On September 28, 2023, Huadian Group achieved a significant breakthrough in its project in Qinghai. With the successful production of first party hydrogen with a purity of up to 99% by the Huadian Delingha PEM electrolysis water hydrogen production demonstration project 999% green hydrogen marks the official launch of the national "unveiling and commanding" major project and the first green electricity hydrogen production project in Qinghai Province.

This project is one of the key projects of Huadian Group in Qinghai Province, and it is also a major breakthrough in China's first attempt to produce green hydrogen in high-altitude areas. The successful operation of the project will undoubtedly have a profound impact on promoting the development of the hydrogen energy industry, promoting the consumption of renewable energy, and helping to achieve the "dual carbon" goal.

The Huadian Delingha PEM Electrolytic Water Hydrogen Production Demonstration Project started construction on November 3, 2022, with a total investment of 1 500 million yuan, with three sets of 200Nm3/h PEM electrolytic water hydrogen production systems set up, with an annual hydrogen production capacity of 153 tons. The project adopts a photovoltaic power generation+hydrogen production mode through the integration of photovoltaic and hydrogen storage technology, utilizing the abundant solar energy resources in Qinghai Province to directly electrolyze water for hydrogen production. This innovative technological route not only reduces the cost of hydrogen production, but also effectively promotes the extension of the hydrogen energy industry chain and the enhancement of the value chain, achieving green electricity and green hydrogen consumption.

It is worth mentioning that this project not only achieved significant breakthroughs in hydrogen production technology, but also broke the industry monopoly of high capacity and large parameter PEM electrolytic water hydrogen production abroad. Through independent production and manufacturing, independent construction, and independent operation and maintenance, Huadian Group has successfully achieved the first operation of the fully domestically produced and largest single reactor proton exchange membrane hydrogen production unit in China. This breakthrough has solved the bottleneck problem of localization of key core materials and equipment such as proton exchange membranes and gas diffusion layers, and has significant technological and industrial demonstration significance.

The Huadian Delingha PEM Electrolytic Water Hydrogen Production Demonstration Project is committed to the application of hydrogen energy "production, storage, transmission, and use", and will take a solid step towards the full chain development of Huadian Group's Qinghai region in the hydrogen energy field. It is conducive to promoting the further development of the hydrogen energy industry, enhancing the absorption capacity of renewable energy, and making greater contributions to achieving green and low-carbon development.  Editor/Yang Yang
