  • An Update on Large Scale Wave Energy Conversion
    AN UPDATE ON LARGE SCALE WAVE ENERGY CONVERSION Rik van Hemmen, Fellow and Michael Raftery Member Martin Ottaway van Hemmen & Dolan, Inc. [email protected] [email protected] SNAME – SMC 2019 Technical Paper – Peer Reviewed Abstract Submission SNAME FACE: Engineers/Designers Topic: Design and Engineering, Sustainable Energy It is time for Wave Energy Conversion (WEC) to be part of the sustainable energy toolbox at a utility level. Solar and wind renewable power systems are now sustainable technologies which are economically competitive with existing fossil fuel and nuclear options. Even though there have been WEC development efforts as long as there have been industrial solar and wind efforts, WEC systems simply have never made it out of the experimental starting blocks. This paper examines prior efforts and examines why they have failed at a utility level and describes the design and engineering of emerging technologies that could make large scale wave energy conversion competitive with present state of the art large scale wind and solar projects. The SurfWEC concept is introduced as a game changing approach to achieve much lower Levelized Cost of Electricity (LCOE) rates than are achievable with existing WEC approaches by enabling significant increases in kinetic energy input to various WEC designs.

  • Harnessing Energy from the Oceans
    Harnessing Energy from the Oceans Forever moving - our restless oceans have enough energy to power the world. As long as the Earth turns and the moon keeps its appointed cycle, the oceans will absorb and dissipate vast amounts of kinetic energy - a renewable energy resource of enormous potential. But harnessing this resource has proven more difficult than first thought. In this the latest installment of the GLOBE-Net Series on Renewable Energy - we look at how the power of the oceans might eventually find its place among other forms of renewable energy. Ocean Energy - What is it? According to the United Nations, 44% of the world's population lives within 150 km of an ocean coast. In Canada and Australia the number is much higher at 80%. In the United States 53% of the population lives in close proximity to an ocean. Thus it is only natural that many countries look to the oceans as a source of energy to be harnessed. How they seek to exploit this resource varies according to factors of geography and available technologies. The two main forms of energy associated with our oceans are tidal power and wave power - born of the same source, but different in how they turn energy into electricity. Tidal Power Tidal power coverts the energy of tides into electricity utilizing the rise and fall of the ocean tides. The stronger the tide, either in water level height or tidal current velocities, the greater the potential for tidal electricity generation. Tidal generators act in much the same way as do wind turbines, however the higher density of water (832 times that of air) means that a single generator can provide significant power at velocities much lower than those associated`with the wind power generators.
