1. A fuel storage system comprising:
a fuel tank configured to store a liquid fuel;
a controllable pressure source for altering the pressure in an ullage space of the fuel tank;
a controller configured to:
determine a target pressure for the ullage space at a given time based on information relating to a temperature of fuel inside a different fuel tank at the given time;
calculate a value for the temperature of fuel inside the fuel tank at the given time based on the current value of the temperature inside the different fuel tank using a predefined relationship between temperature of fuel in the different fuel tank and temperature of fuel in the fuel tank; and
control the pressure source such as to cause the pressure in the ullage space to be substantially equal to the target pressure.
