Special Issue Information
Dear Colleagues,
In the context of energy transition and decarbonization, the recovery of waste heat from industrial processes and energy system exhausts can significantly reduce the overall energy consumption and enhance the engines performance. This applies to both stationary or mobile applications (e.g., marine engines).
At the same time, the integration of different energy systems, considering both renewable and non-renewable sources, provides to improving the power and efficiency of the energy systems, also limiting the greenhouse gas and pollutant emissions.
Additionally, the integration and the hybridization enhance flexibility and versatility, overcoming constraints related to availability and programmability through poly-generation and the utilization of various energy sources.
Accordingly, a Special Issue focusing on the advantages of Waste Heat Recovery and Integrated Energy Systems acquire great importance in the overmentioned fields and may encompass research employing both numerical modelling and experimental approaches.
For instance, the Special Issue will delve into topics like Organic Rankine cycles, Kalina cycles, supercritical CO2 gas turbines, closed Brayton cycles, steam Rankine cycles, Stirling engines, and cascade power cycles, as concern the waste heat recovery.
Exploring the integration of various energy systems, the Special Issue will delve into Combined Cycle Gas Turbines (CCGT), Integrated Gasification Combined Cycle (IGCC), Combined Heat and Power systems (CHP), hybrid energy grids, hybridization of renewable sources with fossil and traditional fuels, solar-assisted gas turbines, externally fired gas turbines, and power-to-gas applications. The focus may also extend to the combined use of different fuels, incorporating the integration of the energy system with gasification and methanation systems and with other applications.

Title: A hybrid energy system based on externally fired micro gas turbine, waste heat recovery and gasification systems: energetic and exergetic performance analysis
Authors: Fabrizio Reale; Patrizio Massoli

Abstract: The opportunities related to the adoption of synthetic gaseous fuels derived by solid biomass are limited by the issues caused by the peculiarities of the syngas. Aim of this paper is to analyze several possible layouts of hybrid energy systems, in which the main thermal source is the organic fraction of municipal solid wastes. The case of a small community of about 1000 persons is analyzed in the paper. The examined layouts coupled an externally fired micro gas turbine with a waste heat recovery system based on both ORC and supercritical CO2 gas turbines. A thermodynamic analysis has been carried out through the use of the commercial software Thermoflex, considering the losses of each component and the not-ideal behavior of the fluids. Results of the numerical analysis highlighted that the introduction of a WHR system leads to an increase of at least 16% in the available net power, while a cascade hybrid energy grid can lead a power enhanced of about 29%, with a considerable increase also in the energetic and exergetic global efficiencies.
