A heat sink is used to absorb heat produced by a vehicle. The heat sink uses an endothermic catalytic alcohol dehydrogenation reaction to assist with the absorption of excess heat produced in the electronics of the vehicle. In some embodiments, the alcohol can be pre-heated by absorbing heat from various components of the vehicle. Excess heat from the various components or from the vehicle engine can be used to vaporize the reaction fluids in order to further absorb additional heat. Reaction fluids can also be sent to the vehicle's engine/burner for use as a supplemental fuel.

The apparatus of claim 1, wherein the reaction zone is not in fluid communication with the second vessel. 3. The apparatus of claim 1, wherein the catalyst is operable to dehydrogenate at least a portion of the alcohol at a temperature supplied to the reaction zone within the range from 0° C. to 150° C. 4. The apparatus of claim 1, wherein the catalyst is operable to dehydrogenate at least a portion of the alcohol at a temperature supplied to the reaction zone within the range from 0° C. to 80° C. 5. The apparatus of claim 1, wherein the alcohol is selected from the group consisting of isopropanol, butanol, pentanol, and combinations thereof. 6. The apparatus of claim 1, further comprising a separation zone operable to remove the unreacted alcohol from hydrogen and dehydrogenated hydrocarbon product. 7. The apparatus of claim 1, wherein the catalyst comprises an active metal component and a support component, wherein the active metal component is selected from the group consisting of rhodium, ruthenium, and combinations thereof, wherein the support component is selected from the group consisting of alumina, activated carbon, and combinations thereof. 8. The apparatus of claim 1, wherein the catalyst comprises an active metal component and a support component, wherein the active metal component is rhodium and the support component is alumina. 9. The apparatus of claim 8, wherein the weight ratio of the active metal component to the total weight of the catalyst is from 1:1000 to 1:20. 10. An apparatus for use as a catalytic alcohol dehydrogenation heat sink for a mobile vehicle, the apparatus comprising: a first vessel operable to have a volume of isopropanol contained therein;a second vessel operable to have a volume of jet fuel contained therein;onboard electronics for generating heat; anda heat exchanger disposed within the mobile vehicle, the heat exchanger comprising: a hot side in thermal communication with the heat from the onboard electronics;a cold side in fluid communication with the first vessel, the cold side adaptable for receiving at least a portion of the volume of the isopropanol from the first vessel; anda volume of catalyst, the catalyst operable to promote isopropanol dehydrogenation. 11. The apparatus of claim 10, further comprising a third vessel having a thermal fluid in thermal communication with the onboard electronics and the heat exchanger, wherein the thermal fluid is operable to transfer the heat from the onboard electronics to the heat exchanger to provide the heat required to initiate a dehydrogenation reaction with isopropanol in the presence of the catalyst. 12. The apparatus of claim 11, wherein the thermal fluid is selected from the group consisting of the jet fuel, oil, water, polyalpha olefin, air, and combinations thereof.
