【Ten Years of Great Progress in Chemical Engineering Technology】083-2023: Operation of China’s First Hydrogen-Electric Coupled Medium-Voltage DC Microgrid
Thread Content
Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On June 15, 2023, the first hydrogen-electric hybrid medium-voltage DC microgrid in China, which was part of the special research and development program launched in 2020, came online in Ningbo, Zhejiang. This project has achieved full domestic production of all equipment related to the entire hydrogen industry chain, with the hydrogen-to-electricity conversion efficiency reaching a world-leading level. The project is located in the Binhai Economic Development Zone of Cixi, Ningbo, where there are abundant renewable energy resources, with a photovoltaic installation capacity of over 500 kilovolt-amps. The facility covers an area of 12,600 square meters. It is centered around a comprehensive energy management system that integrates electricity, hydrogen, and heat. The main power grid consists of ±10 kV and ±375 V DC buses. Powered by green electricity generated from 4 megawatts of photovoltaic systems and 0.2 megawatts of wind turbines, it supports the operation of a 400-kilowatt hydrogen production unit and 10 60-kilowatt DC chargers. In addition, the facility is equipped with 3 megawatt/6 megawatt-hour battery storage and 240 kilowatt fuel cells, which can provide short-term support to the power grid when it is in urgent need. The project can operate continuously offline for 168 hours, and it is capable of meeting the hydrogen refueling needs of 10 hydrogen fuel cell vehicles as well as the fast DC charging needs of 50 pure electric vehicles per day.
The Ningbo Cixi Hydrogen-Electric Coupled DC Microgrid Demonstration Project is a supporting project for the key research and development program on hydrogen energy within the power grid, namely the special project titled \"Off-grid Wind/Solar/Hydrogen Fuel Cell DC Interconnection and Stability Control Technologies\". It is also a pilot demonstration project for the construction of a new type of power system in Zhejiang Province during the 14th Five-Year Plan period. The project is led by State Grid Zhejiang Electric Power Co., Ltd., which forms a consortium of industry, academia, research institutions, and users to carry out research and development, production, assembly, and demonstration operations. By integrating hydrogen energy with renewable energy sources such as wind and solar power, and through hydrogen microgrids, it meets users’ needs for electricity, hydrogen, and heat.
