  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • H2S Emissions Control at Geothermal Plants

    The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a turbine to ...

  • Rational use and management of geothermal energy resources

    This article identifies and explains several attributes of geothermal energy. High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Case Study - 2.0 MW Nominal Geothermal Power Plant

    Lake Naivasha, Kenya – 2007 Under a contract signed in June 2006 with Oserian, Geothermal Development Associates (GDA) agreed to design, manufacture, inspect, test, pack, and ship a 2 MW nominal geothermal steam turbine generator and related power plant auxiliary components from Reno, Nevada, USA to the Oserian flower-growing facility near Lake Naivasha, Kenya. GDA will provide technical ...

  • Determining the circulation depth of thermal springs in the southern Rocky Mountain Trench, south-eastern British Columbia, Canada using geothermometry and borehole temperature logs

    Geochemical data for thermal spring waters along the southern Rocky Mountain Trench in British Columbia, Canada were examined. The range of equilibration temperatures for the thermal springs is between 24 and 59°C, assuming that there is minimal mixing with colder shallow waters that might lead to a lowering of the calculated equilibration temperature. The chalcedony geothermometer is found to be ...

  • Limitation of hardness from thermal water by means of nanofiltration

    Geothermal conditions are extremely favourable in Hungary. Thermal water is accessible in 70% of the territory of the country, with a lowest temperature of 30°C. For energetic purposes, it can be utilized in two different ways: for supplying heat or generating electricity. In relation to utilization, one of the most serious problems derives from the chemical composition of thermal ...
