Publication number: 20230366511Abstract: A storage system for storing a cryogenic medium. The storage system includes a dual-wall cryogenic tank having an inner storage container for receiving the cryogenic medium and an outer container which surrounds the inner storage container. An evacuated hollow space is arranged between the inner storage container and outer container. A removal line serving as a removal duct forms a fluidic connection from the inner space of the inner storage container to a consumer connection. A first controllable line shut-off valve and a first heat exchanger are arranged in the removal duct. The storage system is operable such that, in the event of a crash, a shutdown of the storage system and escaping of the stored cryogenic medium is prevented. This is achieved via a first heat exchanger arranged within the evacuated hollow space, and a line shut-off valve which is arranged in the removal line.Type: ApplicationFiled: May 11, 2023Publication date: November 16, 2023Applicant: MAGNA Energy Storage Systems GesmbHInventors: Rainer PUCHLEITNER, Sergiy PUTSELYK
