engine cost is somewhat uncertain with the estimated cost being about 2.5 times the Rankine plant cost. The chemical energy transport has promise because of projected low cost, low losses and potential for storage of CO + gases. The potential of using a combination of distributed and central generation with a Brayton-Rankine topping cycle should be investigated. The waste heat from a Brayton engine on each dish can be carried to a centra! Rankine engine via water transport at 315°C. Storage was not addressed in this review of sun following plant operation, but will be considered in the next phase of this program.
