2 Agenzia Nazionale per le Nuove Tecnologie, l Energia e lo Sviluppo Economico Sostenibile NationalAgency for New Technologies, Energy and Substainable Economic Development ENEA is a public organization operating in the fields of energy, sustainable economic development and new technologies in order to support competitiveness and sustainable development policies at the national level MISSION: supporting Italian energy policy through the promotion and innovation of sustainable technologies

3 ENEA for Renewable Energy Sources ENEA is carrying out RD&D activities on: Concentrating Solar Power Solar Thermal Photovoltaic Biomass and Bio Fuel Wind Energy (Offshore and small scale) Energy from the sea Hydrogen, Fuel Cells and Storage Systems

4 Concentrating Solar Power (CSP) The ENEA approach Main objectives: To reduce solar electricity cost; To increase solar power performance (higher efficiency); To compensate solar variability with thermal storage; To use thermal fluid environmental friendly and cheap; To promote the development of CSP technology in Italian industry

5 CSP: The ENEA Innovation Use of a new process fluid (high temperature molten salt*, instead of diathermic oil) to improve thermal storage and technicaleconomic performance of parabolic trough CSP plants Molten Salt Storage Hot Tank Molten Salt Storage Cold Tank 550 C 290 C In comparison with oil, this offers: Higher storage capacity (+50%), Higher capacity factor (> 50%), Safer operation Higher efficiency Lower storage and electricity cost Power Block: Steam & Electricity Generation and involves: New high temp. technology for solar collectors and heat receivers Molten salt system management * KNO 3 /NaNO 3

6 Molten salt as process fluid and thermal storage Molten salt (60% NaNO 3 40% KNO 3 ) Advantages: High working temperature (air stable up to 600 C) Minimizes volume( 50%) and cost of the thermal storage (high thermal capacity ) Less expensive than synthetic oil and environmental friendly Atmospheric pressure in the thermal storage Common used as a fertilizer
