Economic assessment of nine geothermal direct use applications. Final report

This report provides an economic analysis of nine federally-supported geothermal direct heat applications which were part of DOE's Program Opportunity Notice (PON) program. Three of the projects analyzed were user-owned systems, and six were district heating systems. Five of the nine projects are successful from an economic standpoint and the majority of these projects are in areas where geothermal energy has long been used for heating. The results of this analysis indicate that geothermal energy projects can be economic under certain conditions, but these conditions may not be very widespread
