1. A device for operating an exothermic hydrogen consumer, wherein the device comprises the exothermic hydrogen consumer, at least one starter tank and at least one operating tank, wherein the at least one starter tank comprises a container which is pressure-tight to hydrogen filled with a first metal hydride which is incorporated into the operating tank, wherein the first metal hydride has an equilibrium pressure for the desorption of hydrogen of at least 100 kPa at a temperature of −40° C., and wherein the at least one operating tank comprises a container which is pressure-tight to hydrogen filled with a second metal hydride, wherein the second metal hydride has an absolute value for the reaction enthalpy for the hydrogen absorption reaction (|ΔHabs|) of less than 65 kJ/mol H2 and has an equilibrium pressure for the desorption of hydrogen of less than 100 kPa at a temperature of −40° C.
