## Description

- description: Japan’s Green Growth Strategy positions hydrogen as a key energy carrier,
    targeting large-scale demand growth and cost reduction. Among hydrogen carriers,
    liquid hydrogen offers high volumetric efficiency but requires energy-intensive
    cryogenic cooling. Magnetic refrigeration based on the magnetocaloric effect can
    significantly improve liquefaction efficiency. This talk presents AMR-based hydrogen
    liquefaction developed under the JST Mirai Project, covering the world’s first
    AMR liquefaction experiment (POC1) and a permanent-magnet-based re-condensation
    system with newly developed magnets (POC2).
