Description
At the National Institute for Materials Science (NIMS) in Japan, a project on high-efficiency hydrogen liquefaction by magnetic refrigeration is being carried out under the JST-Mirai Program. Liquid hydrogen is a key medium for storing and transporting hydrogen as an energy carrier, yet conventional gas-cycle liquefiers rely on compression work and reach only 20–30% of the Carnot limit. Magnetic refrigeration, which exploits the magnetocaloric effect, requires no compressor and thus offers substantially higher thermodynamic efficiency. In this presentation, we report the recent achievement of more than 60% of the Carnot limit in the active magnetic regenerator over a temperature range around the hydrogen liquefaction temperature, together with other progress in the project.
