On November 13, 2021, the preliminary design of the 200MW/800MWh hydrogen energy storage power generation project in Zhangjiakou, Hebei was held in the China Petroleum Pipeline Design Building and passed the review successfully. This means that China Hydrogen Energy has taken a substantial step in large-scale energy storage peak shaving application scenarios.

It is understood that the Zhangjiakou 200MW/800MWh hydrogen energy storage power generation project is a 220kV hydrogen energy storage power station with an installed capacity of 200MW/800MWh, equipped with two 240MVA main transformers, and grid-connected power generation at a voltage of 220kV. Among them, the entire power generation area is composed of 80 sets of 1000Nm3/h large-scale electrolyzed water hydrogen production device, 96 sets of hydrogen absorption and release metal solid hydrogen storage device, 384 sets of 640kW fuel cell modules, and large-scale hydrogen production and hydrogen storage with inverter and booster electrical equipment. ,Power system.

The Zhangjiakou 200MW/800MWh hydrogen storage power generation project has a static investment of about 3 billion yuan. The project construction period is 2 years. It is expected to be fully operational in 2023. It is currently the world's largest hydrogen storage power generation project. It is reported that the project involves domestic leading technologies such as renewable energy power generation and peak-shaving power for electrolyzed water hydrogen production technology, metal solid hydrogen storage technology and fuel cell power generation technology. It is a low-carbon environmental protection project for the use of renewable energy and the application of hydrogen energy. .

Hydrogen energy storage is one of the effective solutions to the problem of renewable energy consumption. Its development and utilization are of great significance to the large-scale utilization of renewable energy. The Zhangjiakou 200MW/800MWh hydrogen storage power generation project will greatly promote the development of the hydrogen storage industry. Development and provide a reference for the clean and efficient use of energy. Editor/He Yuting
