GEOLEC Final Conference ORC technology for geothermal electricity: where we are? Joseph Bonafin Turboden Geothermal Sales Marco Baresi Turboden Institutional Relations Pisa, 05 th June 2013
About us Turboden is a leading European company in development and production of ORC (Organic Rankine Cycle) turbogenerators. This state of the art equipment generates heat and power from renewable sources and heat recovery in industrial processes. The company was founded in 1980 in Milan by Prof. Mario Gaia, Professor of Energy at the Politecnico di Milano, and today Managing Director of Turboden. His close connection with the university has always ensured the recruitment of highly qualified R&D personnel. Turboden has always had a single mission: design ORC turbogenerators for the production of heat and electrical power from renewable sources, while constantly striving to implement ORC technical solutions. In 2009, Turboden became part of Pratt & Whitney Power Systems (UTC Corp.), a worldwide leader in development, production and service for aero engines, aerospace drive systems and power generation gas turbines, to develop ORC solutions from renewable sources and waste heat worldwide. In 2013 MHI acquires Pratt & Whitney Power Systems (now PW Power Systems, Inc.) and the affiliate Turboden. Today Turboden s.r.l. and PW Power Systems, Inc. are Mitsubishi Heavy Industries group companies, with whom MHI will be able to provide a wider range of products and services for thermal power generation systems. 2
What we do Biomass Geothermal electricity Solar heat Waste-heat Turboden designs and develops turbogenerators based on the Organic Rankine Cycle (ORC), a technology for the combined generation of heat and electrical power from various renewable sources, particularly suitable for distributed generation. standard units from 200 kw to 10 MW customized solutions up to 15 MW 3

Germany Italy: comparative analysis Driver Germany Italy Political willingness EU obligations (Dir. 2009/28/CE) Incentive scheme Boost since 2000 2020 Geothermal target: Additional ~ 300 MW (no tradition, deep drilling, no steam) 250 /MWh for 20 years +50 /MWh if stable EGS Timing 2007 projects 2010 contracts 2012 start-up (3-6 months authorization) Mineral risk management Helped by public intervention National Energy Strategy: insufficient relevance 2020 geothermal target: Additional ~200 MW (tradition since early 900, shallow drilling, dry/flash steam) 159 /MWh (register) 230 /MWh (50MW) ~3% total incentive RES/year After 2015? Pilot project - MiSE Regional regulations No guideline, no homogeneity Barrier against development Finance Financially structured subjects Pre-authorization phase with own resources Risky investments Technological development Leading element in the RES policy Geothermal since early 900. ORC cross technology (biomass, HR, CSP) Industrial boost (export) Training Information Leading element in the RES policy More social acceptability and dissemination: wiki «geothermie» pag.17 Made in Italy: excellence in all the supply chain (exploration, drilling, power block, management) 7 Inadeguate information and hostility: wiki «geotermia» pag. 1
Proposals for the Italian context More valorization of national technology: to boost the industrial system How to improve D.M. 6/07/2012: e.g. extension of incentive tariffs until 2020 (stability for investment) To develop financial scheme for investments (e.g. EIB funds) Support/public guarantee for pre-investment phase Training and information campaign More valorization for the Italian export R&D support for geothermal technology 8
