November 6 – Dongfang Electric held a ceremony at Zigong Hydrogen Industrial Park to mark the completion and delivery of its 2,000 Nm³/h alkaline water electrolysis hydrogen-production unit.

At the event, the Chengdu Branch of the China Quality Certification Center (CQC) conducted on-site performance verification of DEC Hydrogen Energy’s 2,000 Nm³/h electrolyser in front of attending officials and guests. Tests covered five operating load levels: 25%, 50%, 75%, 100% and 125%.

Key performance indicators, including DC power consumption and hydrogen content in oxygen, met or exceeded design specifications. According to the company, this was the first time in the industry that an electrolyser’s actual operating performance had been tested and demonstrated in real time at a product launch event.

The single-stack electrolyser features a rated current density of 4,000 A/m² and DC power consumption of less than 4.2 kWh/Nm³ of hydrogen. It supports stable operation across a wide load range of 25% to 125%, with hydrogen content in oxygen of no more than 1.5%. The equipment also features a low performance degradation rate.

Designed for large-scale hydrogen production, the system is suitable for applications including centralized hydrogen production at large wind and solar power bases, replacing fossil-based hydrogen with green hydrogen in the chemical industry, and large-scale integrated hydrogen storage.

Yang Jian, Chairman of Jiangsu Changqing Hydrogen Technology, and Gong Ningfeng, Chairman of Hydrosys (Beijing) Technology Co., Ltd., also delivered remarks congratulating Dongfang Electric on the delivery of the equipment.

Drawing on the 10,000-tonne-scale high-purity hydrogen supply station project in Changshou, Chongqing, Yang praised DEC Hydrogen Energy’s engineering capabilities in system integration, operating-condition adaptability and safety interlock systems. He expressed support for deeper industrial-chain collaboration to accelerate the large-scale deployment of domestically developed, high-capacity hydrogen-production equipment.

Gong Ningfeng shared operational experience from the integrated hydrogen production and refuelling station project in Changzhi, Shanxi. He highlighted the electrolyser’s low energy consumption, wide operating load range and high safety standards, as well as the results of joint technical development. He also expressed interest in continuing to develop demonstration projects, upgrade products and contribute to industry standards.

At the ceremony, Xie Guangyou, Deputy General Manager of DEC Hydrogen Energy, introduced the 2,000 Nm³/h alkaline water electrolysis unit, which was independently developed by Dongfang Electric. Designed for large-scale green hydrogen applications, the equipment offers three key advantages: high energy efficiency, flexible operation across a wide load range and enhanced operational safety.

The equipment received positive feedback from attending officials, industry experts and customers. Participants said it could improve hydrogen production efficiency, broaden the range of potential applications and reduce lifecycle costs, providing technical and equipment support for the further development of China's national hydrogen demonstration programme.

Dongfang Electric continues to focus on developing core hydrogen technologies independently and advancing product innovation. Its hydrogen portfolio includes alkaline electrolysers ranging from 300 to 2,000 Nm³/h, PEM electrolysers ranging from 10 to 500 Nm³/h, fuel cell systems ranging from 30 to 300 kW, and domestically developed high-performance membrane electrode assemblies (MEAs).

The company has completed construction of a 500 MW alkaline electrolyser production line in Zigong and is also developing a PEM electrolyser production line. These facilities support the company's capacity to deliver large-scale hydrogen production equipment in volume.
