  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • The wave of the future?

    Green technology may be hot right now, but as Joe Sieber, Sc’64, can tell you, it takes some green—in the form of cold, hard cash—to bring to market even the best green energy idea. Joe has invented a way to extract energy from the waves found on any large body of water—oceans, seas, or lakes. His patented technology is simple, reliable, efficient, renewable, low-cost, and ...


  • Ocean Power connects wave energy system to grid

    Ocean Power Technologies, Inc. (Pennington, NJ) announced that it has achieved what it claims to be the first-ever connection of a wave-energy system to the power grid in the United States. Ocean Power’s PB40 Powerbuoy system is now delivering power to the grid at the U.S. Marine Corps Base Hawaii on the island of Oahu. The Powerbuoy unit, which was installed in December 2009 at a ...

  • 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 ...

  • Description of the Wave Rocker - Technical version -

    Untitled Document Most people think about the sea and waves as something that moves up and down and something that rushes in and out. These observations are correct, but there are many other facts ...


  • 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 ...

  • Power quality improvements employing multipulse full-wave AC-DC converters

    In this paper, a set of full-wave AC-DC converters are investigated for power quality improvement in AC mains and DC output. A detailed classification of these full-wave AC-DC converter configurations is made in different transformer connections and several new configurations of isolated and non-isolated full-wave AC-DC converters are developed to meet specific application requirements. The ...

  • Microwave UV: A New Wave of Tertiary Disinfection

    Currently UV disinfection technologies available for use in drinking water and water reuse applications typically utilize one of three types of mercury UV lamps. These three types of mercury UV lamps include low pressure, low-pressure high-output, and medium-pressure lamps. All of these lamps contain electrodes that facilitate in the generation of UV radiation. These electrodes are of delicate ...

  • Wave of CSP activity across the MENA region

    Looking beyond Saudi Arabia, the CSP Today Global Tracker highlighted a number of updates made this week that demonstrate the progression of the concentrated solar power industry in MENA. While attention has focused heavily on the Saudi Arabian solar opportunity, it should not be forgotten that there are a number of pipelines now opening for CSP companies in the Middle East.  The ...

  • 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 ...

  • Study on hydrodynamics and heat transfer of solitary wave on film flow with CFD method

    In this paper, a capacitance probe and high speed camera are adopted to study the solitary wave of falling film on large flat plate experimentally. Two types of solitary wave are studied with a Computational Fluid Dynamic (CFD) method based on the measuring data. The water–air shear stress on the interface of the solitary wave is modelled in the numerical calculation. The results indicate that ...

  • WorldWaves wave energy resource assessments from the deep ocean to the coast

    Abstract WorldWaves is a global wave and wind climate package developed through EU and industry sponsorship over many years. The offshore data incorporates global hindcast and operational wave and wind data from ECMWF, validated and calibrated with independent satellite and buoy data worldwide. These data, which may comprise full directional wave spectra time series, are used as ...

  • ‘Placard-waving cranks’ derail Able UK’s ship recycling bid

    Able UK, the company at the centre of the so-called ‘US ghost ships’ saga, has been refused permission to extend the use of its site in north-east England to encompass ship recycling. Widespread exasperation has greeted the news, with one supporter of the scheme claiming that the views of ‘placard-waving cranks’ have been allowed to scupper plans for an environmentally important facility. The ...

  • National Grid Alert Triggers Wave of Enquiries for Renewables Sector

    UrbanWind today reported a sharp increase in companies enquiring about on-site power generation, following National Grid’s warning yesterday.   It said growing numbers of British businesses were now looking to move towards ‘energy independence’ to protect themselves from the rising threat of future brownouts. ...


  • Supporting wave and tidal energy in the UK - an analysis of UK Policy 2000-2009

    In order to stimulate UK based marine energy technology developers, the UK Government launched the Marine Renewables Proving Fund (MRPF) in 2009. This instrument was designed to bridge the gap between early-stage research funding and the recently-criticised Marine Renewables Deployment Fund (MRDF). This paper develops an analysis framework for policy instruments designed to support technology ...

  • Dynamic rotary torque measurement using surface acoustic waves

    The subject of torque measurement has previously been addressed extensively. Most of the existing transducers either rely on low voltage analogue systems (e.g. conventional resistive strain gauge) or complicated mechanical assemblies by physically assessing displacement, i.e. optical systems. This paper identifies a new, potentially low cost, non-contact, frequency domain strain torque sensor1 ...

  • A predictive algorithm for minimising dead–time distortions in sine–wave VSI with L–C output filter

    In many applications, single–phase sine–wave inverters are operated with low–pass filters at the output to deliver a low–distortion sinusoidal voltage to the load. In such cases, it is essential that the output be as close to a sinusoid as possible. However, conventional bridge–type inverters, which must be operated with some dead time, suffer from dead–time distortion problems. This effect ...
