  1. EFFICIENT LOW TEMPERATURE GEOTHERMAL BINARY POWER LOW-BIN PROJECT - DG-TREN IMPROVING EGS EXPLOITATION COSTS by Dr. C. Karytsas and D. Mendrinos Centre for Renewable Energy Sources February 2006

  2. LOW-BIN PROJECT AIMS IN IMPROVING • Cost effectiveness • Competitiveness • Further market penetration of geothermal electricity generation

  3. Widening market perspectives of Geothermal Rankine Cycle • Power generation from low temperature geothermal resources with temperature threshold at 65oC (currently 90-100oC) • Developing a CHP machine with heat recovery from the cooling circuit with total energy efficiency of 98-99% (currently 7-15%)

  4. The LOW-BIN project involves: • Theoretical research • Laboratory experimentation • 2 Pre-prototypes development • Evaluation in terms of technology breakthrough achievement • Evaluation in terms of energy efficiency • Electricity generation costs and market potential • Successful prototypes manufacturing and demonstration • Monitoring, validation as well as technology dissemination and other innovation related activities

  5. The LOW-BIN project consortium: • CRES (Greece-Coordinator) • TURBODEN (Italy) • GFZ-Potsdam (Germany) • GEOTEAM (Austria) • University of Oradea (Romania) • ESTSetubal (Portugal) • Politecnico di Milano (Italy) • BRGM (France) • ISOR (Iceland)

  6. LOW-BIN Budget distribution Total budget : 3,935,713 € EU Funding : 1,878,812 € (47,74%) • R&D activities : 13.70% • Demonstration : 74.50% • Innovation related activities : 8.46%

  7. * including residual energy from higher temperature resources * estimation based on data from the “Atlas of Geothermal Resources in Europe”, 1st and 2nd editions, as well as on published data in the scientific literature and the Internet * main assumptions: in 25 years (economic plant life) 25% of the heat stored in the hot water / steam producing horizons, present in depths less than 3km, is recovered. ¹ conversion efficiency according to the technology under development within the LOW-BIN project.
