[Achieve on-site hydrogen production for offshore power generation. Chinese team debuts new strategy for direct electrolysis of seawater hydrogen production through current generation] News on October 1. Reporters learned from the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (Institute of Physics and Chemistry) on October 1 that the National Key Laboratory of Low Temperature Science and Technology of the Institute recently proposed for the first time a strategy for direct electrolysis of seawater hydrogen production using alternating current instead of traditional DC power to achieve on-site hydrogen production through offshore power generation, solving the root cause of the sedimentation bottleneck problem of seawater electrolysis for hydrogen production. This technological achievement shows significant economic and flexibility advantages: it does not require seawater pretreatment and ion exchange membranes, significantly reducing hydrogen production costs and system complexity, and can be coupled with offshore renewable energy power generation systems to achieve the integration of "offshore power generation and on-site hydrogen production", providing a low-cost, sustainable source of green hydrogen for the upstream of the hydrogen energy industry chain.
