确定并讨论了与四种替代储氢方法相关的重要传热问题，特别强调了车辆应用技术。对于压缩氢存储，压缩和中间冷却期间的高效传热减少了压缩功。此外，在加油过程中增强油箱内部的热传递可以最大限度地减少额外的压缩功。对于液氢储存，改进低温储罐的隔热性能可以显着减少液体蒸发造成的能量损失。对于使用金属氢化物的存储系统，由于颗粒床的有效导热率较低，因此增强传热至关重要。增强传热对于确保氢化和脱氢过程完成并防止氢化物床熔化也是必要的。对于以化学氢化物形式储存的氢，需要创新的车辆冷却设计才能使其被接受。
Significant heat transfer issues associated with four alternative hydrogen storage methods are identified and discussed, with particular emphasis on technologies for vehicle applications. For compressed hydrogen storage, efficient heat transfer during compression and intercooling decreases compression work. In addition, enhanced heat transfer inside the tank during the fueling process can minimize additional compression work. For liquid hydrogen storage, improved thermal insulation of cryogenic tanks can significantly reduce energy loss caused by liquid boil-off. For storage systems using metal hydrides, enhanced heat transfer is essential because of the low effective thermal conductivity of particle beds. Enhanced heat transfer is also necessary to ensure that both hydriding and dehydriding processes achieve completion and to prevent hydride bed meltdown. For hydrogen storage in the form of chemical hydrides, innovative vehicle cooling design will be needed to enable their acceptance.
