The U.S. Department of Energy (DOE) is sponsoring a comprehensive program to develop high-performance energy transmission fluids for use in district heating and cooling (DHC) systems. These fluids would substantially reduce flow frictional losses and enhance heat transfer. In system enhancement scoping studies, the fluids have been shown to yield potentially significant upfront capital equipment cost reductions by allowing the use of smaller pipes, pumps, heat exchangers, and storage tanks as well as reductions in operational costs.
