【摘要】 在应对全球气候变化的背景下,氢能以其清洁、高效、无碳的特点而受到广泛关注。基于我国的资源禀赋、氢能需求及排放约束,煤制氢及碳捕集、利用与封存(CCUS)技术的集成应用对我国能源低碳转型具有重要意义。本文系统分析了我国煤制氢与CCUS技术集成应用的现状、机遇与面临的挑战,并为未来我国发展低碳煤制氢产业提供相关建议。结果表明:(1)相较其他制氢技术,现阶段煤制氢与CCUS技术的集成应用具备显著的成本优势;(2)CCUS技术可降低煤制氢过程约90%的二氧化碳排放,但相比可再生能源制氢其碳足迹仍是短板;(3)新疆、山西、陕西及内蒙古等地区可作为推广煤制氢与CCUS技术集成应用的优先区域;(4)煤制氢与CCUS技术集成应用面临的挑战主要包括缺乏公众认可度以及与可再生能源之间的竞争。未来我国应加强针对煤制氢与CCUS技术集成应用产业的顶层设计及相关技术的科普宣传,积极推进煤制氢与CCUS技术集成应用方面的研发和示范,为我国氢能产业的发展提供保障。更多还原

【Abstract】 Against the background of addressing global climate change, hydrogen has attracted much attention because of its characteristics of being clean, carbon-free and efficient.In view of China’s resource endowment, hydrogen demand and emission reduction demand, the integrated application of coal-to-hydrogen and carbon capture, utilization and storage(CCUS)technology is of great significance to China’s low-carbon energy transformation.The development status, opportunities and challenges of integrated application of coal-to-hydrogen and CCUS technology in China were analyzed systematically in this study to provide relevant suggestions for the development of coal-to-hydrogen with low-carbon emission in China.The results showed that:(1)Compared with other hydrogen production technologies, coal-to-hydrogen with CCUS has significant cost advantages;(2)Compared with hydrogen production from renewable energy, carbon footprint is the weakness of coal-to-hydrogen, even though CCUS technology can reduce carbon emissions by about 90%;(3)Xinjiang, Shanxi, Shaanxi and Inner Mongolia can be the first areas to deploy coal-to-hydrogen with CCUS technology;(4)The challenges of coal-to-hydrogen with CCUS mainly include lack of public recognition and the competition with renewable energy.In the future, China should strengthen the top-level design and publicity of coal-to-hydrogen with CCUS technology, actively promote the research, development and demonstration of coal-to-hydrogen with CCUS,so as to ensure the development of China’s hydrogen industry.更多还原
