Abstract
Official abstract text for this publication.
A hydrogen fuel including a safety marker and a method and apparatus for adding the safety marker to the hydrogen fuel. The hydrogen fuel may be stored in a tank in a liquid phase and then heated to at least one of a gaseous phase and a supercritical phase. The safety marker may be added to the hydrogen fuel when the hydrogen fuel is in the at least one of the gaseous phase and the supercritical phase after heating the hydrogen fuel. The hydrogen fuel may be delivered in the at least one of the gaseous phase and the supercritical phase to a power generator, such as a gas turbine engine. The safety marker may be a visual safety marker, such as a noble gas, or an odorant.
First claim
Opening claim text (preview).
What we claim is: 1. A fuel comprising hydrogen and a visual safety marker, the visual safety marker being a noble gas and having a mole fraction in the fuel between 1×10 −10 mol/mol and 1×10 −2 mol/mol. 2. The fuel of claim 1 , wherein the hydrogen is liquid, and the visual safety marker is helium. 3. The fuel of claim 1 , wherein, when the fuel is burning, the hydrogen produces a flame and the molecules of the noble gas are excited by the heat of the flame to produce visible light. 4. The fuel of claim 1 , wherein, when the fuel is burning, the hydrogen produces a flame and the visual safety marker is capable of coloring the flame of the fuel to be visible in sunlight. 5. The fuel of claim 1 , further comprising an odorant. 6. The fuel of claim 5 , wherein the odorant is one of mercaptan or a sulfide. 7. An aircraft comprising a gas turbine engine, wherein a gas combusted by the engine comprises the fuel of claim 1 .
