Abstract
A fuel storage system and a method for detecting a remaining amount of fuel are provided. The fuel storage system may include a storage vessel which accommodates fuel including a solid material and gaseous hydrogen, one or more sensors that measure a first temperature in the storage vessel and a first internal pressure of the storage vessel, a controller that predicts a first remaining amount of the fuel based on the first temperature and the first internal pressure and based on a relationship among different values of temperature, different values of equilibrium pressure, and different values of remaining amounts of the fuel as measured by the one or more sensors at different times, and a display that displays the predicted first remaining amount of the fuel.
