  • What’s geothermal again?

    Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

  • Nevada Geothermal, Ormat to develop Oregon resource

    Nevada Geothermal Power Inc. (Vancouver, B.C.) and Ormat Nevada Inc., a subsidiary of Ormat Technologies Inc. (Reno, NV), have signed an agreement under which the two companies will jointly develop, construct, own, and operate one or more geothermal power plants at the Crump Geyser Project Area in Lake County, Oregon. The agreement calls for the formation of a limited liability company, ...

  • 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 ...

  • 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.' ...

  • 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 ...
