Economical Incentives and Systems of Certification for the Production of Electrical Energy from Renewable Energy Resources
2007
In order to succeed in observing the international agreements undertaken in the Kyoto agreement protocol, today it is necessary to increase the electrical energy production from renewables energy resources (RERs). In this paper a complete description of the Italian incentive systems for the production of electrical energy from photovoltaic (PV) and other RERs is done. Moreover, some considerations about the effects of the incentive actions on the wide spread of RERs to produce electrical energy are reported; particular attention is paid in the economical analysis related to PY and wind systems.
Impact of non-programmable renewable sources in Day-Ahead Market in Sicily. Reasons to make more flexible and smarter the national transmission grid.
2014
This article describes technical and market aspects that characterize the Sicilian electrical system, the non-programmable renewable sources impacts on the energy markets (Day-Ahead Market and ancillary services market) and on Sicilian system operation, to evaluate the grid integration of renewable energy sources in a future Sicilian smart grid.
Life Cycle Assessment of repurposed electric vehicle batteries: an adapted method based on modelling energy flows
2018
Abstract After their first use in electric vehicles (EVs), the residual capacity of traction batteries can make them valuable in other applications. Although reusing EV batteries remains an undeveloped market, second-use applications of EV batteries are in line with circular economy principles and the waste management hierarchy. Although substantial environmental benefits are expected from reusing traction batteries, further efforts are needed in data collection, modelling the life-cycle stages and calculating impact indicators to propose a harmonized and adapted life-cycle assessment (LCA) method. To properly assess the environmental benefits and drawbacks of using repurposed EV batteries …
Microbial Fuel Cell with Ni–Co Cathode Powered with Yeast Wastewater
2018
Wastewater originating from the yeast industry is characterized by high concentration of pollutants that need to be reduced before the sludge can be applied, for instance, for fertilization of croplands. As a result of the special requirements associated with the characteristics of this production, huge amounts of wastewater are generated. A microbial fuel cell (MFC) forms a device that can apply wastewater as a fuel. MFC is capable of performing two functions at the same time: wastewater treatment and electricity production. The function of MFC is the production of electricity during bacterial digestion (wastewater treatment). This paper analyzes the possibility of applying yeast wastewate…

Oxygen-containing polycyclic aromatic hydrocarbons (OPAHs) in urban soils of Bratislava, Slovakia: patterns, relation to PAHs and vertical distributi…
2011
Abstract We determined concentrations, sources, and vertical distribution of OPAHs and PAHs in soils of Bratislava. The ∑14 OPAHs concentrations in surface soil horizons ranged 88–2692 ng g−1 and those of ∑34 PAHs 842–244,870 ng g−1. The concentrations of the ∑9 carbonyl-OPAHs (r = 0.92, p = 0.0001) and the ∑5 hydroxyl-OPAHs (r = 0.73, p = 0.01) correlated significantly with ∑34 PAHs concentrations indicating the close association of OPAHs with parent-PAHs. OPAHs were quantitatively dominated by 9-fluorenone, 9,10-anthraquinone, 1-indanone and benzo[a]anthracene-7,12-dione. At several sites, individual carbonyl-OPAHs had higher concentrations than parent PAHs. The concentration ratios of se…
I modelli urbani della ricostruzione post-sismica degli anni ‘60 a confronto con la contrazione demografica dei territori interni della Sicilia. Caso…
2021
Il contributo prende in esame gli esiti prodotti a lunga distanza dai modelli urbanistici adottati in Italia nel secondo dopoguerra, caratterizzati da dinamiche espansive e dotazioni di servizi pubblici dimensionati in base agli standard. Gli effetti della contrazione demografia su tali modelli insediativi, che dispiegano oggi una serie di problematiche che conducono alla necessità di una riorganizzazione spaziale, vengono osservati su un campione particolarmente significativo al riguardo rappresentato dalle città ricostruite ex-novo nel secondo Novecento a seguito di movimenti tellurici. Il caso in esame riguarda il terremoto della Valle del Belice del 1968 e descrive come le nuove città, …
ENERGY FOR ROMANIA FROM RENEWABLE RESOURCES
2012
The European Union admits the fact that energy is essential, for the development of the European economy, but that it also constitutes a challenge, due to the impact on climate change. In Romania, as well as in all the countries of the European Union, which have chosen to promote renewable energy, governments have come up with support frameworks for investors in this field. In Romania’s case, the option for green schemes and compulsory quotas was selected, meaning that each energy producer, which produces renewable energy, receives a number of green certificates for each MW produced, depending on the technology it uses. The price of such a green certificate varies between 27 – 55 Euros. The…
