Intense literature and research efforts have focussed on the exploration of complex hydrides for energy storage applications over the past decades. A focus was dedicated to the determination of their thermodynamic and hydrogen storage properties, due to their high gravimetric and volumetric hydrogen storage capacities, but their application has been limited because of harsh working conditions for reversible hydrogen release and uptake. The present review aims at appraising the recent advances on different complex hydride systems, coming from the proficient collaborative activities in the past years from the research groups led by the experts of the Task 40 ‘Energy Storage and Conversion Based on Hydrogen’ of the Hydrogen Technology Collaboration Programme of the International Energy Agency. An overview of materials design, synthesis, tailoring and modelling approaches, hydrogen release and uptake mechanisms and thermodynamic aspects are reviewed to define new trends and suggest new possible applications for these highly tuneable materials.

复杂氢化物中的氢储存：过去的活动和新趋势

在过去的几十年里，大量的文献和研究工作都集中在探索用于储能应用的复合氢化物上。由于其高重量和体积储氢能力，人们一直致力于确定它们的热力学和储氢特性，但由于可逆氢释放和吸收的恶劣工作条件，它们的应用受到限制。本综述旨在评估不同复杂氢化物系统的最新进展，这些进展来自过去几年由氢技术的 Task 40“基于氢的能量存储和转换”专家领导的研究小组的熟练合作活动国际能源署合作计划。材料设计、合成概述，
