Estimation of Theoretical and Technical Potentials of Geothermal Power Generation using Enhanced Geothermal System

Small Capacity Geothermal Binary Power Generation System

Japan is a volcanic country having abundant geothermal resources. To date, Japan has 20 geothermal power generation facilities, with a total installed capacity of 550 MW. Most of these facilities are large capacity geothermal power plants constructed by utility power companies, but due to various circumstances, there are no further plans to build large capacity plants in the near future. The Ne...

Power Generation Potentials of Major Geothermal Fields in Turkey

In this study, potential of electrical power generation estimates for geothermal resource fields with sufficient information available in Turkey are calculated. Estimates are obtained using the methodology based on volumetric reserve estimation approach introduced by USGS. A stochastic approach using Monte Carlo simulation technique is implemented to account for uncertainties involving some inp...

Designing multi-well layout for enhanced geothermal system to better exploit hot dry rock geothermal energy

Heat extraction mode, e.g. well layout or arrangement of wells, of enhanced or engineered geothermal system (EGS) is crucial to its performance and directly affects its commercial viability. Assuming the subsurface target hot dry rock (HDR) has been well-fractured and the created heat reservoir can be treated as a homogeneous porous medium, we numerically simulate the long-term heat extraction ...

Solar-Enhanced Air-Cooled Heat Exchangers for Geothermal Power Plants

This paper focuses on the optimization of a Solar-Enhanced Natural-Draft Dry-Cooling Tower (SENDDCT), originally designed by the Queensland Geothermal Energy Centre of Excellence (QGECE), as the air-cooled condenser of a geothermal power plant. The conventional method of heat transfer augmentation through fin-assisted area extension is compared with a metal foam-wrapped tube bundle. Both lead t...
