The White Stone of South-Eastern Sicily: Urban and Territorial Identity
2017
La Sicilia è un territorio fortemente "segnato" dall'impiego massiccio della ricca varietà di materiali lapidei che la natura ha messo a disposizione: materia prima dalle differenti qualità petrografiche, colore, caratteristiche tecniche e con una vasta possibilità di impiego, sia come elemento costruttivo sia come pietra ornamentale. La "pietra bianca" di Siracusa, il basalto dell'Etna, la "pietra forte" del ragusano, la pietra di Sabucina di Caltanissetta e Niscemi, le calcareniti e le rocce tufacee delle cave di Carini e Aspra, il calcare grigio di billiemi nel palermitano e il tufo calcareo di Agrigento, caratterizzano gran parte degli insediamenti antropici dell'isola, espressione di u…
Economic performance assessment of building integrated photovoltaic system with battery energy storage under grid constraints
2020
Abstract In this work, a typical South Norwegian house with BIPV system is considered for potential application of on-site battery energy storage. Economic and technical operation performance analysis has revealed that such a system can perform techno-economically much better compared to its counterpart. Techno-economic performance of BIPV system with appropriate energy storage has been evaluated for grid power supply limits with appropriate energy tariff for minimizing the annualized energy cost. It has been assumed that the capital costs associated with PV has been included in the building mortgage and expected that in the near future, the grid power supply limits would be introduced and …
Techno-economic evaluation of PV based institutional smart micro-grid under energy pricing dynamics
2020
Abstract The solar photovoltaic (PV) system with battery energy storage have a lot of potential to provide reliable and cost-effective electricity and to contribute in micro-grid operation. However, the operational performance of such type of micro-grid system depends on many factors (e.g. techno-economic sizing, energy management among the sources, market energy prices dynamics, energy dispatch strategies, etc.). In this paper, a typical Indian institutional energy system has considered for techno-economic performance evaluation for operating as a smart micro-grid under market energy pricing dynamics. The institutional energy system has integrated PV, battery storage and DG for operating a…
On the modelling of an Acid/Base Flow Battery: An innovative electrical energy storage device based on pH and salinity gradients
2020
Abstract Electrical energy storage can enhance the efficiency in the use of fluctuating renewable sources, e.g. solar and wind energy. The Acid/Base Flow Battery is an innovative and sustainable process to store electrical energy in the form of pH and salinity gradients via electrodialytic reversible techniques. Two electromembrane processes are involved: Bipolar Membrane Electrodialysis during the charge phase and its opposite, Bipolar Membrane Reverse Electrodialysis, during the discharge phase. For the first time, the present work aims at predicting the performance of this energy storage device via the development of a dynamic mathematical model based on a multi-scale approach with distr…
Development of a membrane-less microfluidic thermally regenerative ammonia battery
2021
Thermally regenerative ammonia battery is a promising approach to make use of waste heat and generate electrical energy. However, according to literature, the price of the energy obtained by this device is much higher than alternative renewable technologies (such as wind, solar, geothermal, etc.). To make the process more viable for applicative purposes, it would be necessary to reduce dramatically the cost of the membrane or to avoid it. Hence, the aim of the present work is to increase the economic figures of thermally regenerative ammonia battery avoiding the use of membranes. It was concluded that this result can be obtained by developing the process in a microfluidic flow cell with lam…
An integrated energy simulation and life cycle assessment to measure the operational and embodied energy of a Mediterranean net zero energy building
2022
Abstract Net Zero Energy Buildings can play a key role in reducing the energy use, greenhouse gas emissions and the use of natural resources associated to the built environment. It is widely recognized that in low energy building a shift in relevance may occur from the operational to the embodied impacts. However, building performance assessment focus mostly on the operational phase and on primary energy consumption. This study aims to assess the energy and environmental impacts of a residential net zero energy building expanding the analysis to the full life cycle and to a wide range of environmental impact categories. The methodological approach integrates a non-steady state building ener…
Battery capacity estimation for building-integrated photovoltaic system: Design study of a Southern Norway ZEB house
2017
Building-integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand as well as overcoming the intermittency of the load and PV production. In Southern Norway, a Smart Village Skarpnes is developed for zero energy buildings (ZEBs). In this Smart Village, five houses are built with BIPV system. Its important to estimate the appropriate battery sizing with consideration of local PV production and load profile taking into account the battery characteristics with minimization of the annual electricity bill. In this study, real operational results of house (C6) from the Skarpnes Smart Village is used for estimating the capacity of battery energy storage fo…
Battery Capacity Estimation for Building Integrated Photovoltaic System: Design Study for Different Geographical Location(s)
2017
Abstract Building Integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand, improving the power quality and control dispatching of the power. Adding a proper size of battery ES to the grid-connected PV system could reduce the overall investment cost as well as reducing the grid-dependency. A typical battery energy storage capacity is going to be determined by considering the real-time operational (PV production as well as load consumption) data. In this study, real-time operational data of a residential load (C6 house) with BIPV system located Southern Norway as well as institutional load (Teri university) with BIPV located in New Delhi, India are …
Performance Assessment of Building Integrated Photovoltaic and Battery Energy System: A Case Study of TERI-Retreat Facilty in India
2019
Building integrated photovoltaic (BIPV) with energy storage can play an important role not only in demand side management but also in a micro-grid system in coordination with other distributed generators. The operational analysis of BIPV system and energy storage with contribution to local load profile is needed for its grid connected operation, as well as for integrating it in the micro-grid system. In this work, a typical institution has been selected, where the PV system and energy storage are operated for supplying local load in coordination with the grid. The institutional load profile has been analyzed with essential and non-essential loads for understanding the operation and contribu…
