【Ten Years of Rapid Development in Chemical Engineering Equipment】Direct electrolysis of seawater without desalination to produce hydrogen for offshore wind power, 1993–2023

This experiment received strong support from the Chinese Academy of Engineering, Fujian Province, Fuzhou City, and Fuqing City. The Chinese Academy of Engineering specifically organized a team of academicians to visit the site in order to witness the sea trials. The expert group believes that the equipment for direct electrolysis of seawater to produce hydrogen without desalination is well-designed and operates stably; tests have confirmed the feasibility of this technology, which can serve as an important approach for producing hydrogen from marine renewable energy in the future. This offshore pilot test was carried out in the Xinghua Bay offshore wind farm in Fujian during the middle and late part of May. It utilized the world’s first floating offshore hydrogen production platform integrated with renewable energy sources, named \"Dongfu-1\", which was developed jointly by Dongfang Electric Corporation and the team led by Academician Xie Heping from the Chinese Academy of Engineering. This platform is also a prototype for hydrogen production through direct electrolysis of seawater without desalination; it incorporates systems for on-site hydrogen production, intelligent energy conversion management, safety monitoring and control, as well as functions for loading, unloading, and lifting. After withstanding conditions such as winds of force 8, waves up to 1 meter high, and heavy rain, it operated continuously and stably for over 240 hours, thereby proving the feasibility and practicality of the principle and technology for hydrogen production via direct electrolysis of seawater without desalination, as conceived by Chinese scientists, in real offshore environments.

The significance of the success of this sea trial lies in the following: 01. It demonstrated for the first time the viability and stability of a completely new principle-based technology proposed by Chinese scholars in a real-world environment； 02、For the first time, an integrated technical system for offshore wind renewable energy and direct hydrogen production from seawater was implemented ； 03、The feasibility of direct hydrogen production from offshore wind power without desalination, resistant to marine environmental interference, was verified for the first time ； 04、For the first time, it achieved the speed of transferring cutting-edge findings from Nature’s flagship journal to engineering trials in China ； 05. The team of academicians from the Chinese Academy of Engineering is one of the practical examples of China’s pursuit of \"high-level self-reliance and strength in science and technology.\" It has enabled the development of a path toward such self-reliance in Chinese science and technology, encompassing original principles, disruptive technologies, domestically produced equipment, as well as a distinctive industrial model for hydrogen production through electrolysis.

It is understood that the research achievements related to the technology for producing hydrogen through in-situ direct electrolysis of seawater without desalination were published in the official edition of Nature on November 30, 2022, by the team led by Academician Xie Heping; these achievements were recognized as one of the top ten scientific advances in China in 2022. On December 16, 2022, Dongfang Electric Group signed an agreement with the team led by Academician Xie Heping from Shenzhen University/Sichuan University to officially pursue joint innovation in this technology, with Dongfang Electric Group responsible for the commercialization and industrial application of the results. The success of this sea trial marks significant achievements and positive progress in East Power Group’s efforts to achieve self-reliance and strength through high-level science and technology. The group is committed to building an integrated and open innovation system, striving to create a hub for original technologies, and is determined to keep the reins of science and technology firmly in its own hands.
