Claim 11:
12. A liquid hydrogen reservoir, comprising:
a cryostatic container operable to hold liquid hydrogen;
a discharge line operable to discharge gaseous hydrogen in the cryostatic container;
a boil-off management system that includes:
a mixing chamber operable to mix the gaseous hydrogen with ambient air,
an exhaust gas line arranged downstream of the mixing chamber and operable to discharge the gas stream to the environment,

a return line operable to connect the exhaust gas line to the mixing chamber to facilitate a return flow of at least a partial stream of the exhaust gas line into the mixing chamber;
a boil-off valve, arranged in the discharge line for selectively opening and closing a flow connection of the discharge line to the boil-off management system;
a temperature sensor operable to detect a temperature value in the boil-off management system; and
a temperature-controlled valve arranged in the return line and operable to open and close the return line in response to the detected temperature value.
