Dongfang Electric's 2000Nm³/h Alkaline Water Electrolysis Hydrogen Production Equipment Rolls Off the Production Line and Is Delivered in Zigong

en.Wedoany.com Reported - On November 6, the roll-off and delivery ceremony for Dongfang Electric's 2000Nm³/h alkaline water electrolysis hydrogen production equipment was held at the Zigong Hydrogen Energy Industrial Park in Sichuan Province. Zeng Jiming, Member of the Party Leadership Group and Deputy Director of the Sichuan Provincial Department of Economy and Information Technology, and Xiao Bingdong, Deputy Secretary of the Zigong Municipal Party Committee and Acting Mayor, attended the ceremony. Peng Lanlan, Deputy Mayor of Zigong; Wang Zhiwen, General Counsel and Chief Compliance Officer of Dongfang Electric Group; and Gong Liming, Secretary of the Party Committee and Chairman of Dongfang Hydrogen Energy, attended and delivered speeches. Yu Hong, Secretary of the Ziliujing District Party Committee; Li Liang, Member of the Party Committee and Deputy General Manager of Northwest Electric Power Design Institute; Wu Yimin, Member of the Party Committee and Deputy General Manager of Southwest Electric Power Design Institute; Liu Zijun, Deputy General Manager of Dongfang Boiler; and Jiang Hai, General Manager of the Chengdu Branch of China Quality Certification Centre, among others, attended the ceremony. More than 100 responsible persons from relevant units and expert representatives participated, and Xu Bo, Deputy Secretary of the Party Committee and General Manager of Dongfang Hydrogen Energy, presided over the ceremony.

The 2000Nm³/h alkaline water electrolysis hydrogen production equipment rolled off the line this time was independently developed by Dongfang Electric and is a flagship model built for large-scale green hydrogen bases. The equipment has three core advantages: low energy consumption, wide-load operation, and high safety assurance. The rated current density of a single stack reaches 4000A/m², and the DC power consumption is lower than 4.2kWh/Nm³H₂; it supports stable regulation over a wide load range of 25%-125%, with long-term operation energy consumption degradation of less than 1.5%/year and hydrogen in oxygen ≤1.5%. It can be widely used in scenarios such as centralized hydrogen production at large wind and solar bases, green hydrogen substitution in the chemical industry, and large-scale integrated hydrogen storage.

At the ceremony site, the Chengdu Branch of China Quality Certification Centre verified the actual operating performance of Dongfang Hydrogen Energy's 2000-standard-cubic-meter electrolyzer under loads of 25%, 50%, 75%, 100%, and 125%. Key indicators such as DC power consumption and hydrogen-in-oxygen content all met and exceeded the design values. This was the industry's first real-time test and demonstration of an electrolyzer's actual operating capability at a launch event, intuitively reflecting the equipment's performance stability and test verification capability.

In his speech, Gong Liming, Secretary of the Party Committee and Chairman of Dongfang Hydrogen Energy, stated that as the chain-leading enterprise of Sichuan Province's hydrogen energy industry chain, Dongfang Hydrogen Energy, relying on Dongfang Electric's long-term technological accumulation, has formed a complete product matrix comprising alkaline electrolyzers, PEM electrolyzers, fuel cell systems, and fully domestically produced membrane electrode assemblies. At present, a 500 MW alkaline electrolyzer production line has been built in Zigong, and a PEM electrolyzer production line has also been laid out, providing batch delivery capability for large-standard-cubic-meter hydrogen production equipment. In the next step, the company will continue to give play to its chain-leading role, deepen cooperation with research institutes and supply chain partners, and promote the high-quality development of the hydrogen energy industry with premium equipment.

The roll-off and delivery of this 2000Nm³/h large-standard-cubic-meter alkaline electrolyzer further enriches the product spectrum of domestically produced high-power hydrogen production equipment, provides a new equipment option for large-scale wind and solar hydrogen production and integrated hydrogen-ammonia-methanol projects, and also marks an important step by Dongfang Electric in the large-scale and engineering development of alkaline electrolyzers.
