Electrolysis of water for hydrogen production is the hydrogen can be an important source, however, freshwater resources scarce, the water complex components need to purify after the electrolytic hydrogen production, and now the Chinese research team cracked the seawater directly electrolytic hydrogen production problems, is expected to form the Chinese original of“ocean green hydrogen”global emerging strategic industries.

According to the Shenzhen University, Public News, 11 November 30, Xie Peace Fellow with his guidance of Shenzhen University / Sichuan University PhD team to Shenzhen University is the first unit 30, in the Nature published a report entitled“A membrane-based seawater electrolyser for hydrogen generation”of research results. This study for the first time from a physical and mechanical and electrochemical combination of new ideas, to establish a phase transition shift driven seawater without fade in situ direct electrolytic hydrogen production new principles and technology, to branch out, completely isolated from seawater ions at the same time achieve a desalination process, no side effects, no additional energy efficient seawater in situ direct electrolytic hydrogen production technology breakthrough that the seawater when the pure water used in the water directly in situ electrolytic hydrogen production, the hack of the sea water directly to the electrolytic hydrogen production problems.

Phase transition shift driven seawater without fade in situ direct electrolytic hydrogen production principles

Green zero-carbon hydrogen energy is the future energy development of the important direction. As the hydrogen can be explosive growth, is projected to 2060, the country of hydrogen in demand will reach 1.3 billion tons, which annually consumes about 11.7 million tons in the electrolysis of pure water. However, freshwater scarcity of resources will be severely restricted the“green hydrogen”the development of technology. The ocean is Earth's largest hydrogen mine, to the sea to the water is the future of hydrogen energy development direction. But the complex waters of ingredients, about 92 chemical elements cause seawater to hydrogen production faces many challenges and challenges. The first desalination after the hydrogen is currently the most Mature of the seawater hydrogen production technology path, is currently in a global multinational to carry out large-scale demonstration projects. But the kind of technology is heavily dependent on large-scale desalination equipment, the process is complex and takes up a lot of land resources, further pushing up the cost of hydrogen and the construction difficulty. Early 70s of last century have scientists proposed that seawater possibility of a direct electrolytic hydrogen production from it? For half a century, the United States Stanford University, the French National Scientific Research Centre, University of Adelaide, Chinese Academy of Sciences and other domestic and Foreign well-known research team through catalyst engineering, Membrane Science and the like means a lot of exploration and research, is designed to crack the sea water directly to the electrolytic hydrogen production is facing the chlorine evolution side reaction, calcium and magnesium precipitation, catalyst deactivation and other problems. However, has been no breakthrough in the theory and principles thoroughly to avoid seawater complex components of the electrolytic hydrogen production affected, the scale of the efficient and stable seawater directly electrolytic hydrogen production principles and technology is still the world blank.

Thanks Peace Fellow of the presents from the physical mechanical and electrochemical combination of new ideas, hack seawater directly electrolytic hydrogen production is facing problems and challenges, thereby creatively pioneered the sea no fade in situ direct electrolytic hydrogen production of new principles and techniques. The results by molecular diffusion, interfacial phase balance and other physical and mechanical processes and the electrochemical reaction cleverly combined to create the phase transition shift driven seawater directly electrolytic hydrogen production a theoretical model that reveals Micron air gap path lower bound of the surface pressure difference between the seawater spontaneous phase change and mass transfer of the impact mechanism, the formation of an electrochemical reaction collaborative seawater migration of dynamic self-regulating stability of electrolytic hydrogen production method that cracked the harmful corrosive this troubled sea water electrolysis hydrogen production in the field of a half-century challenges, and currently has a patent pending.

At the same time, Xie peace fellow team developed the world's first 400L / h seawater in situ direct electrolytic hydrogen production technology and equipment, in the Shenzhen Bay seawater continuous run ultra 3200 hours, convincing from seawater to achieve a stable and large-scale hydrogen production process. In addition, the research team further developed the acidic and alkaline solid-state gel electrolyte, to indicate that the phase transition shift adaptation strategies of different electrolyte material, and is expected to be accompanied by PEM and AEM electrolysis technology iterative development. It is reported that the principles of the techniques may be out of promotion to the diversification of water resources such as river water, wastewater, Salt Lake, etc. directly in situ hydrogen production, as the resources enrichment enrichment and the production of energy to provide more efficient use of new ideas.

Sea no fade in situ direct electrolytic hydrogen production scale of the equipment and stability

“Sea no fade in situ direct electrolytic hydrogen production”integrate multidisciplinary theory, is our independent research and development of the originality of principle and technological breakthroughs, has opened up the global seawater hydrogen production of the new path; the technology can set“offshore wind power and other renewable energy use-seawater use of resources-hydrogen production”as a whole, is expected to form a non-fade, no additional catalyst engineering, no sea transport, pollution-free processing of the in situ seawater directly electrolytic hydrogen production new model, the true meaning will be inexhaustible of“waters of resources”into“waters of energy.” The technology of the future can be built with the offshore renewable energy combined with the integration of in situ seawater hydrogen production plant, is expected to become far-reaching the sea of renewable power large-scale development of breaking the key, accelerate the formation of multi-energy complementary China original“marine green hydrogen”global emerging strategic industries.

The Nature of the reviewers of the study given high rating:“this work provides an attractive strategy can be non-potable water for social and ecological sustainable fuel production, I think this is a major breakthrough!”

Nature expert reviewers comments on the results:“very few papers can be convincingly from seawater to achieve large-scale stable hydrogen production, but the thesis of the work is precisely to do this. They are the perfect solution to the harmful corrosive this long-troubled waters hydrogen-producing areas, it will open the low-cost fuel production doors, is expected to drive change towards a more sustainable world!”
