NATURAL GAS SUPPLY CHAIN: A SYSTEM AND PERFORMANCE ORIENTED APPROACH

Global energy consumption has been increasing in recent years. Among the main global energy sources, natural gas stands out. It presents benefits from diverse points of view, low emissions for the environment, low price for the consumers, lower cost and simplicity in the supply. That is why, within the global policies of emission reduction, natural gas is considered the source of transition energy between fossil fuels and clean, renewable and sustainable sources of energy. Considering that natural gas is a non-renewable resource, it presents a significant and progressive reduction in reserves in some regions worldwide, but with ample possibilities for the discovery of new reserves and trans…

The role of LCA in reporting emission inventories for municipalities: experiences from the Convenant of Majors

I piani energetici ambientali regionali. Applicabilità degli indicatori proposti a scala nazionale (ISPRA) ed europea (EUROSTA).

2014

As it is well known, indicators represent effective tools in the aim of designing, monitoring and verifying energy and environmental Masterplans. At this regard, a large number of indicators do exist both at European and country Italian levels which designers can usefully apply to. Anyway, being such indicators released at a general European level, their actual verifiability should be properly checked when them are applied to the local level of a given territory. In the present work this issue is approached by referring to the Sicilian Energy and Environmental Masterplan (PEARS): on purpose, the themes proposed at European (Eurostat) and country Italian (ISPRA) levels have been compared wit…

Supporting the natural gas supply chain public policies through simulation methods: A dynamic performance management approach

2018

Natural gas is considered the transitional fuel par excellence between fossil and renewable sources, considering its low cost, greater efficiency and lesser impact on the environment. This is the reason why its demand levels have increased worldwide, requiring intervention of public and private stakeholders in order to meet these increments. The participation of diverse interconnected stakeholders (key actors) of the supplier-client form, constitutes a supply chain for natural gas, in which the effects of the application of public policy actions can be analysed in the time, using Dynamic Performance Management DPM methodology. The results of the model show the behaviour of the reserves, pro…

Dynamic reconfiguration systems for PV plant: Technical and economic analysis

2020

Solar plants suffer of partial shading and mismatch problems. Without considering the generation of hot spots and the resulting security issues, a monitoring system for the health of a PV plant should be useful to drive a dynamic reconfiguration system (DRS) to solve bottlenecks due to different panels’ shading. Over the years different DRS architectures have been proposed, but no suggestions about costs and benefits have been provided. Starting from technical subjects such as differences of the topologies driving the hardware complexity and number of components, this paper identifies the cost of DRS and its lifetime, and based on these issues it provides an economic analysis for a 6 kWp PV…
