  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Modelling runoff on ceramic tile roofs using the kinematic wave equations

    Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, by comparing the numerical results with the ones ...

  • EC support for UK power link raises Ireland’s offshore export potential

    The European Commission (EC) announced November 18 it had given priority status to ISLES, a cluster of Irish Sea grid projects which would transmit power from proposed Irish offshore wind farms to the UK grid. There are currently five Irish offshore windfarm projects for a total 2.6 GW of capacity. The inclusion of ISLES in the EC’s list of “projects of common interest” allows ...

  • European Power Markets in Transition

    With European energy markets in transition, all market participants now face a number of potentially tricky challenges. A combination of EU initiatives, increasingly invasive regulations and a backdrop of falling and less volatile commodity prices, have precipitated an era of change and uncertainty in which there are fewer trading opportunities and profits are harder to come by. Analysis ...

  • 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 ...

  • 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 ...

  • “We continue to be stunned at how rapidly the ocean is warming.”

    Oceans have been absorbing more of global warming’s heat and energy than would normally be expected, helping to slow rates of warming on land. But how long will that last? Probing a blue abyss can be an abysmal recipe for the blues. For every 10 joules of energy that our greenhouse gas pollution traps here on Earth, about 9 of them end up in an ocean. ...

  • 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. ...


  • Marine crude oil transport – global voyage losses

    Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice a year. The 2013 autumn meeting was held in Rio de ...

  • 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 ...

  • Analytical solution of a kinematic wave approximation for channel routing

    The kinematic wave approach is often used in hydrological models to describe channel and overland flow. The kinematic wave is suitable for situations where the local and convective acceleration, as well as the pressure term in the dynamic wave model is negligible with respect to the friction and body forces. This is the case when describing runoff processes in the upper parts of catchments, ...

  • The MAGnificent Seven - Gunning for Marine Waste

    Waste Management World focused this article on Terragon Environmental Technologie's product, MAGS (Micro Auto Gasification System) and the solution it provides to the maritime sector.  MAGS transforms solid waste and sludges into energy which can be intergrated at the site where waste is generated.  New regulations from MARPOL Annex V came into effect on January 1, 2013 - virtually ...

  • UK energy – time to face some hard truths

    How can the UK meet its future energy needs? Tom Delay, CEO of the Carbon Trust, looks at how we can solve the problem with our energy future. The future of nuclear power in the UK looks well and truly stuck. The whole episode illustrates how high the stakes are at present for our energy future. Last month the new nuclear plant at Hinckley C was granted planning permission but we ...

  • 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 ...

  • Critical review of energy options

    Short term measure for dealing with energy crisis is reducing consumption by: 1) improving the efficiency of all energy consuming machines; 2) eliminating the wasteful use of energy. Renewable sources of energy such as solar, wind, tidal, waves, etc., do make a significant contribution to demand for energy but they are unlikely to meet the ever increasing consumption. Long term measures may ...
