Abstract: Various embodiments that pertain to fuel processing are described. A fuel processor can produce an endothermic reaction that cools a substance and produces a processed fuel from a raw fuel. A generator can employ the processed fuel to produce an electricity. The generator can supply the electricity to a load that uses the electricity to function. The load can become hot due to its functioning and can benefit from being cooled. The substance cooled by the fuel processor can cool load and in the process the substance can rise in temperature. This warmer substance can be transferred to the fuel processor to be cooled again and this cycle can continue. Further, the fuel processor can use the warmer substance to achieve the endothermic reaction.
