Chinese scientists achieve breakthrough in direct seawater hydrogen production research
In China, Xinhua reported that a group of Chinese scientists have proposed a systematic assessment framework for the large-scale industrial application of direct seawater electrolysis for hydrogen production, providing theoretical support for the development of the marine green hydrogen industry.
According to a recent research article published in the journal Nature Reviews Clean Technology, the researchers from Sichuan University and Shenzhen University integrated the coupled effects of multiple factors in actual marine environments into the research system of seawater-based hydrogen production, extending the understanding from microscopic reaction mechanisms to macroscopic engineering scale-up.
The report highlighted that direct seawater electrolysis can use seawater and offshore renewable energy to produce hydrogen. However, the complexity of the composition and dynamics of seawater, such as composition fluctuations, wind-wave disturbances and salt spray corrosion, has hindered the transition from laboratory-scale breakthroughs to industrial scale.
This study systematically reviewed the key microscopic mechanisms of direct seawater electrolysis and critically analyzed the applicability and limitations of various approaches to engineering scale-up, according to the report.
