研究了利用高温超导线圈的磁悬浮高效液氢存储系统。该系统在紧急情况下也具有高安全性，例如地震，具有地震隔离以吸收由设置在地面侧的HTS悬浮线圈提供的振动。在这种紧急情况下，认为在HTS线圈中产生大量的交流损耗，并且绕组温度可能升高以导致线圈失超。自激振荡式热管的热传导特性远大于固体热传导，本研究利用自激振荡式热管来冷却线圈绕组。结果，可以实现配备有OHP冷却系统的HTS线圈，支持通常操作中的低热负荷和紧急情况下的高热负荷。
Highly efficient liquid hydrogen storage system is studied with magnetic levitation using high-temperature superconducting (HTS) coils. The system also has high safety in case of emergency, such as an earthquake, with a seismic isolation to absorb vibrations provided by HTS levitation coils setup on the ground side. In such an emergency case, it is considered that a large amount of ac losses are generated in HTS coils, and the winding temperature may rise to lead to a coil quench. In this study, the self-oscillation-type heat pipe (OHP), whose thermal transport property is much greater than that of solid thermal conduction, is used to cool the coil windings. As a result, an HTS coil equipped with an OHP cooling system can be realized, supporting both low heat loads in the usual operation and high heat loads in an emergency.
