摘要
近年来,随着全球对低碳经济和能源转型的日益关注,氢能因其高能量密度和零排放特性,成为各国能源战略中的关键组成部分。与物理储氢技术相比,化学储氢因其能够在常温常压下提供更高的储氢容量和更稳定的储存过程,已成为氢能研究的重点方向。本文回顾了化学储氢材料的研究进展,主要集中于金属氢化物储氢和有机液体储氢两大技术,分别探讨了它们的储氢机制、性能优化及可持续发展路径。主要分为以下内容:金属氢化物储氢技术的研究进展,涉及不同金属氢化物储氢材料的性能优化、反应器优化设计及其经济性与环境影响评估;有机液体储氢技术的研究现状,讨论了有机液体储氢材料的选择、催化剂优化及其经济性与环境影响;其他化学储氢技术与方法,包括改性碳材料化学吸附储氢、化学储氢与固体氧化物燃料电池的结合,以及化学储氢与绿色制氢技术的结合。以上技术的深入比较与分析,旨在为未来化学储氢技术的优化与应用提供理论支持,并为氢能的可持续发展提供借鉴与参考。
In recent years,with the growing global attention to low-carbon economies and energy transitions,hydrogen energy has become a key component of national energy strategies due to its high energy density and zero-emission characteristics.Compared with physical hydrogen storage technologies,chemical hydrogen storage has become a major focus of hydrogen energy research because it can provide higher hydrogen density and more stable storage processes at ambient temperature and pressure.This paper reviews the research progress of chemical hydrogen storage materials,focusing on two main technologies:metal hydride hydrogen storage and organic liquid hydrogen storage.It explores their hydrogen storage mechanisms,performance optimization,and sustainable development pathways.The paper is divided into the following sections:Progress in metal hydride hydrogen storage technology,which includes the performance optimization of different metal hydride storage materials,reactor optimization design,and their economic and environmental impact assessments;The current status of organic liquid hydrogen storage technology,which discusses the selection of organic liquid hydrogen storage materials,catalyst optimization,and their economic and environmental impacts;Other chemical hydrogen storage technologies and methods,including modified carbon materials for chemical adsorption hydrogen storage,the integration of chemical hydrogen storage with solid oxide fuel cells,and the combination of chemical hydrogen storage with green hydrogen production technologies.Through an in-depth comparison and analysis of these technologies,this paper aims to provide theoretical support for the optimization and application of chemical hydrogen storage technologies in the future,and offer references for the sustainable development of hydrogen energy.
