Hydrogen gas system for combined refrigeration and power

A transport refrigeration unit (TRU) system for use with a refrigerated cargo system of a trailer, the TRU system comprising:

• a fuel cell configured to generate power for the TRU so that the TRU can refrigerate an interior compartment of the trailer;
• a cryo-compressed fuel tank to store a supply of cryo-compressed hydrogen;
• a heat exchanger;
• and
• a conduit system configured to transport the cryo-compressed hydrogen from the cryo-compressed fuel tank, through the heat exchanger for promoting refrigeration of the interior compartment, and to the fuel cell,
• wherein:
• the cryo-compressed hydrogen is transported through the heat exchanger for cooling refrigerant used to cool the interior compartment, and
• the conduit system is further configured to transport the cryo-compressed hydrogen from the cryo-compressed fuel tank and directly to the fuel cell.

A transport refrigeration unit (TRU) system for use with a refrigerated cargo system of a trailer, the TRU system comprising:

• a TRU;
• a fuel cell configured to generate power for the TRU so that the TRU can refrigerate an interior compartment of the trailer;
• a cryo-compressed fuel tank to store a supply of cryo-compressed hydrogen;
• a radiator and fan assembly disposed within the interior compartment;
• and
• a conduit system configured to transport the cryo-compressed hydrogen from the cryo-compressed fuel tank, through the radiator and fan assembly for refrigeration of the interior compartment, and to the fuel cell,
• wherein the radiator and fan assembly is disposed vertically above the cryo-compressed fuel tank to shorten a distance between the cryo-compressed fuel tank and the radiator and fan assembly and a length of the conduit.
