Professor Jeff Tester
Professor Jeff Tester is one of the world’s foremost authorities on enhanced geothermal systems and is the David Croll Professor of Sustainable Energy Systems in the School of Chemical and Biomolecular Engineering at Cornell University. He is also the Director of the Energy Institute in the College of Engineering and Associate Director of the Cornell Center for a Sustainable Future, with special responsibility for the energy focus of CCSF. Professor Tester’s research spans almost every discipline concerned with the production of electricity from geothermal resources. He was the senior author of the landmark study The Future of Geothermal Energy – Impact of Enhanced Geothermal Systems (EGS) on the United States in the 21st Century, a report prepared by an MIT-led interdisciplinary panel for the US Department of Energy. He has lectured widely and gave evidence before the House of Representatives inquiry on Renewable Energy.
Dr Tony Batchelor
Dr Tony Batchelor is Chairman and Managing Director of GeoScience Ltd and EarthEnergy Ltd, specialised geothermal and geotechnical consulting companies in the UK. He is a Mining Engineer who taught rock mechanics at the Camborne School of Mines for 12 years and developed the UK Hot Dry Rock Geothermal project at Rosemanowes, where he was project Director from 1977 to 1986. With GeoScience Ltd he has worked on geothermal projects around the world, including Japan, Turkey, Indonesia and the USA. The GeoScience subsidiary company, EarthEnergy, is the market leader in geothermal heat pump installations in the UK. Tony was a founding member of the International Geothermal Association (IGA) and has served on the IGA Board. He lectures on Geothermal Energy at the Universities of Cambridge and Exeter and is the author or contributor to more than 60 scientific papers and books on rock mechanics and geothermal energy. In 2005 he was a member of the team for the MIT Study, ‘The Future of Geothermal Energy’ and in 2007 gave the ‘Geothermal Energy, Present and Future’ address to the 200th Anniversary Meeting of The Geological Society of London.
Dr Roy Baria
Dr Roy Baria has over 30 years experience in ‘hot rocks’ geothermal projects and currently consults to geothermal companies worldwide. He is Vice President (Science & Technology) at AltaRock Energy Inc and is also Task Leader for the Enhanced Geothermal Systems Annex of the International Energy Agency. For 14 years from 1976 he was a key researcher and ultimately Deputy Project Director at the Rosemanowes project in Cornwall, involved in resource assessment, seismic monitoring of hydraulic stimulations (which he pioneered), high temperature instrumentation, and cross-hole & vertical seismic profile surveys.
In 1990, Roy joined the European Hot Dry Rock geothermal program at Soultz, France as Chief Scientist and project coordinator, a role he held until 2004. Over that period, the project drilled and hydraulically stimulated a number of deep (5,000 m), hot (200°C) wells, and established underground circulation. These are critical steps in the development of Enhanced Geothermal Power projects. Roy resides in England & France and has organised four International Conferences on HDR, is an author and contributor to many papers and forums devoted to geothermal energy. He represented IEA/GIA on the HDR technology at the Intergovernmental Panel on Climate Change (IPCC) in Lubeck, Germany.
