1. A heat management system for a thermal engine, comprising:
a source of hydrogen;
a first hydrogen conduit flowing a first flow of hydrogen therethrough, the first hydrogen conduit fluidly coupling the source of hydrogen to a fuel system of the thermal engine;
a second hydrogen conduit flowing a second flow of hydrogen therethrough, the second hydrogen conduit in thermal communication with an engine exhaust conduit to transfer heat from the engine exhaust conduit to the second hydrogen conduit, the second hydrogen conduit further in thermal communication with the first hydrogen conduit to transfer heat from the second hydrogen conduit to the first hydrogen conduit; and
an additional fluid conduit flowing an additional engine fluid therethrough, the second hydrogen conduit in thermal communication with the additional fluid conduit to transfer heat thereto, the additional fluid conduit in thermal communication with the first hydrogen conduit to transfer heat thereto.
