Today producing energy has never been so easy and convenient. Thanks to the state incentives of systems below 200Kwe, renewable energy production systems are the solution to the economic problems related to the energy of our country.
Finenergy provides assistance and consultation, for everything related to the design, construction and installation for energy production plants from renewable sources, both electrical and thermal.
Biomass systems can be divided into three main categories:
The vegetable oil used as fuel, is certainly a renewable source and is synonymous with clean energy. Cogeneration is a joint production of electrical (or mechanical) energy and useful heat from the same primary source.
Cogeneration, using the same fuel for two different purposes, aims at a more efficient use of primary energy, with relative economic savings especially in production processes where there is a strong contemporaneity between electric samples and thermal samples.
The first advantage of cogeneration is obviously economical: a properly sized cogeneration system allows high energy savings of around 25-40%, and an investment pay-back around 36-48 months. Cogeneration allows to achieve yields of 70-85%, a significant value compared to 50-60% of new systems with a combined cycle for the only electricity production.
Like all biomass plants, vegetable oil systems allow to cover the energy needs during peak hours. In fact are these that today are still covered by fossil fuels and therefore more subject to price increases.
The wood-cellulosic biomasses are biomasses composed mainly of lignin and cellulose, which may come from the forestry sector as leftovers of woodland utilization, or as waste from wood processing industries, pruning waste and production of dedicated wood crops. Depending on the type of use, the wood fuel needs more or less processing processes. Shredding and chipping operations are sufficient for combustion in large-scale power generation plants.
The wood chips is obtained by crumbling or chipping the wood cut through special chipping machines; it’s used the scraps of the cuts in the woods but also the pruning of the city trees. The woodchips are generally marketed with a moisture standard higher than the wood logs, varying between 35% and 45% calculated on the dry. Indicatively the wood chips have a calorific value lower than (3 / 3.6) kWh / kg.
Like all biomass, wood can cover the energy needs during peak hours. In fact arethese that today are still covered by fossil fuels and therefore more subject to price increases.
The production of Biogas takes place during the anaerobic fermentation of organic substances and its composition is: Methane (CH4) approx. 55% - Carbon Dioxide (CO2) approx. 40% - Water Vapor approx. 3% - Other Substance approx. 2% . Recent technologies make it possible to get back energy from zootechnical effluent of pig, bovine and sheep livestock. This is allowed thanks to the possibility of converting the biogas deriving from anaerobic fermentation, into electrical and thermal energy. The Biogas production mechanism is a biological process by which the organic substance is transformed into Biogas. Who produces Electricity from Biogas has the right to obtain the government incentive called green certificates and that is recognized by the National Electricity Grid Operator (GSE) thanks to the classification of the "IARF" type system. The Finenergy offer is economically competitive and suitable for medium-small farms. Any hypothetical intervention, in case there are already collection tanks, consists of: Covering the tanks with double membrane gasometer.

Like all biomasses, the Biogas allows to cover the energy needs during peak hours. In fact are these that today are still covered by fossil fuels and therefore more subject to price increases.
Natural gas is a great opportunity for the simultaneously production of thermal and electrical energy and to achieve significant energy SAVINGS and reduce CO2 emissions in the environment. Finenergy supplies Cogenerative groups powered by gas from a minimum of 5 KwE to a maximum of 500 KwE with the Brand COGAS, TURNKEY.
A BIT OF HISTORY: In a manuscript by the Chinese historian Chang Qu, dated 347 B.C., a strange gas is described that can be used to illuminate. About 200 years ago, Alessandro Volta "rediscovered" the energy potential of natural gas, noting the small gaseous bubbles that formed by moving the filthy bottoms of Lake Maggiore. Approaching a lit match, in fact, the gas contained in the bubbles fed a bluish flame.
Between 1840 and 1850, the gas lighting became common in many American and European cities, at the point of changing the lifestyles of the citizens: the streets, good lit even in the evening, discouraged thieves, prospered dance halls and meeting places also for the less well-to-do people (since the lower cost of gas lighting compared to candles). However, these advantages remained confined where natural gas spontaneously surfaced, as there were still no adequate technologies for research, extraction and transport.
For a long time the natural gas that came out of the oil wells was burned by a torch or released into the atmosphere as soon as it came to the surface. So many billions of cubic meters of natural gas went up in smoke: one of the greatest waste of resources that history recalls, and a serious damage to the environment, but it was still far from an environmental awareness. Italy is one of the few countries where methane has been valued as an energy resource, since the early years of the discovery of the deposits in the Padana Valley and in the Adriatic Sea. Methane, as a source of national energy, has made a significant contribution to the industrial development of the country in the fifties and sixties.
In general, the exploitation of methane began only recently: in Europe a little over 50 years ago, with the development of technologies that would make it economically advantageous for mining and with a network of methane pipelines (ie the pipelines that bring the methane from the place extraction to consumption) for easier distribution. The whole of Europe is currently crossed by methane pipelines, an ideal transport system because it has a low environmental impact: it does not increase traffic on the surface and cannot be seen, thanks to the reconstruction of the surrounding environment after the excavation for the laying of the pipes.
