Taizhou Dachen Island Hydrogen Energy Comprehensive Utilization Demonstration Project
Thread Content
The Taizhou Dachen Island Hydrogen Energy Comprehensive Utilization Demonstration Project is the first demonstration project of hydrogen energy comprehensive utilization designed for island environments; it came online in July 2022. The project utilizes the abundant wind power on the islands to produce hydrogen through electrolysis of water, serving as an important model for hydrogen production and storage using renewable energy in China, as well as for the diversified integration and efficient utilization of hydrogen energy.
The project achieves this by establishing an integrated energy utilization system of \"renewable energy-based hydrogen production – hydrogen storage and transportation – hydrogen fuel cell combined heat and power generation\", which provides efficient, reliable, and stable power supply. Once the project is operational, it 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. It is understood that this project utilizes equipment such as integrated hydrogen production/power generation conversion units, achieving breakthroughs in energy management and safety control technologies for the comprehensive utilization of hydrogen in China. It enhances the adaptability of the new power system to new energy sources, representing a significant exploration and practice in the development of such systems. The operation of the green hydrogen project will also resolve the long-standing issue of \"excess wind energy\" on Dachen Island. Dachen Island, located in the East China Sea, boasts unique wind energy resources. However, the wind energy resources on Dachen Island have long been mismatched with the electricity demand. At night (23:00–07:00 the next day), the excess wind power generated cannot be stored, and during peak electricity demand periods during the day, power is often insufficient. The operation of green hydrogen projects enables the storage of hydrogen produced from excess wind energy at night to be used during periods of high electricity demand during the day. The hydrogen storage capacity of the 200 Nm3 (standard cubic meters) hydrogen storage system is sufficient to enable the hydrogen fuel cell power generation system to operate continuously for approximately 2.5 hours, thereby enhancing the grid’s ability to maintain a stable power supply and ensure continuous power delivery.
Was it the Chiang Kai-shek forces who launched a surprise attack on Dachen Island during the Korean War?
