Multi-Objective Optimization of Urban Microgrid Energy Supply According to Economic and Environmental Criteria
2019
This study is focused on the optimization of the annual cost and greenhouse impact related to the supply of natural gas and electricity of an urban microgrid through the installation of components as renewable energy sources, energy storage units and converters. As input parameters of the optimization model, the energy demand of a medium density urban district was estimated, while average costs and emissions of equipment were collected in market reports and literature. The outputs of the model are the optimal size and the schedule of each component. Moreover, optimization analysis was carried out for two different scenarios, comparing Italian and Vietnamese energy system cost and environmen…
Blending Collaborative Governance and Dynamic Performance Management to Foster Policy Coordination in Renewable Energy Supply Chains
2020
As the use of renewable energy is growing worldwide, the wind industry is being endorsed as a promising source for clean energy supply. In this context, the strategic management of the supply chain is fundamental to pursue a steady expansion of renewable energy. However, the fragmentation between energy policy design and implementation has been considered as a major cause threatening the effectiveness in managing the supply chain. This problem has been provoked mainly by an unsynchronized and uncoordinated decision-making process that involves public and private institutions. This chapter proposes the adoption of a dynamic performance management approach for enhancing a collaborative govern…
Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
ForBioEnergy - Forest Bioenergy in the Protected Mediterranean Areas
2019
The ForBioEnergy project, funded within the INTERREG MED Programme 2014-2020, involved a Lead Partner (Regional Department for the Rural and Territorial Development, Sicily Region), 8 project partners from 4 Mediterranean countries (Italy, Spain, Slovenia and Croatia) and 4 Associate Partners from Italy (Ente Parco delle Madonie, AIEL, Enviland, Petralia Sottana) and Croatia. It is an innovative project which bets on the chance to favor the sustainable development of the rural areas through the exploitation of the forest biomass for the production of bioenergy. However, most of the Mediterranean forests are within protected areas, where the current regulatory restrictions and the lack of ma…
Urban Energy Hubs Economic Optimization and Environmental Comparison in Italy and Vietnam
2018
This paper aims to perform the minimization of the yearly energy supply cost from the main electricity and natural gas grids related to an energy district, considering the installation of different equipments. The case study refers to energy consumption of a medium density urban district and involves the exploitation of different energy sources and devices (photovoltaic systems, electrical energy storage, heat pumps and cogenerators). The analysis of the district energy supply is accomplished through an energy hub model. After a cost analysis related to the considered energy systems, a MILP algorithm was used for the optimization of a cost function and the simulation of various scenarios. M…
Towards the implementation of circular economy in the water softening industry: A technical, economic and environmental analysis
2020
Abstract To reduce the environmental impact of the industrial sectors, circular strategies should be implemented to purify the effluents and recover raw materials. In this context, a novel integrated methodological approach is proposed to identify the most suitable strategy to improve the sustainability of the water softening industry via the treatment and recycling of the produced wastewater. Different concentration technologies and energy supply systems are compared to find economically feasible and environmentally friendly treatment systems. The investigated chains present the same pre-treatment step (nanofiltration and crystallization) and different concentration technologies: Multi-Eff…
New solutions for energy supply: sea wave and offshore photovoltaic in Sardinia (Italy)
2018
This work illustrates a study on the integration among sea wave farm and off shore photovoltaic in Italian island (Sardinia). In order to exploit both energy sources, the paper presents an innovative prototype, designed and developed by Palermo University. According the data about sea wave and solar energy potential, we evaluated the installation of wave-solar energy farms, based on the prototype presented in this paper.

2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
Energy efficiency improvement in hospital buildings, based on the example of a selected type of hospital facility in Poland
2019
Abstract Energy demand in hospitals is of highly diverse nature: heat energy, cool energy and electricity. A guarantee of energy supply is required to ensure continuity of medical procedures. Taking care of the lowest possible costs of hospital operations, special attention should be paid to energy efficiency of the installations used in the hospital buildings. The paper presents an analysis of energy demand for heating, cooling, ventilation and lighting in an example hospital in Poland. The selected object was considered a reference as it was built according to a repetitive construction plan, according to which several dozen other hospitals were built in Poland. On the basis of data from 2…
Sustainable Energy Supply Based on Sunflower Seed Husk for Oil mills
2019
The use of biomass, including sunflower husk, for in-situ energy generation has undergone a development in Ukraine last decades. Within this work, four combined heat and power technologies based on oil utilization, husk combustion, gasification, and methanization have been investigated. Their electricity and heat potential has been determined. Criteria for techno-economical assessment of CHP technologies have been suggested. Husk biogas and gasification technologies are not mature. CHP plants based on husk combustion are competitive. Steam turbine generators with a nominal electric capacity higher 1.5 MW may be profitable too.
