Responding to the need to reduce atmospheric emissions of carbon dioxide, Brown [Brown, D., 2000. A Hot Dry Rock geothermal energy concept utilizing supercritical CO2 instead of water. In: Proceedings of the Twenty-Fifth Workshop on Geothermal Reservoir Engineering, Stanford University, pp. 233–238] proposed a novel enhanced geothermal systems (EGS) concept that would use carbon dioxide (CO2)…
We have analyzed the major activities carried out for geothermal electricity generation since WGC2005. New data have been taken from WGC2010 country update reports, private communications from IGA members and affiliated organizations. Other updates have been collected from websites of private and public organizations involved in geothermal development. Plants commissioned in 2010 (after WGC2010…
Acquisition of geomagnetic field has been done at Kretek, Sanden, Pundong, Bantul and Panggang, Gunung Kidul, Yogjakarta Province on 14 s/d 17 October and 7,8,9,12 November 2009 in orde to interpreted the subsurface structure. Data has been collected by Proton Precession Magnetometer (PPM) to measured the total intensity of magnetic field, Global Positioning System (GPS) to determine the pos…
Berdasarkan data yang dikeluarkan oleh Departemen Energi dan Sumber Daya Mineral, Indonesia diperkirakan memiliki potensi energi panas bumi sebesar 27.000 MW yang tersebar di 256 lokasi [Suyanto]. Jumlah ini menyatakan Indonesia merupakan daerah yang memiliki cadangan energi panas bumi 40% dari total cadangan panas bumi dunia. Paper ini menyajikan hasil penelitian mengenai pengaruh temperatur l…
Geophysics is a part of earth science that studies the Earth using the rules or principles of physics. Geophysicalmethods are divided into several methods, namely: gravity method, geomagnet, seismic, geoelectric andgeoradar.Geothermal energy is stored in the form of hot water or steam at a certain geological conditions at depth.Geothermal system is an area of geothermal or geothermal field is a…
A thermodynamic optimization of the Denizli Kızıldere power plant is performed using real data, and some important results are obtained. The optimum flashing pressure is found to be 200 kPa. According to the existing geothermal power plant, 18% power augmentation is provided when the plant operates at this state. In addition, a new flash-binary model is proposed, and the optimum operating pre…
