Technology theme: Innovative Hydrogen liquefaction technologies desired in future society
To realize a future society advanced in energy saving and carbon lowering, the utilization of liquid hydrogen is essential. Liquid hydrogen has as a volume 1/800 that of hydrogen gas, and advantages related to mass transportation, mass supply, mass storage, space saving, and super-high purity. The present hydrogen liquefaction process with a compressor has disadvantages, including low liquefaction efficiency at manufacturing and loss resulting from evaporation. The development of high-efficiency, low-cost, compact, durable, and innovative technologies for hydrogen liquefaction is expected to enable the mass utilization of hydrogen and contribute to an increased volume of hydrogen use for hydrogen power generation, storage of surplus power, and means of transportation.

Summary：
Liquid hydrogen has a volume approximately 1/800 that of gaseous hydrogen, offering advantages such as large-scale transport, supply, and storage. However, its extremely low liquefaction temperature of 20 K (−253°C) requires substantial energy input. Achieving high liquefaction efficiency—beyond the limits of conventional gas-cycle refrigeration—is essential for cost reduction.
In this project, we aim to advance the development of high-performance magnetic materials and the construction of high-efficiency magnetic refrigeration systems toward the deployment of intrinsically high-efficiency magnetic refrigeration technology. By integrating these technologies, we develop a system capable of flexibly switching between hydrogen liquefaction and recondensation.
Furthermore, through the practical deployment of this technology, we will expand the utilization of liquid hydrogen and support the establishment of a hydrogen value chain.
