The paper presents evaluation of the hydrogen liquefiers’ relevance and the necessity for a liquefaction process in solving the applied problems in various sectors of the Russian industry. It notes that, although high-performance liquefaction facilities are currently widely operating in Russia, the low-performance facilities are practically missing. It should be noted that various industries are urgently requiring them. Necessity and relevance of design, development and implementation of the low-performance hydrogen liquefier acceptable for introduction in a wide range of research tasks is confirmed. Patented design of the low-performance hydrogen liquefier by the LLC  SPE “InterPolaris” is described. It successfully passed testing at the small-scale production stage, where a closed cold cycle was introduced to produce liquid hydrogen provided the compressed hydrogen pre-cooling and its single throttling.
