Abstract
Systems and methods disclosed herein relate to a cryogenic refrigeration system which may use a compression based cryocooler or liquid nitrogen pre-cool to cool a medium to ˜80K, and may in conjunction with a magnetic refrigeration system operating in the sub-80K temperature regime to provide cooling to a medium to temperatures below 80K. In some embodiments, the disclosed system may be useful for cooling on the order of about 3 kg/day to about 300 kg/day of hydrogen gas to liquid form, with higher efficiency than a standard vapor compression based system. This higher efficiency may make the system a more attractive candidate for use in cryogenic cooling applications.
