  • 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 ...

  • Dynamic simulation and 2D multiple scales and multiple sources within basin geothermal field

    In order to accurately describe the geothermal field within a basin, it is necessary to divide it into the normal geothermal field and additional geothermal field. For the accuracy by describing of the additional geothermal field, grids need to be increased. Traditional unequal interval difference method can be used to solve this problem, which has to increase grids within the unnecessary area, ...

  • Impacts of Shallow Geothermal Energy on Groundwater Quality

    The use of shallow geothermal energy (SGE) systems to acclimatize buildings has increased exponentially in the Netherlands and worldwide. In certain areas, SGE systems are constructed in aquifers also used for drinking water supply raising the question of potential groundwater quality impact. Impacts of Shallow Geothermal Energy on Groundwater Quality provides a hydrochemical and geomicrobial ...

  • Effect of Non-Condensable Gases on geothermal power plant performance. Case study: Kizildere Geothermal Power Plant-Turkey

    Non-Condensable Gases (NCGs) are natural components of geothermal fluids, and they are a source of considerable capital and operating costs for power plants. The NCG content of geothermal steam varies over the world from almost zero to as much as 25% (wt). In this work, the influence of NCGs on the thermodynamic performance of geothermal power plants is analysed for various NCG content and ...

  • Artificial geothermal energy potential of steam-flooded heavy oil reservoirs

    This paper explores the concept of harnessing geothermal energy from heavy oil fields that have undergone steam flooding and so accumulated substantial heat from steam injection. Once the steam flooding process reaches economic cut-off resulting from high water cut and/or high steam-to-oil ratio, the reservoir would be abandoned, leaving behind stored energy in the form of heat. From this point, ...

  • Performance optimisation of the combined single flash binary geothermal power plant

    In this paper, the optimal operating conditions of a hypothetical combined single flash-binary geothermal power plant are investigated and performance analyses are performed based on Aydin-Germencik field in Turkey. The relationship between flashing pressure, turbine inlet pressure of the binary cycle and total heat transfer area of the heat exchanger are determined for maximum power output of ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A Cleaner Energy Future

    As renewable energy plays an increasingly important role in the world’s energy portfolio, the standards of ASTM International Committee E44 are helping to pave the way for innovation in clean energy sources. A growing population and improving living standards around the world are causing significant increases in energy demand and competition for fossil fuels. These escalating energy ...

  • Renewable energy and energy efficiency in Bulgaria

    The interest in renewable energy sources (RESs) utilisation and energy efficiency improvement programmes in Bulgaria reflects the changes in the field of energy policy worldwide and in Europe. Now energy management becomes a great problem of inner policy of Bulgarian government. In the last few years there has been a growing attention to the RESs applications. Bulgaria has one of Southern ...

  • Renewable Energy - A Key Solution to End Global Warming

    Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane and carbon dioxide (CO2) in the atmosphere. These ...

  • Building New Industries and Creating New Jobs in a Plan B Economy

    Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

  • 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 ...

  • Africa’s green energy challenge: Mega projects, off-grid or somewhere in between?

    South of the Sahara, getting electricity to 620 million people may require an all-of-the-above strategy. A 310-megawatt wind farm sprouting up in a remote, barren landscape near Lake Turkana in northern Kenya has the clean energy world buzzing — and for good reason. Africa’s largest wind farm, with 365 towering turbines, is creating more than 500 stable jobs in an ...
