The Guohua Rudong Project integrating photovoltaic power generation, electrolysis of water for hydrogen production, and energy storage technology, is designed to generate 468 million kilowatt-hours of clean electricity. It ranks as the country's largest offshore demonstration facility of its kind.

Located on the tidal flats outside the Yudong Reclamation Area, the project brings together a 400,000-kilowatt offshore solar farm, a 60-megawatt/120-MW-hour energy storage station, and a 1,500-normal-cubic-meter-per-hour green hydrogen production system.

This integrated setup forms a complete closed-loop system for green power generation, storage, and conversion. It is expected to generate 468 million kilowatt-hours of electricity a year, translating into clean power for nearly 200,000 households.

Beyond electricity generation, the project produces 482 metric tons of high-purity green hydrogen annually. This green hydrogen is specifically supplied to the Yangtze River Delta region, and a supporting hydrogen refueling station has been put into operation at the same time, completing the entire application chain for green hydrogen.
