Abstract
A system for storing ammonia comprises gas detector that is able to detect gases other than ammonia. The system further comprises thermally activatable ammonia stores, which can be activated to release ammonia upon heating. When the ammonia stores are not heated, the system is below ambient pressure and any leak will cause external gas to enter the system. Therefore, the gas detector is used to detect the presence of such external gas, which allows to detect leaks. The gas detector may be embodied as a thermal detector using a single heater and two temperature sensors for detecting a gas flow as well as external gas.
