2 INTRODUCTION Adesso Energia is an innovative startup based in Palermo created by people who have been working in the field of renewable energies that have had the insight to bet on the integration of more renewable energy in order to fill the gaps related to the exploitation of each of them and consistently produce more clean energy. Using the experience gained and involving research institutions, skilled technicians and several companies operating in the sector, was born so the hybrid system " AE BIO SOLAR ". DESCRIPTION " AE BIO SOLAR " is an innovative system for the continuous production and combined electricity that integrates the heat collected from the SOURCE SOLAR and the thermal energy produced by the combustion of BIOMASS. PROJECT OUTLINE Pagina 2

3 HOW DOES THIS WORK The hybrid system " AE BIO SOLAR " has been engineered for the production of electricity through a closed circuit (ORC turbine) that, by means of a rankine cycle at low temperature ( 165 C ), exploits the thermal energy collected by the solar source ( solar field ) and the thermal energy produced by biomass burning ( boiler ). The main components of the system are thus: SOLAR FIELD, BOILER AND TURBINE. These components were specifically designed and sized by three different Italian companies consolidated experience according to the characteristics required for the realization of the project. The SOLAR FIELD consists of parabolic troughs in the number necessary to cover between 20 and 40% of the heat output of the system based on the power required. A concentrator is formed by curved mirrors of parabolic shape positioned north / south with tracking system east / west to maximize solar collection during the day. The mirrors reflect the sunlight and, thanks to their parabolic shape, the focus on a point where the receiver tube. The heat transfer fluid consisting of thermal oil which circulates inside the receiver tube is then heated to the desired temperature of at least 145 C. Only at this temperature the thermal oil will come to a heat exchanger with the purpose to bring the same temperature as the fluid carrier of the main system and that is " water ". It will then be the task of the BOILER energize the same " water " up to 165 C, the optimum temperature for the production of electricity with the " AE BIO SOLAR ". If the temperature of the carrier fluid coming from the solar field will not reach the minimum requirement (such as at night for example ) will be only the boiler, directly and constantly, through most biomass combustion, will maintain the temperature required by the system. The boiler, so even without the contribution of thermal energy from the solar field, constantly provide water at a temperature of 165 C to a closed circuit ORC ( TURBINE ) through a heat exchanger with fluid inside, a special organic biodegradable and non-toxic. This special fluid, entering into boiling at temperatures far lower than that of water, produces highpressure gas whose expansion turbine that moves the sliding the rotor of a generator produces electricity that can be self-consumed or injected into the network. At the exit of the turbine working fluid, even in gaseous form, is brought to a condenser where it transfers excess heat and returns to being a liquid ready to be pumped back in the closed circuit. The excess heat released in the condenser is still usable thermal energy for preheating or drying of the biomass (CAR ). Despite the three main components of the system ( solar field, boiler and turbine ) are provided with specific control panels for the automated management of its process, the entire property is managed and controlled from a distance by the innovative system SCADA (Supervisory Control and Data Acquisition) that, through special application software and dedicated sensors, to ensure perfect integration and operation of all the elements.

5 SPECIAL SYSTEM AE BIO SOLAR " Given the considerable interest, the system "AE BIO SOLAR" is now in the process of patenting internationally. Its main characteristics are : It's an innovative system for the continuous and combined production heat and power; Take advantage of solar energy up to 3200 hours per year and the energy for the combustion of biomass for other 5800 hours. Total production 8000 hours per year of 8760; Respect the environment because it uses to produce energy as the main carrier fluid " water " to the maximum temperature of 165 C; Working at low temperature no need for specialized personnel; It s a plant in High Efficiency Cogeneration; It s can turn into a trigeneration plant for air conditioning and refrigeration; It may be only to biomass or solar; It works with various types of biomass; It can be integrated by burning methane gas; The main components of the system (solar field, boiler and turbine) are constructed and sized specifically by Italian companies of primary and consolidated experience that ensure their good accordance with applicable law; The entire property is managed and controlled from a distance by the innovative system SCADA (Supervisory Control And Data Acquisition) which will ensure the proper functioning of the system. BIOMASS FOR BURNING The system, in addition to exploiting the sun's energy ensures stable operation through the burning of biomass derived from agricultural waste such as wood pellets, wood chips, husks, shells, cereals, etc. Depending on the calorific value and the costs to be incurred is preferable to use the anhydrous exhausted pomace olive Energy which now can ensure the provision of all that needed to operate the plant. TYPE OF PLANTS AND STAKEHOLDERS Adesso Energia has already drawn up plans to install systems "AE BIO SOLAR" with power from 50kWe and until the creation of the so-called large plant also of several megawatts. Those who are now interested in doing this type of system are small, medium and large investors, farms, public agencies and all those structures that need also of thermal energy to heat or cool environments such as hospitals, hotels, super markets, etc. Pagina 5

6 HOW MUCH ELECTRICITY AND HEAT PRODUCES To make clear the potential of the "BIO SOLAR AE" is below, illustrate the data related to plants with a power of 200kw and 1 mw: AE BIO SOLAR hours of annual production of Kw 1Mw Production from solar (3.200 hours) 40% Kwe Production from biomass (4.800 hours) 60% Kwe Total electricity production year 100% Kwe Thermal Production (hour) Kcal/h The heat output may also be used to heat or cool environments. Here in Italy the system also benefits from the incentives provided for white certificates. With the examples of production reported above provides the basis for a correct evaluation of the investment to adapt to the expected benefits in every single country in the world. In Italy the plants are allowed up to 200kw with simplified procedures and therefore be suggested to invest in the building of this power multiple systems rather than one of the largest size. INVESTING IN ITALY WITH THE "AE BIO SOLAR" The plant meets the specifications required by current legislation in Italy for the granting of two types of incentives combined. The incentives for the part thermodynamics are provided and fixed for 25 years, and combined with the selling price of the energy fed into the grid. The incentives for the part of the combustion are valid for 20 years and paid through a comprehensive tariff. Moreover, if the heat produced by the cogenerated is also used for other uses (heating, cooling, etc.), you get the certification, high capacity (CAR) that allows you to also enjoy the benefits involved in the white certificates. According to Italian law the return on investment in the system "AE BIO SOLAR" takes place in a maximum of 6 years and the total profit for the duration of the incentive comes to 350 %. Pagina 6
