The flowing waters in the rivers and tidal waves can be a good source of alternative energy. With 70% of the earth's surface covered with water, a great amount of energy can be produced by placing turbines at strategic locations under strong currents. This method of generating electric power is called hydrokinetic power generation. In fact, plans are under way to install 875 submerged turbines inside the Niagara river. 1 Comment
Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.
The development of the first subsea commercial wave farm by a Scottish company took another important step forward today (Tuesday February 20th 2007) with news that Scottish wave energy company, AWS Ocean Energy Ltd. based in Alness, Ross-shire, has secured £2.128 million funding from the Scottish Executive. The funds will be used to develop and commercialise AWS' Archimedes Wave Swing, one of the few proven technologies worldwide for generating clean, renewable electricity from the ocean's waves. The support for AWS is part of a £13 million support package for Scottish marine energy developers funded by the Scottish Executive, which aims to establish Scotland as a world leader in marine energy. 7 Comments
The Ocean Renewable Energy Coalition (OREC) was founded in 2005 by Sean O'Neill (founder of Symmetrix) and Carolyn Elefant (Law Offices of Carolyn Elefant). The mission of OREC is the advancement and commercialization of offshore renewables, including offshore wind, ocean wave, OTEC and ocean and stream based tidal and current (hydrokinetic) technologies. In 2006 OREC lobbied for federal funding for offshore renewable projects and tax incentives to stimulate private investment. 1 Comment
BioPower Systems is developing a new ocean energy technology in Australia that will use bionics to mimic natural systems in order to produce energy. Both bioSTREAM and bioWAVE technologies use biomimicry, which refers to the adaptation of biological traits in engineered systems. BioPower Systems has copied many of the beneficial traits from natural systems in the development of the new ocean energy conversion systems. The company is researching this new technology for application. Laboratory testing will be completed in 2007, and full-scale ocean-based prototypes will be tested in 2008. Commercial units are expected to reach the market by the end of 2009. 1 Comment
A Portuguese energy company called Enersis is funding a commercial wave energy project in Northern Portugal. Construction will begin at the end of October 2006. The project will use Pelamis wave generator technology (manufactured by Ocean Power Delivery) to harness energy from the ocean. After two decades of research and testing at the Lisbon Technical Institute, the first stage of this ocean energy project is intended to produce 2.25 megawatts and power homes through the nation's state-run electrical grid system. Ocean Power Delivery is considered to be the world's leading ocean energy company. No Comments
Mr. Sean O'Neill, President of Ocean Renewable Energy Coalition, on Renewable Ocean Energy: Tides, Currents, and Waves. Ocean Renewable Energy Coalition is a trade association founded to promote energy technologies from clean, renewable ocean resources. The coalition is working with industry leaders, academic scholars, and other interested NGO's to encourage ocean renewable technologies and raise awareness of their vast potential to help secure an affordable, reliable, environmentally friendly energy future. This is text of the Testimony before the Committee on Resources, Subcommittee on Energy and Mineral Resources, Unites States House of Representatives. 3 Comments
