## Description

- description: 'Hydrogen has been significantly used as a clean energy carrier for
    decarbonization and global energy transition. Different hydrogen carriers have
    been widely utilized, including liquefied hydrogen, ammonia, methanol, liquid
    organic hydrogen carriers, and compressed gaseous hydrogen. Liquid hydrogen has
    a much higher volumetric energy density compared to gaseous hydrogen, where it
    occupies about 1/800th the volume of gaseous hydrogen at atmospheric pressure,
    making it efficient for storage and transportation. However, liquefied hydrogen
    has an extremely low liquefaction temperature of 20 K, representing an energy-intensive
    liquefaction process. Therefore, improving the efficiency of liquefaction significantly
    reduces its supply costs. The present study focuses on magnetic refrigeration,
    which enables an ideal refrigeration cycle without relying on Joule–Thomson expansion,
    to improve the efficiency of hydrogen liquefaction. Magnetic refrigeration is
    a cooling technology that utilizes the magnetocaloric effect (MCE) of magnetic
    materials. '
