, China, has begun operations, making it the largest of its kind in the country. The Rudong offshore photovoltaic-hydrogen energy storage project is a comprehensive energy project integrating photovoltaic power generation, hydrogen production, hydrogen refueling, and energy storage. With a massive total installed capacity of 400 megawatts, the project is expected to produce 468 million kilowatt-hours of electricity annually, resulting in significant energy savings and emission reductions. By harnessing coastal tidal flat resources and utilizing advanced technology, including water electrolysis for hydrogen production, the project enhances energy utilization efficiency and contributes to stabilizing the electricity supply. The project's environmental impact is remarkable, with substantial reductions in emissions, such as carbon dioxide, sulfur dioxide, and nitrogen dioxide. This initiative by CHN Energy signifies a crucial step towards a more sustainable energy structure in China.
