内容概要：核能制氢就是利用核反应堆产生的热作为制氢的能源，通过选择合适的工艺，实现高效、大 规模的制氢；同时减少甚至消除温室气体的排放。现阶段，利用核能发电与电解水耦合制氢是一种具有 规模化应用潜力的核能制氢技术，而以水为原料与利用核反应热的甲烷蒸汽重整、高温蒸汽电解和热化 学循环则是代表未来发展方向的核能制氢技术。放眼全球，随着新一代核堆型的成熟与氢能产业的发 展，美日英中等核电大国均已启动本国的核能制氢工程。美国市场，早在2004年，美国能源部 （DOE）就启动了核能制氢研究工作。通过与电力企业合作，对在九英里峰核电厂在内的4个核电厂生 产清洁氢的示范项目提供支持。其中，九英里角核电站中的一座1250千瓦低温电解制氢设施（质子交换 膜电解槽）已于2023年3月启动运行，每天可生产560千克氢气。日本市场，日本原子力研究机构自1998 年建成运行热功率30MWe的高温气冷试验堆，成功实现在850℃下稳定运行。2004年冷却剂出口温度达 到950℃并成功完成了连续一周制氢试验运行。2019年，该堆连续运行150个小时，示范了热化学碘硫循 环制氢工艺。中国市场，中国核能制氢项目起步于"十一五"，研究了当初的主流 ...
