人为二氧化碳排放过多导致的不良气候变化令人严重关切。氢作为清洁能源载体在缓解这些问题方面具有广阔的前景。然而，安全且实用地储存足够量的氢带来了巨大的技术挑战，这些挑战与强烈依赖于结构、化学和反应路径的材料特性相关。机械研磨和化学添加可有效改变各种氢化物体系。在改善氢吸附的热力学和动力学性质方面已经取得了相当大的进展。应对技术挑战的最后一步可能取决于混合系统，该系统可以在计算模拟的指导下利用改良的物理和化学吸附。
Undesirable climate changes due to excessive anthropogenic CO2emissions are of critical concern. Hydrogen as a clean energy carrier holds great promise in mitigating the problems. However, storing sufficient amount of hydrogen safely and practically poses large technical challenges, associated with materials properties that depend strongly on structure, chemistry and reaction path. Mechanical milling and chemical additions are effective in modifying various hydride systems. Considerable progresses have been achieved in improving thermodynamic and kinetic properties for hydrogen sorption. A final step to meet the technical challenges may rest with hybrid systems that can make use of modified physi- and chemi-sorptions, guided by computational simulations.
