A system in one embodiment includes a detection unit (116), a boil- off auxiliary power unit (140), and a controller (190). The detection unit is configured to detect a characteristic of a boil-off gas stream (123) from a cryotank (110) configured to hold a cryogenic fluid. The boil-off auxiliary power unit (140) is configured to receive the boil-off gas stream (123) and use the boil-off gas stream to provide auxiliary power to a vehicle system. The controller (190) is configured to acquire information from the detection unit (116) corresponding to the characteristic; determine, using the information acquired from the detection unit, an available boil-off auxiliary energy that is available from the boil-off auxiliary power unit; determine a mode of operation of the vehicle system; determine a required auxiliary energy for the vehicle system; and to operate the auxiliary power unit based on the available boil-off auxiliary energy, the mode of operation, and the required auxiliary energy.
