Personal Account: Stanford Geothermal Workshop
AltaRock Energy’s Matt Uddenberg accompanied a group of staff to this year’s Stanford Geothermal Conference, where AltaRock’s Susan Petty and Trenton Cladouhos gave a presentation on the Newberry EGS Demonstration. This was Matt’s first experience with the workshop, so we asked him to share his experience. Why I Went I was fortunate enough to have my first experience ...

Case Study - 2.4 MW Geothermal Wellhead Power Plant
Eburru, Kenya – 2012 Under a contract with Kenya Electricity Generating Company (KenGen), GDA designed, manufactured, tested, and shipped all of the major equipment for a 2.4 MW wellhead power plant at Eburru, Kenya. GDA also provided supervision and technical support during installation and commissioning of the plant. At the heart of the plant is an Elliott 8-stage GYR turbine. This ...

The right mix: the Philippines achieving its renewable energy goals
The global energy system is undergoing a transition from fossil fuels to renewable energy. There are clear signs that the pace of change is accelerating. 2009 was the second year in a row that more money was invested worldwide in renewable electricity generation projects than in fossil fuel-powered plants, according to data published by the United Nations. Developing countries, especially in ...

World geothermal power generation nearing eruption
With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth’s heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total ...

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 ...

Hydrogen as transport fuel in Iceland. The political, technological and commercial story of ECTOS
Through the political, the technological and the commercial story of the early phases of the ECTOS project and its background, the implementation of hydrogen as transport fuel in Iceland is analysed. The presence of large amounts of geothermal energy is the resource basis for the governmental plans for converting Iceland into a hydrogen economy. Strong political commitment has established the ...

Exergy analysis and pressure optimisation of geothermal binary power plants
Binary geothermal power plants are used for power production from moderate temperature geothermal reservoirs (85-170°C). In performance analysis of those plants, the second law of thermodynamics is used like in other conventional power plants. In this paper, the exergy analysis and pressure optimisation methods are described for binary power plants. The method described is applied to a ...

Evaluation of utilisation opportunities of geothermal energy in the Kavala region, Greece, using exergy analysis
Greece has a lot of geothermal energy fields. Due to legal inefficiencies, the exploitation of this renewable energy source remains at very low levels. In this work, the operation of a cogeneration (hot water and electricity) geothermal plant that could be built in Eratino, Greece, is analysed. The research on the development of a low enthalpy geothermal field is investigated as a very essential ...

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 ...
