  • 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, ...

  • 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. ...

  • 2014 JRC Ocean Energy Status Report

    Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short ...

  • Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

    This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems primary aim is to achieve a low distortion, high ...

  • Cavitation leads to perfect mixes

    Development of accurate classification of cavitation types, as well as any classification, has to be based on a choice of general summary classification signs. For example, it can be different by constructive signs of work parts, by character of a course of process, by cavities types and other general classification signs. In present time distinguish the following types of cavitation: static, ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • Ocean Thermal Energy Corporation and Alden complete DOE-funded environmental feasibility study of OTEC in Hawaii

    The U.S. Department of Energy recently released the final report for an OTEC project titled “The Potential Impacts of OTEC Intakes on Aquatic Organisms at an OTEC Site under Development on Kauai, HI”. OTE Corp and Alden were the principal investigators and Tenera Environmental and AECOS assisted with the fieldwork and processing of the samples. The report includes both an evaluation ...

  • Ocean Thermal Energy conversion and the company bringing it to market: clean water for our children

    Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favourite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water. This liquid of life keeps us hydrated, catalyses crucial chemical reactions within our cells ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

  • Zero emissions day: What it is and why we need it

    Today is September the 21st – a day that didn’t hold any particular significance until a simple observation occurred in the 1980’s. Ken Wallace, father of a newborn daughter, realized, after witnessing the local neighborhood pizzeria truck, parked, running and driverless, combined with the surrounding traffic that “Stopping all this for a bit would be most excellent for ...

  • Tidal Power Source

    I imagined some new technique and I want to introduce it. This is only an ideology and not experimented yet. If anybody wants to experiment this i have no objection. According to me any technology that helps the mankind must be universal. I don’t want like anybody’s monopoly on this technology. I wish this technology should be experimented and make this available to generate power, ...

  • A binary ACO for controlling all–electric power take off system in wave energy converters

    This paper describes a metaheuristic algorithm for controlling all–electric power take off (PTO) system of wave energy converters. It provides optimal parameter values to the controller following the instantaneously changing sea state. The output of the algorithm is used to tune the electrical control systems in the PTO system in order to provide sufficient time for the point absorber to achieve ...

  • Is marine energy about to go mainstream?

    Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast.  So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of ...

  • Why it`s time to get serious about wave power

    For most of us power from the sea means watching waves crashing on a beach or smashing up against a breakwater. But if you want to experience wave power at its most energetic then you need to be offshore. In fact you need to be over one hundred kilometres offshore. In February 2000, a British oceanographic research vessel sailing in the Rockall Trough, some 180Km from land, encountered the ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...
