Energy and Thermoeconomic Analysis of Energy Devices

Due to environmental and demographic impacts, there is a high probability of a series of changes occurring on our planet over the next decades. In addition, a significant increase in the prices of all hydrocarbons due to limited world reserves is expected in the next decades. The combined use of renewable energy technologies and alternative energy technologies is a promising approach to reduce global warming effects in the world. In this paper, a solar concentrated power plant analysis based on the Rankine Cycle (RC) is performed, heated by means of various renewable energy sources. First, solar energy is used, followed by wood biomass energy. The solar energy is used during days full of sunshine. The heat energy from the concentrated solar power system process, stored in the big heat reservoir, is used to produce hydrogen during the night and during cloudy weather. In the period without sunshine and when we use all heat from the heat reservoir, biomass energy is used. This article examines the efficiency of a specific thermochemical hydrogen production cycle called the Copper-Chlorine cycle (CuCl). In the article, energy and economy analysis for the case of central European market prices, will be analyzed.
