Summary In this study, thermodynamic analyses and environmental impact assessments of two integrated systems are comparatively performed for multigenerational applications. The first system consists of a heliostat solar heat and power generation field as energy source, a magnesium–chlorine (Mg–Cl) hybrid thermochemical cycle for hydrogen production, a steam Rankine cycle for power production, and a LiBr–water absorption chiller cycle for space cooling application. The second system is same as the first system except that the steam methane reforming (SMR) which considered for hydrogen production instead of Mg–Cl cycle. The SMR method is commonly used to produce hydrogen; however, it has disadvantages such as releasing CO2 emissions and utilizing fossil fuels for reforming. Mg–Cl cycle can be considered as a promising thermoelectrochemical cycle for water splitting because of its simplicity and applicability as well as possessing higher energy and exergy efficiencies and stability of chemical reactions throughout the cycle. Comparative energy and exergy performance assessments of both integrated systems are performed, and their assessment results are presented and discussed. In addition to the performance evaluation, environmental impact and sustainability assessments of both integrated systems are performed. Furthermore, the study compares two hydrogen production systems in terms of their performances and environmental impacts at varying conditions. Energy and exergy efficiencies of the present systems are found to be 28.4–18.4% for the system I and 43.2–27.4% for the system II, respectively. Exergetic sustainability of SMR‐based system is higher than that of Mg–Cl‐based system. However, Mg–Cl system does not emit greenhouse gases during production and is more environmentally benign in terms of greenhouse gas emissions. Copyright © 2015 John Wiley & Sons, Ltd.

Design and Optimization of an Innovative Solid Oxide Fuel Cell–Gas Turbine Hybrid Cycle for Small Scale Distributed Generation

Distributed power generation and cogeneration is an attractive way toward a more rational conversion of fuel and biofuel. The fuel cell‐gas turbine hybrid cycles are emerging as the most promising candidates to achieve distributed generation with comparable or higher efficiency than large‐scale power plants. The present contribution is devoted to the design and optimization of an innovative solid oxide fuel cell–gas turbine hybrid cycle for distributed generation at small power scale, typical of residential building applications. A 5 kW planar SOFC module, operating at atmospheric pressure, is integrated with a micro gas turbine unit, including two radial turbines and one radial compressor, based on an inverted Brayton cycle. A thermodynamic optimization approach, coupled with system energy integration, is applied to evaluate several design options. The optimization results indicate the existence of optimal designs achieving exergy efficiency higher than 65%. Sensitivity analyses on the more influential parameters are carried out. The heat exchanger network design is performed for an optimal configuration and a complete system layout is proposed. An example of hybrid system integration in a common residential building is discussed.
