  • 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.' ...

  • Design of method and mechanism for geothermal energy extraction

    By drilling using a specially designed hydride carbide (melting point: 1,365°C) drill, we can drill the earth's crust to about 5 to 40 km to reach temperatures of 700 to 1,000°C, with minimum cost of the drill and drilling technology. Further, we can extract energy by pouring in water on an inserted carbide alloy vessel into the drilled well and bringing out as steam to drive the turbines. By ...

  • Regional geological recognition for the implementation of a urban geothermal concept

    A reflection seismic survey was performed in the city of Lausanne (CH) to map geological layers relevant to geothermal energy production. By using a wireless seismic system and a powerful seismic vibrator source we were able to high quality results despite the presence of elevated urban noise levels. The new subsurface maps allow the estimation of the geothermal potential for the city of ...

  • Geothermal Power Approaches 12,000 Megawatts Worldwide

    In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal’s best year since the ...

  • Modeling geothermal wells using SVHeat and SVFlux

    Numerical modeling of geothermal processes has received increased attention in recent years. The process of installing geothermal heating systems in residential homes and cottages is one application of numerical models. These systems typically involve drilling between one and three wells on a particular property. Heat exchangers then act as a pump and remove heat from the ground in order to heat ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...

  • A BME solution of the stochastic three-dimensional Laplace equation representing a geothermal field subject to site-specific information

    This work develops a model of the geothermal field in the Nea Kessani region (Greece) by means of the Bayesian maximum entropy (BME) method, which describes the temperature variations across space in the underground geological formations. The geothermal field is formed by a thermal reservoir consisting of arcosic sandstones. The temperature distribution vs depth was first investigated by the ...

    GeoSmart Energy has acquired a time-saving multi-loop and pump handler designed for geothermal drilling. The GeoSmart Push'N Pull simplifies the installation of geothermal pipes in vertical drill applications, saving time, money and manual labour. "Geothermal drillers will appreciate its'push'factor for inserting pipe while water well drillers will love its 'pull' factor for extracting pumps ...

  • Case Study - Aluto Langano Power Plant Rehabilitation

    Aluto Langano, Ethiopia – 2007 The Aluto Langano Geothermal Pilot Plant (ALGPP) is located on the Aluto volcanic complex of the Ethiopian Rift valley, close to the eastern escarpment between Lake Langano and Lake Ziway, some 200 km southeast of Addis Ababa. The Aluto volcanic complex is a young acidic system consisting of domes, lava, and pyroclastic interbeds. The geothermal field was ...

  • Case Study - 6MW Non-Condensing Power Plant

    Lihir Island, Papua New Guinea – 2003 First Geothermal Power Station in PNG: Press Release, April 16, 2003 Lihir Gold Limited “Gold company Lihir Gold Limited is turning its vast geothermal resource into an opportunity. In April, the company started commissioning a 6MW geothermal power station, the first in Papua New Guinea to use natural geothermal ...

  • Fossil Fuel Development in the Arctic is a Bad Investment

    Even master chess players can miss a great move when they have been primed to look for a different one. To explore this phenomenon, researchers tracked master chess players’ eye movements when given chessboards with different layouts. With the first board, players could reach checkmate using a familiar move. When given the second chessboard, the players' eyes kept looking at the pieces ...

  • Insurance for Crossing the Valley of Death

    To achieve a modest reduction in atmospheric carbon dioxide emissions, global investment in renewable energy assets would need to increase from current levels of about $100 billion per year to $500 billion per year. Some of this increase can be accomplished by investment in existing, commercially proven technologies; but to meet the challenge of rapidly scaling renewable energy, we also need to ...

  • Run cars on green electricity, not natural gas

    With the dramatic increase in oil prices earlier this year translating into higher prices at the gas pump in the United States, concerns over US dependence on foreign oil are once again part of the national discussion on energy security. Combined with the growing understanding that carbon emissions from the combustion of fossil fuels are driving global climate change, the debate is now focused on ...

  • The Global Arc Towards Renewable Energy

    Introduction Given the United States’ recent election results, America’s future on climate and energy policy is uncertain, but global progress on mitigating climate change will continue with or without us. We have reason to be optimistic because countries around the world have demonstrated their commitments to taking action on global warming. Already, 114 countries have ...
