Six promising marine energy technologies will share 22 million pounds ($35.04 million) of UK government funding to speed up deployment of full scale prototypes, the Carbon Trust said on Tuesday.
a 1,320-megawatt tidal power plant will be built on a 157.45-square-kilometer area of sea near the islands of Ganghwa, Jangbong and Yeongjong. The government will build it by 2017 at a cost of 3.92 trillion won ($3.0 billion), the report said.
World Energy Research and Blue Energy Canada have signed an agreement to develop a 200 MW commercial tidal power project, Renewable Energy World reports. The cost is $500 million; the location isn't entirely clear. The technology? Blue Energy's vertical axis tidal turbine
New York City has installed a new-and-improved aluminum alloy turbine in the East River, the only of its kind in the United States.
The turbine is the first of 300 which the city hopes to install in the waterway. Unlike the typical river which flows in a constant direction, the East River is a tidal straight with strong, fluctuating currents which allow for more efficient power generation. Once in place, the system could provide electricity to 10,000 households.
Oxford researchers have developed a new tidal turbine which has the potential to harness tidal energy more efficiently and cheaply, using a device which is simpler and more robust and scaleable than current designs.
They have designed, built and tested the device, a horizontal axis water turbine, to intersect the largest possible area of current. The rotor is cylindrical and rolls around its axis, catching the current.
A tidal-power system has been connected to the National Grid in Northern Ireland. Built by the British tidal-energy company Marine Current Technologies (MCT), the 1.2-megawatt system consists of two submerged turbines that are harvesting energy from Strangford Lough's tidal currents
