Liquid hydrogen storage tank

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.
