First Large-Scale Commercial Water Electrolysis Hydrogen Production Project in Southwest China Begins Operation

China Huaneng Group Co., Ltd’s Pengzhou Hydrogen Production Demonstration Station recently sold its first batch of hydrogen, marking the beginning of the first large-scale commercial water electrolysis hydrogen production project in the Southwest region.

Located in Chengdu, Sichuan province, the Pengzhou Hydrogen Production Demonstration Station is the first large-scale water electrolysis hydrogen production project of China Huaneng Group. The hydrogen produced has a purity of 99.999 percent, and the station has a designed annual production capacity of 1,860 tons. Compared to hydrogen production from natural gas, the project reduces annual carbon dioxide emissions by 16,700 tons and can meet the hydrogen needs of 500 hydrogen fuel cell vehicles.

The project is equipped with two alkaline electrolyzers, each with a capacity of 1,300 standard cubic meters per hour, reaching up to 1,500 standard cubic meters per hour. The power conversion system of the project has a rectifier efficiency of 99 percent, achieving industry-leading efficiency and reliability.

China Huaneng Group is actively developing the green hydrogen industry, leveraging Sichuan province’s abundant renewable energy resources to develop new quality productive forces suited to local conditions. The company is focusing on advancing and demonstrating key technology and equipment for water electrolysis hydrogen production.

This first large-scale commercial water electrolysis hydrogen production project in Southwest China fills the gap in commercial green hydrogen production in Sichuan province, promotes the complementary development of water, wind, solar, hydrogen, and natural gas energy sources, and plays a significant role in driving the development and application of the green hydrogen industry chain.
