China successfully tested the technology of producing hydrogen at sea by directly electrolyzing seawater on June 2 at the Xinghua Bay offshore wind farm.

The test used Dongfu No. 1, a floating platform for offshore hydrogen production, and was verified by a team of experts from the Chinese Academy of Engineering (CAE). Dongfang Electric Power Corporation (DEC) jointly developed the platform with the team of Xie Heping, an academician at CAE. It integrates multiple systems, including on-site hydrogen production, intelligent energy conversion management, control, and safety assurance.

It is the world's first floating hydrogen platform that combines renewable energy, according to DEC, one of the world's largest manufacturers of power generation equipment. The platform has been operating stably for more than 240 hours after enduring high winds, 1-meter waves and storms.

The ocean is the largest source of hydrogen. However, the complex composition of seawater – more than 90 chemical elements, a large number of microorganisms and suspended particles – poses corrosion and toxicity problems, catalyst deactivation, reduced electrolysis efficiency and many other technical obstacles and challenges.

Indirect seawater electrolysis relies on large-scale desalination equipment, making the process complex, expensive, and land-intensive. For direct seawater electrolysis (without desalination), there has been no breakthrough in nearly half a century to prevent the complex components in seawater from affecting the hydrogen production system. Currently, water electrolysis technologies often rely on ultra-pure freshwater.

Xie said their method can separate the effects of more than 90 complex elements and microorganisms in seawater, changing conventional hydrogen production methods. According to Xie, the strategy of direct seawater electrolysis combined with offshore wind power could change the way the world develops energy in the future.

The related research was published in the journal Nature on November 30, 2022, and was also rated by the Chinese Ministry of Science and Technology as one of the top 10 scientific advances of 2022.
