In this paper, we present a bibliographical review of tri-generation systems using renewable fuel. These systems are used to produce cold, heat and power from mainly one fuel source. This mode of operation increases overall efficiency and allows better use of the input fuel. Most tri-generation systems use a fuel cell for its reliability and performance. Furthermore, fuel cells produce heat and electricity at a very high efficiency compared to classical systems. A part of produced heat is recovered to produce cold by an absorption cycle when necessary. The fuel cell can be fed by various fuels, including natural gas, hydrogen produced from renewable or biomass gasification. The overall efficiency depends on the configuration and management of the entire system. The optimal sizing of tri-generation systems is a complicated task. It generally requires two optimization algorithms, one to optimize power flows within the system and the other to optimize the size of the elements. The optimal sizing of tri-generation systems requires two optimization algorithms, one to optimize power flows within the system and the other to optimize the size of each element of the system. Between 75 and 95%, efficiency can be attained depending on the choice of production system and energy management strategy. Keywords Tri-generation • Fuel cell • Hydrogen 23.1 Introduction Typically, a tri-generation system produces electricity, heat and cooling from a single source (Fig. 23.1). Products are adjusted to meet the energy demand of a group of residences according to demand. The major advantage of tri-generation is an efficient use of produced energy, lower pollutant emissions and security of supply [11]. Fuel cell technology is integrated into tri-generation systems as it allows better control of

Summary This paper proposes the design of a new solar power‐based multigeneration system for generating hydrogen, ammonia, methane, and other beneficial outputs. This combined plant consists of the solar plant, Rankine cycle, organic Rankine cycle, single‐effect absorption with ejector, carbon dioxide capture, hydrogen, ammonia, methane, drying, hot, and freshwater generation plants. The overall plant is investigated utilizing the Engineering Equation Solver software. The energy and exergy efficiencies of the integrated plant are computed as 0.6689 and 0.6227. In addition, the largest exergy destructions in the system are 6924 and 4037 kW, which occur at the Rankine cycle and solar power cycle, respectively. Moreover, the thermodynamic performance of the combined plant is investigated through parametric works and the impacts of plant working conditions on the plant efficiencies are evaluated.

Graphene nanosheets have attracted appreciable interest in heat transfer augmentation due to the unique deposition characteristics. The porous morphology of the graphene deposited on the heating surface via self‐assembly is reported to retard the transition boiling significantly. However, less attention has been paid to ameliorate the heat transfer coefficient (HTC) of graphene‐dispersed solutions. Herein, silver ions are introduced into graphene nanofluids to ameliorate its HTC. During boiling, graphene nanosheets and silver nanoparticles simultaneously deposit on the heating surface to form a well‐structured porous graphene/silver hybrid coating. The newly formed surface is characterized for surface morphology, wettability, and roughness. The new surface coating enhances the HTC by up to 109% and maintains the retarded critical heat flux of graphene‐only nanofluids. The application of the enhanced boiling heat transfer for the thermal management of concentrated photovoltaics is studied. It is demonstrated that enhanced boiling allows for cogeneration of electricity and heat from concentrated photovoltaics at approximately fourfold increased production rate while maintaining efficient, safe, and reliable operation.
