A solar thermal energy transmission system having a bellows that sealingly interconnects a first structure to a second structure is disclosed. The bellows includes a surface that is compatible with a molten salt and is configured to resiliently deform in response to contraction and expansion of at least one of the first and second structures, to thereby accommodate relative movement of the structure(s) to which it is coupled.

1. A solar thermal energy transmission system comprising:a first structure; a second structure; and a bellows interposed between and sealingly interconnecting the first and second structures, the bellows having an interior surface and an exterior surface wherein at least one of the exterior and interior surfaces is compatible with a molten salt, the bellows being configured to resiliently deform in response to contraction and expansion of at least one of the first and second structures; wherein the first structure extends through an aperture in the second structure and the bellows inhibits fluid communication of the molten salt through the aperture. 2. The solar thermal energy transmission system of claim 1, wherein the first structure comprises a valve stem and the second structure comprises a bonnet.3. The solar thermal energy transmission system of claim 2, wherein the bellows is sealingly welded to a perimeter of the valve stem.4. The solar thermal energy transmission system of claim 1, further comprising an insulative shroud adapted to insulate the bellows.5. The solar thermal energy transmission system of claim 1, further comprising an auxiliary heater coupled to the second structure and being configured to heat said molten salt adjacent the bellows.
