“…The solar receiver transfer the thermal energy to the storage device being designed so that it transfers energy to the fluid during the on sun phase of the orbit, and stores thermal energy for operation during the shade phase. The working fluid is then cooled in the condenser associated to the radiator which rejects the waste heat to the heat sink (the outer space) [10].…”

Abstract. The aim of the article concerns to the description of the main achieved research results regarding the viability of a megawatt class space power plant based on the Rankine cycle. The main objectives are to find the key issues to improve the Rankine cycle efficiency. With the proposed modifications, the ideal thermal efficiency achieved using the proposed strategies increases significantly with respect to conventional power plants. This benefit associated to the reduction of the required payload capacity, reduction of the condenser radiation surface and reduction of the power plant or installation weigh; represent the main advantages of the proposed technique.

An analysis and design trade study was conducted to compare different solar dynamic power systems(SDPS) for space missions application. Closed Brayton Cycle(CBC), alkali-metal Rankine Cycle(RC), free-piston Stirling Cycle(SC) and cogeneration cycles were evaluated and also compared with each other. Conceptual designs were developed for cogeneration cycles of CBC combining with Organic RC or new two-phase power cycle, the Organic RC or two-phase power system recovers the waste heat from CBC to improve the system performance. The analysis and comparison of system performance utilized low earth orbit(LEO) 10 kWe power levels, including deployed area, efficiency, weight and cost. Using the conceptual design study as a basis, solar dynamic system would be a competitive power system for future space station and other space missions.

“…The final stage (5) is devoted to reach ultra-high temperatures by means of a solar concentrator in which temperatures can attain over 1100 C or 1370 K. As observed in figure 1, all heat exchangers can be by-passed in order to use only those heaters that could supply thermal energy. The working fluid at high enthalpy is expanded into the turbine (6) in which thermal energy is converted into mechanical-electrical energy by means of an electric generator [5], [6].…”

In this article it is described the analysis of the viability of a megawatt class power plant based on the conventional Rankine cycle to be applied on offshore structures as complementary renewable source thermal energy. The high temperature heat source from a solar concentrator combined with fossil fuel, the low temperature heat sink from sea water bottom, the use of residual heat from thermal engines refrigeration and exhaust gas heat associated to the thermal storage facilities at high temperatures, are the main characteristics for an efficient concentrated solar dynamic power plant for offshore environments. The case studied revealed the viability of the plant as a complement to the conventional fossil fuel based thermal energy based plants.Concentrated solar power; Offshore estructure; Rankine cycle; Solar Power plant; Thermal efficiency.
