We learned from the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences that the Institute's National Key Laboratory of Low Temperature Science and Technology recently proposed a direct electrolysis seawater hydrogen production strategy using alternating current instead of traditional DC electricity to generate hydrogen locally, thereby solving the problem of sedimentation bottlenecks in seawater electrolysis to produce hydrogen from the root. This technological achievement shows significant economic and flexibility advantages: no seawater pretreatment or ion exchange membrane is required, the cost and system complexity of hydrogen production are significantly reduced, and it can be coupled with offshore renewable energy power generation systems to achieve “offshore power generation - local hydrogen production” integration, and provide a low-cost and sustainable source of green hydrogen for the upstream hydrogen energy industry chain. At the same time, the new strategy for directly electrolysis of seawater with alternating current to produce hydrogen can co-produce high-value-added glycolic acid products while producing hydrogen, achieving “two benefits from one electricity”, further improving economic efficiency.
