全国首台套热耦合海水直接电解制氢装置稳定运行超500小时

Core Viewpoint - The successful operation of China's first heat-coupled seawater direct electrolysis hydrogen production device marks a significant breakthrough in the field of hydrogen energy, utilizing seawater and waste heat from nearby industries to produce high-purity green hydrogen efficiently [2][3]. Group 1: Technology and Innovation - The heat-coupled seawater direct electrolysis hydrogen production system, developed in collaboration with multiple institutions, has achieved over 500 hours of stable operation [2]. - The device operates at a capacity of 110 kilowatts and can produce 22 standard cubic meters of high-purity hydrogen per hour, with a direct current electricity consumption of only 4.2 kilowatt-hours per standard cubic meter of hydrogen [3]. - The project addresses common challenges in seawater hydrogen production, such as electrode blockage from calcium and magnesium deposits and corrosion from high concentrations of chloride ions, by developing corrosion-resistant catalysts and dynamic control technologies [2]. Group 2: Environmental Impact and Applications - The system is capable of processing approximately 800 tons of seawater annually, resulting in a yearly production of 192,000 standard cubic meters of high-purity hydrogen, which can power 100 hydrogen buses for a distance of 3,840 kilometers, reducing carbon dioxide emissions by about 170 tons [3]. - This technology aligns with China's coastal industrial layout, providing a new paradigm for zero-carbon hydrogen supply by capturing waste heat, sourcing seawater locally, and producing green hydrogen on-site [3]. Group 3: Future Developments - The project team plans to accelerate the scaling, engineering, and intelligent application of the equipment to support the transformation of traditional industries like steel and petrochemicals towards new productive forces, contributing to carbon neutrality goals and enhancing energy security [3].
