[Ocean New Energy] Distributed hydrogen-electricity coupling experimental shelter put into operation in Quzhou, Zhejiang

Thread Content

On July 13, Zhejiang Province’s first distributed hydrogen-electricity coupling experimental cabin was put into operation in Quzhou. By establishing an experimental cabin for mutual conversion and efficient collaboration of hydrogen energy and electric energy, it explores and promotes on-site consumption of distributed new energy, provides a good demonstration for clean energy application scenarios in Quzhou City, and is also an effective practice for State Grid Quzhou Power Supply Company to explore the construction of new power systems. Quzhou Power Grid has a high proportion of new energy, especially the proportion of photovoltaic installed capacity, which ranks among the top in Zhejiang Province. How to realize on-site consumption of new energy and improve the stable utilization efficiency of new energy? State Grid Quzhou Power Supply Company innovatively implemented the hydrogen-electricity coupling experimental cabin project. The experiment broke through the development limitations of renewable energy and promoted the interconnection of multiple energy modes and the deep integration of source, grid, load and storage. The hydrogen-electricity coupling experimental cabin takes hydrogen energy storage technology in the field of new power systems as an entry point to carry out research on distributed coordination and optimization of source, grid, load and storage, and explores the centralized control, management and deployment of multiple energy sources, laying a solid foundation for the application of hydrogen energy storage technology in the power system. It will be widely used in scenarios such as distributed power supply guarantee, grid peak shaving and valley filling, and user-side energy storage. In order to promote the rapid implementation of experimental projects, State Grid Quzhou Power Supply Company took the "Party Building +" Engineering Secretary Project as the starting point, the provincial service innovation platform as the carrier, and the "Provincial Doctoral Innovation Station" through school-enterprise industry-university-research innovation cooperation to form a Futeng science and technology innovation team, giving full play to the backbone role of university doctors and power craftsmen, actively carrying out new power system technology innovation activities, improving the ability of collaborative innovation, integrated innovation, and cross-border innovation, and constantly stimulating employees' innovation momentum. “At the current experimental stage, the shelter is equipped with 10 kilowatt photovoltaic panels and three new energy vehicle charging piles. The solid hydrogen storage tank can store 35 cubic meters of hydrogen and can charge five new energy vehicles at the same time. ”Xu Yonghua, the project leader, said, “After this successful operation, we will further explore the industrial transformation of the results of the hydrogen-electricity coupling shelter experiment to achieve promotion and replicability. ”
