Abstract
A fuel system for a power generator using hydrogen fuel and a method of recovering a safety marker added to the hydrogen fuel. The hydrogen fuel may be stored in a tank and delivered, in at least one of a gaseous phase and a supercritical phase, to a power generator. The hydrogen fuel is delivered with a fuel delivery assembly and contains at least one safety marker when the fuel is in the fuel delivery assembly. The at least one safety marker is separated from the hydrogen fuel, using, for example, a separator. The at least one safety marker separated from the hydrogen fuel is stored in a safety marker storage tank. The safety marker may be a visual safety marker, such as a noble gas, or an odorant.
