Zhejiang launches a comprehensive energy demonstration project using \"green hydrogen\" on Dachen Island
Thread Content
On July 8, following adjustments by technical personnel, the **Hydrogen Energy Comprehensive Utilization Demonstration Project on Dachen Island in Taizhou, Zhejiang Province was officially put into operation. This comprehensive energy demonstration project for \"green hydrogen\" on the island serves as a model that can be used as a reference for exploring the production and storage of hydrogen from renewable energy sources in island areas, as well as the diversified integration and efficient utilization of hydrogen energy. According to explanations, “green hydrogen” refers to hydrogen produced by splitting water using renewable energy, with no carbon dioxide emissions generated during its production process. Utilizing the abundant wind energy available on Dachen Island, this project produces \"green hydrogen\" through water electrolysis using proton exchange membrane technology. It establishes a combined heat and power system that includes hydrogen production, hydrogen storage, and fuel cells, thereby facilitating the utilization of clean energy on the island and optimizing the power grid flow.
Dachen Island, located in the East China Sea, has an average annual wind speed of 6.8 meters per second, with 7,000 hours of annual effective wind energy availability, making it exceptionally rich in wind energy resources. Currently, there are 34 wind turbines in operation, with a total installed capacity of around 27 megawatts; these turbines can generate more than 60 million kilowatt-hours of electricity per year on average. “Once operational, this facility is expected to consume 365,000 kWh of excess wind energy on the island each year, and produce 73,000 cubic meters of hydrogen. This hydrogen can be used to generate approximately 100,000 kWh of electricity, thereby reducing carbon dioxide emissions by 73 tons. ”Zhang Chi, deputy director of the Internet Department at Taizhou Power Supply Company of State Grid Zhejiang Electric Power Co., Ltd., explained that this project functions like a \"large-scale power bank\", capable of providing emergency power support to Dachen Island during peak electricity demand periods or when the power grid is under maintenance.
It generates electricity as well as hydrogen – what advanced technology!
