  • Tidal power - A different perspective

    Kepler Energy is taking a different approach to tidal power, applying a design that can be used in benign sea conditions in a location closer to end-demand and which could generate utility-scale quantities of power, as Peter Dixon explains.The physical environment of tidal turbines is clearly very different to that of wind turbines, not least because water is a lot denser than air! However, ...

  • Prime Power Generation - Case Study

    A national electricity grid must always be able to meet the needs of its users. This requires it to be: stable, maintaining the required electrical frequency (50 Hz in the UK); balanced, continuously matching supply to demand; and adequate, ensuring total generation capacity is never outstripped by demand. ...

  • What rural Alaska can teach the world about renewable energy

    I flew into Unalakleet, Alaska, on a late fall day. With about 700 people, Unalakleet is large by rural Alaska standards and serves as a regional hub. The village is located on a sandy spit of land where a clear river meets the turbid water of the Bering Sea. Out the plane window the sun shone bright, glittering off the wind-tossed whitecaps of the sea. To the east, the rolling Nulato Hills, clad ...

  • Ocean Thermal Energy Conversion Coming To An Island Near You

    Ocean Thermal Energy (OTE) Corporation may be landlocked in Lancaster, Pennsylvania, but that isn’t stopping them from looking to the ocean for 24/7 electricity. Their primary technology is Ocean Thermal Energy Conversion (OTEC), which uses the temperature differentials in the ocean to produce steam. The steam, in turn, activates a turbine, which generates clean energy and potable water. ...

  • Geothermal plant protects pumps - case study

    This large geothermal company needed reliable equipment in the deserts of southeastern California. Geothermal plants turn water into to steam to drive turbines. Protecting the pumps is paramount. Keeping the inflowing water clean of debris and marine life, an IWS traveling water screen provides reliable removal with minimal labor. Debris is lifted from the water, and dropped directly into a ...
