Conceptual Study on Heat Transfer System for Space Solar Power System

It is estimated that the energy consumption all over the world will increase to nearly 3 times in 2050 and that the total amount of CO2 exhaust will increase 3 times also. Hence, it is expected the lack of energy resource and severe green house effect by CO2 may emerge in future. Space Solar Power System (SSPS) is one of the candidates with potential, among the various future power sources, because of almost eternal power supply with almost no emission of CO2. After a pioneering work by NASA in USA, some reference models are proposed and investigated by DLR in Germany, ISAS, and NEDO both in Japan, in which the power spectrum are underlying from 250MW to 1GW respectively. The conceptual design of System for Space Solar Power System has been developed actively in NASDA. Today, SSPS is supposed feasible, if economical rationality will be solved by promising technical scenario. In the report, the results from present survey of heat transfer system for SSPS reference model in NASDA is mentioned, in the view of technical criticality to realize the total system not only for the technical demonstration but also the commercial plant.
