1. A storage system for storing an internal combustion engine exhaust gas liquid additive, and comprising:
a tank to store the additive, the tank including a lower half shell and an upper half shell that are manufactured as two separate parts and that are only assembled when at least one internal component has been inserted/positioned on at least one of the two separate parts,
wherein the at least one internal component is a heater fixed on the lower and/or upper shell, at least one of the lower or upper shells is made by injection molding a plastic, the lower and upper shells are assembled by welding their edges together, and a support of the heater bears several portions in relief so as to increase the volume of the additive that can be thawed.
