1. A fuel storage system comprising:
a storage vessel configured to accommodate fuel, wherein the fuel comprises a solid material and gaseous hydrogen;
sensors configured to measure a first temperature in the storage vessel and a first internal pressure of the storage vessel;
a controller configured to predict 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 sensors at different times; and
a display configured to display the predicted first remaining amount of the fuel,
wherein, according to the relationship, a remaining amount of the fuel is inversely proportional to temperature and is proportional to equilibrium pressure.
