Cost optimized CO2 pipeline transportation grid: A case study from Italian industries
No full textThis paper presents the feasibility study of CO 2 sequestration from the sources to the sinks in the prospective of Italian Industries. CO 2 produced at these sources captured, compressed to supercritical pressures, transported via pipelines and stored in underground geologic formations such as depleted oil and natural gas reservoirs, un-minable coal seams and deep saline aquifers. In this work, we present the optimized pipeline infrastructure for the CO 2 with appropriate constraints to find lower cost system by the use of nonlinear optimization software LINGO 11.0. This study was conducted on CO 2 transportation complex network of Italian Industries, to find minimum cost network for transporting the CO 2 from sources to the sinks

Analysis And Statistic Evaluation Of Distributed Generation In Italy
No full textThis paper presents a complete analysis of the state of the art and the legislation of distributed generation in Italy, which is similar to other EU countries, and statistic data on combined heat and power plants installed in Italy. Data was collected from a large number of sources, because most of the small size plants are operated by IPP without an electrical exchange contract with the grid and are not documented. The results of this research has allowed to show that 22.000 MW can be generated by over 1600 power plants spread over the Italian territory. A more detailed analysis and validation of the information was done with reference to Umbria, a central Italian region. The whole database was examined with several correlations in order to facilitate the analysis of the national situation. It is thus possible to query the database in order to determine the types of users, the typical size for different users and their geographic distribution. This tool is extremely helpful in the design of new power plants and in the definition of the potential future market
European project Educa-RUE: An example of energy efficiency paths in educational buildings
No full textThe aim of Educa-RUE project is to improve energy performance in building sector at local level and with particular attention to educational buildings, by promoting the ability of local players to guide and orient initiatives, designed to encourage energy saving by means of specific measures and integrated tools.
The project is therefore focused to speed up the implementation of European Directive on Energy Performance in Buildings, EPBD (2002/91/EC), in Member States at local government level and to ensure its operability, within the various national legislations of reference.
Educa-RUE lasted 30 months, from January 2008 to June 2010, and involved the following eight partners: for Italy, Provinces of Potenza (project leader), Perugia, Rieti and Palermo; for other Countries,
Climate Energy Ltd. Essex and Energy Solutions North West London (UK), Associación Aragonesa de Entidades Locales ASAEL (Spain), Municipality of Prenzlau (Germany).
A number of closely interconnected actions were carried on in eight Work Packages (WPs) to face the energy efficiency aspects identified as primary problems by the partners. The project developed a model
process, known as ‘‘Educa-RUE method’’, to assess possible policies of intervention on educational buildings, owned or managed by each Partner.
In particular the Province of Perugia, leader of WP 2 and 5, provided guide lines and tools in order to: identify the state of the art of EPBD implementation and the main non-technological barriers, which are
preventing its application at local level; select, within the Province/area patrimony, the most suitable educational building, to be used as a shining example to develop the following testing phases of the project; carry on an energy check, or audit, of selected buildings, by involving the educational community as user and active participant in the whole process; elaborate an executive project, concerning the description of all the building elements (structure, roof, heating/cooling plants, etc.) which need to be replaced/ improved and the application of an energy/environmental assessment; plan refurbishing interventions for the rest of the school buildings directly managed by each Partner, according to specific priority selection criteria, which represents a guiding and coordinating act for those Administrations directly or indirectly interested in the Project.
This paper presents the results obtained by testing and proving Educa-RUE method in different regional areas. Its findings can be extended to other building typologies in order to create a reference model for local planners and responsible
Opportunities and criticisms of voluntary emission reduction projects developed by Public Administrations: Analysis of 143 case studies implemented in Italy
No full textThe United Nations Framework Convention on Climate Change (UNFCCC) sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change. Besides the “flexibility mechanisms” defined by the Kyoto Protocol to lower the overall costs of achieving their emissions targets, The Voluntary Green House Gases (GHG) reduction projects can have a lead role in GHG reduction in “non Emissions Trading System ETS sectors”. Nowadays, the voluntary market is characterised by critical aspects, such as fragmentation, lack of accounting, monitoring and validation rules that have led to the low spread of voluntary emission reduction projects developed by local authorities in the European Union despite their high potentiality.
The aim of this paper is to test the applicability of voluntary emission reduction projects in the public sector following a homogeneous and consistent pattern. A research has been performed at local level on 143 voluntary emission reduction projects implemented by Public Administrations in Northern and Central Italy in renewable energy, energy efficiency and transport sectors. The applicable standards and methodologies have been checked and the case studies have been analysed though a three-step process: Preliminary additionality assessment; Projects selection; Validation of the selected project. The assessment shows that energy efficiency projects, once overcoming additionality issues, are the most promising for public entities while renewable energy and transport projects resulted to be mainly affected by double counting problems and lack of reliable methodologie

Design of a multipurpose “zero energy consumption” building according to European Directive 2010/31/EU: Architectural and technical plants solutions
No full textConsidering the significant impact that the residential sector has on energy consumption, it is particularly important to implement policies aimed at improving energy efficiency in buildings. Highly energy efficient buildings can either save primary energy or disseminate the use of the most suitable technologies to be used in new constructions.
Due to those reasons, the Municipality of Città della Pieve promoted the creation of a “Renewable Energy Park” in a deprived area of its territory, where some green technologies could be installed and tested. This site has also been considered as an optimal location for an educational/demonstrative “zero energy consumption” building for multifunctional activities and realized with the most innovative techniques to save energy.
The building may be considered as an example to study and optimize the benefits of higher energy efficiency together with the use of renewable energy systems.
In this paper the technical solutions adopted both in the building envelope and the technical plants are described and discussed. A simulation of the behaviour of the building in summer and winter was carried out in order to assess the benefits that can be obtained both in energetic and economic terms
DESIGN OF A MULTIPURPOSE “ZERO ENERGY CONSUMPTION” BUILDING ACCORDING TO EUROPEAN DIRECTIVE 2010/31/EU: LIFE CYCLE ASSESSMENT
No full textThe Municipality of Città della Pieve in central Italy, promoted the creation of a “Renewable Energy Park” in a deprived area of its territory, to provide a space where the main technologies for the production of green energy could be installed. An educational/demonstration “zero energy consumption” building for multifunctional activities will also built with the most innovative techniques to save energy. This paper presents the results of the life cycle assessment (LCA) of the “zero energy consumption” building for a useful life of 50 years. All life cycle phases were included in the research: acquisition and production of materials, on-site construction and use/maintenance, demolition and material disposal. Moreover, a few different disposal scenarios were considered. The LCA modeling was performed using the SimaPro software application, connected to the Ecoinvent database. The environmental impact of the zero energy consumption building was assessed by using specific indicators
