Cryogenic tank system

Abstract

A cryotank system comprising a first cryotank device and a second cryotank device. The first cryotank device includes a first cryotank to hold hydrogen, an extraction line operable to feed a consumer, a pressure sensor operable to measure pressure in the first cryotank, a heating line into which a partial flow of the extraction line can be branched off at a first junction, a first heat exchanger arranged in the first cryotank, wherein the heating line extends through the first heat exchanger and returns into the extraction line after the first heat exchanger at a second junction, at least one switching element operable to activate or deactivate the first heat exchanger in response to a measured pressure by the pressure sensor, and a first filling line operable to facilitate filling of the first cryotank with hydrogen. The second cryotank device includes a second cryotank to hold hydrogen, and a second filling line operable to facilitate filling of the second cryotank with hydrogen. A connecting line is operable to fluidically connect the first filling line to the second filling line.
