A compact hydride absorption refrigeration system with few moving parts for 10°Kelvin operation is disclosed and comprises liquid hydrogen producing means in combination with means for solidifying and subliming the liquid hydrogen produced. The liquid hydrogen is sublimed at about 10°Kelvin. By using a symmetrical all hydrogen redundant loop system, a 10°Kelvin refrigeration system can be operated for many years with only a fraction of the power required for prior art systems.

A refrigeration system for operation at temperatures lower than 20 degrees Kelvin, the system comprising: liquefying means for producing a volume of liquid hydrogen from gaseous hydrogen; a liquid hydrogen container for containing the volume of liquid hydrogen produced by the liquefying means; an absorption vessel containing a chemical sorbent which absorbs gaseous hydrogen, the absorption vessel communicating with the liquid hydrogen container; and cooling means for cooling the sorbent, wherein when the cooling means is activated, the sorbent absorbs gaseous hydrogen from the liquid hydrogen container to thereby freeze the hydrogen contained therein and thereafter sublime the frozen hydrogen.
