Low-Enthalpy Geothermal Resources for Power Generation

Dornadula Chandraskharam (1948, India) is the Head of the Centre of Studies in Resources Engineering, Indian Institute of Technology Bombay. He has been working in the fields of volcanology, groundwater pollution, and geothermics for the past 25 years. Prof. Chandrasekharam conducted research on low enthalpy geothermal resources in India and is currently the Chairman of M/s GeoSyndicate Power Private Ltd., the only geothermal company in India. He is one of the executive members of the International Society of Groundwater for Sustainable Development (ISGSD). Jochen Bundschuh (1960, Germany) is working in geothermics, subsurface- and surface hydrology and integrated water resources management, and connected disciplines. In 2001 he was appointed to the Integrated Expert Program of CIM (GTZ/BA), Frankfurt, Germany and works within the framework of the German governmental cooperation as adviser in mission to Costa Rica at the Instituto Costarricense de Electricidad (ICE). In 2005, he was appointed as affiliate professor of the Royal Institute of Technology, Stockholm, Sweden. He is elected Vice-President of the International Society of Groundwater for Sustainable Development.

"The forte of the book is the part dealing with modern methodology and techniques of exploring the geothermal resources, and beneficially converting the heat energy of geothermal waters into electricity. It offers solutions for generation of power that would ensure that no greenhouse gases are formed. In other words, tapping the energy of hot-springs on a large-scale implies effective contribution to the lessening of global warming."In: CURRENT SCIENCE, VOL. 95, NO. 12. DECEMBER 2008“… case studies described in this book clearly demonstrate how low-enthalpy geothermal resources can be utilized for improving the socio-economic status of rural areas in developing countries.”“This book is intended not only for graduate and research students as a primary dictionary, but also should prove useful for professional geologists and engineers, as well as professionals involved in energy planning and greenhouse gas mitigation.” in: ENERGY SOURCES, Part A, 31:98, 2009
