CRYOSTORAGE SYSTEM

A cryogenic storage system comprising a cryogenic container for storing hydrogen, with an inner tank (1) and an outer container (2), wherein at least one cryogenic pump (21) is arranged in the inner tank (1) of the cryogenic container, wherein the cryogenic pump (21) conveys liquid and/or gaseous hydrogen in one or multiple stages via a discharge line (27) to a consumer (5), at a higher pressure than the pressure in the inner tank (1), wherein the inner tank (1) can be refueled via a refueling interface (14), wherein the refueling takes place at least in sections via the discharge line (27), wherein the refueling occurs via a spring-loaded check valve (25) or a changeover valve (26) into the inner tank (1).
