12月6日，我国首台（套）110千瓦级热耦合海水直接电解制氢系统装置通过了由中国科学院院士领衔的 专家组评审。该装置由崂山实验室联合中广核集团、山东师范大学与日照市岚山区政府共同研发，已实 现超过500小时的连续稳定运行。这标志着我国在海水直接电解制氢领域取得了从实验室迈向工程化应 用的关键突破。 记者了解到，该装置无须依赖北方沿海地区宝贵的淡水资源，而是将日照周边钢铁、石化等企业排放的 低品位余热注入海水，便能高效、稳定地转化为高纯度氢气。 "这不仅仅是产出一罐氢气，更是打通了一条'向大海要能源'的全新路径。"崂山实验室高级工程师秦建 光表示，该成果核心突破是解决了海水电解过程中钙镁沉积、氯离子腐蚀、寿命短等核心技术瓶颈，并 通过低品位废热高效利用降低设备成本与能耗，这为未来海水制氢和其他电解水制氢工艺提供了更高 效、低成本的解决方案。 长期以来，海水中的钙镁沉积易堵塞电极、高浓度氯离子腐蚀电解设备和催化材料，被业内视为海水制 氢的"致命伤"。该装置通过关键耐腐蚀催化剂开发与适配海水的动态调控技术，有效抑制氯离子对电解 设备及催化材料的腐蚀。此外，该装置同步利用电解系统低品位废热，耦合筛分系统联产高品质淡水 ...
