Current Status and Prospects of Direct Hydrogen Production from Seawater in China

This paper summarizes the current research status and future outlook of direct hydrogen production technology from seawater in China. With the growth of global energy demand and prominent environmental problems, hydrogen energy has been attracting attention as a kind of clean energy. The research on direct hydrogen production from seawater in China involves various fields such as electrolysis of water, photoelectrochemistry, electrocatalysis, membrane technology and polygeneration technology, and has made progress in demonstration projects, joint test bases, system integration and optimization, and industrial chain development. Technology application scenarios include offshore oil platforms, coastal islands, ocean development and protection, emergency energy supply and industrial parks. Looking ahead, China will focus on technology development priorities such as high-efficiency catalysts, advanced membrane technology, intelligent control systems, optimization of multi-generation technology, application of new energy integration technology, exploration of low-cost materials and improvement of seawater pretreatment technology. At the same time, it will promote the large-scale application and industrialization of seawater direct hydrogen production technology by constructing large-scale demonstration projects, perfecting industrial chain, expanding policy support and financing channels, strengthening international cooperation and technical exchanges, building human resources, as well as market promotion and application scenario expansion.
