“…The use of an anaerobic digestion process in waste treatment systems presents a twofold advantage. First, a significant energy recovery can be achieved through the use of the produced biogas [69]. In addition, the residue can be stabilized through an aerobic treatment of the digested sludge, and can be finally used as an organic soil improver in agriculture or for environmental restoration [70].…”

Anaerobic Digestion (AD) is a well-established process that is becoming increasingly popular, especially as a technology for organic waste treatment; the process produces biogas, which can be upgraded to biomethane, which can be used in the transport sector or injected into the natural gas grid. Considering the sensitivity of Anaerobic Digestion to several process parameters, mathematical modeling and numerical simulations can be useful to improve both design and control of the process. Therefore, several different modeling approaches were presented in the literature, aiming at providing suitable tools for the design and simulation of these systems. The purpose of this study is to analyze the recent advancements in the biomethane production from different points of view. Special attention is paid to the integration of this technology with additional renewable energy sources, such as solar, geothermal and wind, aimed at achieving a fully renewable biomethane production. In this case, auxiliary heat may be provided by solar thermal or geothermal energy, while wind or photovoltaic plants can provide auxiliary electricity. Recent advancements in plants design, biomethane production and mathematical modeling are shown in the paper, and the main challenges that these fields must face with are discussed. Considering the increasing interest of industries, public policy makers and researchers in this field, the efficiency and profitability such hybrid renewable solutions for biomethane production are expected to significantly improve in the next future, provided that suitable subsidies and funding policies are implemented to support their development.

“…Many scholars have suggested and assessed that integration of processes and poly-generation systems are promising instruments for achieving the dual objective of increasing the productivity of natural resources and minimizing the impacts on the environment [5][6][7][8]. On the other hand, local district heating systems are a popular method for supplying the heat demand of large-scale absorption chillers in district cooling projects in countries with developed district heating networks, especially in the Nordic countries [9][10][11][12][13].…”

The solar tri-generation system can enhance the use of solar energy in residences. In this paper, an evaluation of the performance and operating parameters of an absorption sub-cooled compression hybrid cooling (ASCHC) configuration based on the pairing of photovoltaic thermal (PVT) collectors is presented. The work includes the multi-culmination fractionation and chiller originator to the Natural Rankine sequence system to evaluate the critical thermodynamic parameters such as irreversibility ratio, fuel depletion ratio, improvement potential, and total exergy loss of the system. The study was carried out using the first law and second law of thermodynamics applied to each component of each system. Solar absorption-subcooled compression hybrid cooling system (SASCCHC) is a novel cooling system that consistently meets the demand of cooling load with solar irradiance change. It is a very efficient and economical solar cooling system. The hybrid system’s performance is higher due to the improvement of the evaporator temperature of the absorption subsystem. However, SASCCHC is complicated in terms of working process and performance simultaneously due to the coupling of the absorption and compression subsystems. In the prior methodologies, there is a lack of electrical output performances of PVT collectors. It is found that previous studies do not consider the changeable storage tank temperature, exergy destruction rate estimation, and scrutinizing of thermodynamic parameters, which are significant potential. The present work incorporates the parabolic channel collector to estimate the exergy destruction rate, which increases the output working fluid temperature to a wide range significantly. Due to this, the proposed analysis’s outcome proficiently increases fuel depletion ratio and decreases exergy loss.
