基于文献计量学的制氢与CCUS技术耦合研究现状及趋势分析

氢能是未来能源的“终极形态”，目前工业上主要的制氢方式为化石燃料制氢。CO₂捕集、利用和封存(CCUS)技术是实现氢气从“灰氢”向“蓝氢”转变的重要手段，对国家“双碳目标”的实现至关重要。文章以Web of Science核心合集数据库为数据源，利用CiteSpace软件对制氢与CCUS技术耦合领域的文献来源、研究力量、研究热点和研究前沿进行分析。结果表明，中国的发文量居于世界首位，与其他国家有着广泛的合作基础，国内外研究所和高校为主要研究力量；吸附强化甲烷蒸汽重整(SESMR)制氢技术、化学链燃烧(CLC)制氢技术以及催化剂、吸附剂、载氧体为主要的研究热点；金属载氧体处在研究前沿，研发具有催化和吸附作用的复合催化剂与应用CLC技术和煤气化结合的电、氢联产工艺到火电行业是未来研究发展的两大方向；考虑到“双碳目标”的政策压力和碳税的额外支出，配套CCUS的制氢技术仍是一个优选的方案。

Current Research Status and Tendency of Hydrogen ProductionCoupled CCUS Technology Based on Bibliometrics

Hydrogen energy is the “ultimate form” of energy in the future. Currently, industrial production of hydrogen mainly relies on fossil fuels. Carbon capture, utilization and storage (CCUS) is an important way to realize the transformation from “grey hydrogen” to “blue hydrogen” and “dual carbon goals”. In this paper, related literatures were collected from the Web of Science core collection. CiteSpace software was used to analyze the literature source, research strength, research hotspots and research frontiers in the coupling field of hydrogen production and CCUS technology. The results show that China ranks the first in the number of publications and also has extensive cooperation with other countries. The main research forces at home and abroad are research institutes and universities. Sorption enhanced steam methane reforming (SESMR) hydrogen production technology, chemical looping combustion (CLC) hydrogen production technology, catalysts, adsorbents and oxygen carriers are the main research hotspots. Metal oxygen carriers are at the forefront of research. Development of composite catalysts with catalytic and adsorption functions and application of electricity-hydrogen generation technology combining CLC technology and coal gasification in the thermal power industry are the two main research directions in the future. Considering the industry-wide adoption of “dual carbon goals”and the additional cost of carbon tax, the hydrogen production technology accompanying CCUS is still a preferred option.
