Title: Thermal fluid selection for long-distance heat transmission

A model for evaluation of fluids for long distance thermal energy transport is presented. The model uses power function approximations for physical and economical relations, and its simplified version provides analytical insights into the optimal allocation of major cost components as well as a solution for the total transmission cost. The model has been used to develop a criterion for screening candidate liquids for long distance thermal energy transport. The criterion derived is dependent on the physical properties and unit costs of the candidate fluids and on the transport requirements. It can be used for fast screening and ranking of a great number of fluids. This approach may save considerable effort by eliminating the need for detailed engineering, economic, environmental, and safety studies on those fluids which would ultimately prove economically undesirable. Representative fluids are discussed and compared with the reference case of transmission by hot water.
