A Proposed New Geothermal Power Classification System

Abstract

Multiple classification schemes have been devised to explain and categorize geothermal energy systems. Example classifications include those developed by the United States Geological Survey, National Renewable Energy Laboratory, and through a study conducted at the Massachusetts Institute of Technology. These classification systems have mixed geology, engineering, and resource terminology together in a manner that is difficult to present to an investor or to someone not familiar with the geothermal industry. Neither are these classifications conducive as a generalized exploration tool that relate the heat and moveable water to a geologic province or feature as a potential exploration target. This paper presents a first attempt at developing a broad geothermal power classification system that structures various parameters impacting geothermal development to the geological environment.
