Academician Xie Heping and his doctoral team from Shenzhen University/Sichuan University published their research results entitled “A membrane-based seawater electrolyser for hydrogen generation” in Nature. The research has established a new principle and technology of in-situ direct electrolysis for hydrogen generation without desalination driven by phase change migration from the combination of physical mechanics and electrochemistry for the first time, and has achieved a breakthrough in efficient in-situ direct electrolysis for hydrogen generation without desalination process, side reactions and additional energy consumption (i.e., using seawater as pure water and in-situ electrolysis for hydrogen generation directly in seawater). It is expected to form a global emerging strategic industry of “marine green hydrogen”, which is original to China.
Nature reviewers commented on the results: “Few papers have been able to convincingly achieve stable hydrogen production from seawater on a large scale, but the work in this paper has done exactly that. They have perfectly solved the long-standing problem of harmful corrosiveness in seawater hydrogen production, and will open the door to low-cost fuel production that promises to drive change toward a more sustainable world!”
