I n B r i e f Western Australian company, Carnegie Corporation, is proposing to set up the world’s first base-load wavepower electricity station and desalination plant by 2012 based on locally developed CETO technology. Carnegie Managing Director Dr Michael Ottaviano says the company is finalising details for a $400 million 50 megawatt (MW) demonstration wave farm that could supply power for around 40 000 households. He says that once it was up and running, the wave farm’s operating cost ‘should be competitive with fossil fuel alternatives as it has zero fuel costs’. CETO – named after the sea goddess of Greek mythology – comprises an array of subsurface buoys connected to pumps on the seafloor; the movement of buoys in response to wave pressure variations drives the pumps. Pressuredriven water is then piped to a land-based hydroelectric turbine or reverse-osmosis desalination plant, or both. According to the Carnegie Corporation, any combination of power and water is feasible, fr

O’Reilly and Ömer Savaş Department of Mechanical Engineering, University of California at Berkeley Carolyn Q. Judge Department of Naval Architecture and Ocean Engineering, United States Naval Academy N. Sri Namachchivaya Department of Aerospace Engineering, University of Illinois at Urbana Champaign Abstract: This research proposal is concerned with the design and analysis of an ocean wave energy converter (WEC) which uses a novel water intake system to vary the mass of the converter. With the help of a simple model for a hybrid system, the variation of mass is shown to increase the energy harvesting capabilities of the converter. The present paper presents a summary of the analysis of the hybrid system along with preliminary experimental results. 1. Introduction: Ocean waves contain the highest energ

Wave Powered Desalination. Stephen H Salter*, Joao MBP Cruz, Jorge AA Lucas, Remy CR Pascal. Institute of Energy Systems, School of Engineering and Electronics, University of Edinburgh. Mayfield Road, Edinburgh, EH93JL, Scotland. S. Salter@ed. ac. uk, tel +44 131 650 5704 fax +44 131 650 5702. ABSTRACT The electrical energy needed to drive desalination plant can be produced from renewable energy sources if their erratic outputs can be made to match the strict specifications of an electrical network. However energy from sea waves can also be used directly, using the vapourcompression desalination process. This inherently provides the correct impedance match to wave inputs and does not suffer from wild swings of power level. This paper extends one given to the 2005 World Renewable Energy Conference, (Salter, 2005) by the inclusion of numerical predictions and proposals for a mooring design.

A First course in Renewable Energy IAP 2009 Massachusetts Institute of Technology Instructor Mohammad-Reza Alam (PhD) Course Description This is an engineering introduction to renewable energy technologies and potentials. The course aims to introduce a general engineering/science audience to the basic concepts of renewable energy. In the interest of time some mathematical criteria will be covered, e. g. Betz limit for wind, limit of efficiency of WEC point absorber. Each lecture contains several examples from real world applications and in-progress industrial developments. Lectures Tuesdays and Thursdays 11:00am-12:30am Textbook Godfrey Boyle, “ Renewable Energy, Power for a sustainable future”, 2004, Oxford University Press, in association with The Open University.

However, the energy required to run desalination plants remains a drawback. The idea of using renewable energy sources is fundamentally attractive and many studies have been done in this area, mostly relating to solar or wind energy. In contrast, this study focuses on the potential to link ocean-wave energy to desalination. The extent of the resource is assessed, with an emphasis on the scenario of wave energy being massively exploited to supply irrigation in arid regions.
