Assessment of the renewable energy production in a historical building for a touristic intended use: a technical-economic feasibility study

2011

This column deals about a study based on technical and economical feasibility of a combination of technologies and systems for energy production concerning electric, heating and cooling to install on a building in the historic centre of a Sicilian city (Italy). After a functional review and an energetic evaluation, the building will have a hotel destination. A first evaluation, made on a model set with the geometrical, thermo-physical and climatic data both of the building and the place, allowed to make a dynamic simulation to define the energetic monthly needs. The evaluation has been done considering different solutions and technologies. With the collected data we supposed a first sizing …

FORMULAZIONE DI INCAPSULANTI POLIMERICI PER MODULI FOTOVOLTAICI BIFACCIALI HJT

2022

Il crescente interesse per la salvaguardia dell’ambiente, principalmente motivato dai disastri naturali che sono incorsi numerosi nell’ultimo ventennio, ha dato un’ulteriore spinta alla ricerca sulle fonti di energia “green” rinnovabile non derivanti da combustibili fossili, che permetta all’uomo di continuare a provvedere ai propri fabbisogni in maniera più “rispettosa”. Infatti, le fonti energetiche rinnovabili che il nostro pianeta ci mette a disposizione sono innumerevoli: dall’energia meccanica ed elettrica prodotta dal vento, alle biomasse, la cui combustione in appositi impianti permette generazione termica e cogenerazione di calore ed elettricità; l’energia prodotta dalle maree e da…

Polar Wax as Adhesion Promoter in Polymeric Blend Films for Durable Photovoltaic Encapsulants

2022

Technological developments in the solar photovoltaic field must guarantee the high performance and low deterioration of solar cells in order for solar power plants to be more efficient and competitive. The solar cell needs comprehensive protection offered by a polymeric encapsulant, which improves UV stability, reduces water and moisture absorption, reduces oxygen and vapor permeability and enhances mechanical resistance. Moreover, high transparency and adhesion yields improved the solar panel performance. The current work analyzes polymeric films based on poly(ethylene-co-vinyl acetate) (EVA) and polyolefin (PO) for photovoltaic encapsulant use (the high temperature resistance is improved …

A brine evaporative cooler/concentrator for autonomous thermal desalination units

2011

In recent years growing attention has been paid to the problem of brine disposal due to the raising awareness of significant environmental issues related to the use of desalination processes for fresh water production. This is particularly relevant when desalination units are located in remote sites, characterised by major complexity in the construction and management of intake and outfall structures. In the present work a novel device, named brine evaporative cooler/concentrator (BECC, patent pending), has been developed for coupling with small-scale thermal desalination plants in order to reduce the problem of brine disposal. Such device fulfils two different functions: i) cooling of the …

Water-organic systems in closed-loop reverse electrodialysis for lower regeneration requirements

2016

Salinity Gradient Power (SGP) is an emerging opportunity to produce sustainable energy. Among the different SGP technologies, Reverse ElectroDialysis (RED) looks very promising. In a RED system the salinity gradient between two different solutions is used to directly produce electricity. Closed-loop RED is an innovative process, combining a RED unit with a regeneration system. If low grade waste-heat is used for the regeneration stage, in which the initial concentrations of the solutions exiting the RED unit are restored, the closed-loop can be seen as a RED-heat-engine able to convert thermal energy into electricity. The aim of this work is to perform a preliminary analysis of a regenerati…

Advanced Formation Fluid Evaluation While Drilling with a New Heavy Gas Detector

2012

In this paper, a chromatograph which exploits the benefits of FID technology optimized for the high resolution detection of heavier hydrocarbon gas components is described. The components analyzed span from n-hexane to toluene. Flame Ionization Detector (FID) technology is not new to gas detection on the field, however it had never been applied to the detection of gases heavier than n-pentane. The instrumentation has been installed and run on a number of wells in different fields and countries, and it has operated as a complement of an advanced surface logging system for a period of two years. Unlike other technologies presently utilized for this scope, this system reduces dedicated equipme…
