Wave-powered Desalination

Written by , on May 29, 2010

Independent Natural Resources Inc, has received a permit for a wave powered facility to desalinate water off the coast of Freeport, Texas. The company hopes that the system will be in operation by the end of the year. The facility will be a 25 by 50 metre platform under which there will be 18 of […]  Read more »

Underwater Kites to Tap Tidal Power

Written by , on May 12, 2010

Minesto, a Swedish company which is a spin-off from Saab, has obtained funding to test underwater tidal power kites off the coast of Northern Ireland. The underwater tidal kite consists of a turbine, generator, rudder, which is attached to the bottom with a tether. According to Minesto, it can produce energy in deep water with low […]  Read more »

The world’s largest tidal power station is to be constructed off the west coast of South Korea at Incheon. GS Engineering and Construction has signed a memorandum of understanding with Korea Hydro and Nuclear Power to begin construction next year with a view to completion around 2017. The power station will have a capacity of […]  Read more »

World’s Largest Wave Power Generator Launched

Written by , on November 30, 2009

The world’s largest working wave energy electricity generating device has been officially launched in Scotland. Known as Oyster, the device, built by Aquamarine Power, is stationed at the European Marine Energy Center Billia Croo site near Stromness. At present, it is the world’s only wave energy device which is producing power to the grid. Oyster […]  Read more »

Australia Has Greatest “Blue Energy” Potential

Written by , on October 30, 2009

The term "blue energy" refers to salinity gradient power – the energy retrieved from the difference in the salt concentration between seawater and river water. The power is generated using osmosis with ion-specific membranes. Jan Post, at Wageningen University in the Netherlands, has researched the global potential for electric power generated in this way. His […]  Read more »

New Technique for Power from Salt Water

Written by , on September 3, 2009

Scientists in the Netherlands have previously succeeded in generating electricity at the point where salt and fresh water mix in an estuary using a membrane. Unfortunately, the membranes are expensive and delicate, making the technique costly. Now Doriano Brogioli of the University of Milan Bicocca in Monza, Italy, has published a paper in the Physical […]  Read more »

New Wave Power Technology Demonstrated

Written by , on May 9, 2009

A British company, Checkmate Seaenergy Ltd, has demonstrated a new wave energy device known as “Anaconda”.. Its inventors claim the key to its success lies in its simplicity: Anaconda is little more than a length of rubber tubing filled with water. Waves in the water create bulges which travel along the tubing gathering energy. In […]  Read more »

Wave Power Setback

Written by , on March 18, 2009

 Last July, a Pelamis wave power generator was towed into the Atlantic about 5 kilometres off the coast of Aguçadoura in northern Portugal. In September, two more Pelamis uints were added. Each Pelamis unit was capable of generating about 750 megawatts of electricity – making this the world’s first commercial wave power project. The project […]  Read more »

Google Patents Wave-powered Data Centre

Written by , on January 13, 2009

Google has filed a patent for a wave-powered data centre. The data centre would also use sea water for cooling. There are currently an estimated 44 million servers in use worldwide. These use about 0.5% of the world’s electricity – about the same amount as Argentina or the Netherlands. Google’s patent envisages using existing technology, […]  Read more »

First Commercial Tidal Energy System on Full Power

Written by , on December 19, 2008

A tidal turbine near the mouth of Strangford Lough in Northern Ireland has begun producing electricity at full capacity for the first time. The SeaGen system is generating 1.2MW, the highest level of power produced by a tidal system anywhere in the world, and is claimed to be the first truly commercial ocean tidal system […]  Read more »
