World’s first floating wind farm to be built off Scottish coast

In a deal between the Scottish government and Norwegian oil company Statoil, five wind turbines with a capacity of six megawatts each will be set on floating structures some 15 miles (25 km) off the northeast coast of Scotland near Peterhead. The Hywind pilot park, as it's named, is claimed to be the first floating wind farm in the world, and will generate enough power for 20,000 homes with operations expected to start in late 2017.Read More

The U.S. dips a toe in the offshore windfarm water

Offshore wind farms have been creating electricity off the coast of Denmark since 1991 and England, Germany and other countries on mainland Europe have followed suit, as have China, South Korea and Japan. It's a different story in the US, where until recently there were no offshore wind farms in operation or even under construction. That changed recently with the start of construction of a small wind farm off the coast of Rhode Island.Read More

Seatower's game-changing wind turbine foundations could reduce the cost of offshore wind farming

Offshore wind farming combines the clean, green, environmentally neutral benefits of land-based wind turbines, while being a lot less visually intrusive ... and restricting the usual NIMBY opposition to crustaceans and invertebrates. It's currently a lot more expensive to install turbines out at sea, though, and that's restricting the sector's development. Which is why the Seatower Cranefree turbine platform could be such a significant step forward. Cheaper and easier to install, and requiring less gargantuan and specialized equipment than standard monopile foundations, the Seatower base could help offshore wind farms reach profitability a lot quicker.Read More

Europe joins race to store energy at the bottom of the ocean

"Imagine opening a hatch in a submarine under water. The water will flow into the submarine with enormous force. It is precisely this energy potential we want to utilize." This is how German engineer Rainer Schramm describes his idea for storing energy under the sea. By using surplus energy to pump water out of a tank at the seabed, the water is simply let back in again when there's an energy shortfall, driving turbines as it rushes in. The deeper the tank, the more power is generated.Read More

Concrete spheres could deliver feasible energy storage for offshore wind turbines

The intermittent nature of wind and solar power generation is one of the biggest challenges facing these renewable energy sources. But this isn’t likely to remain a problem for much longer with everything from flywheels to liquid air systems being developed to provide a cheaper form of energy storage than batteries for times when the wind is blowing or the sun isn’t shining. A new concept out of MIT can now be added to the the list of potential solutions. Aimed specifically at offshore wind turbines, the concept would see energy stored in huge concrete spheres that would sit on the seafloor and also function as anchors for the turbines.Read More

World's largest wind farm, London Array, brought fully online

Phase one of the London Array usurped the UK's Greater Gabbard to become the largest operational offshore wind farm in the world when its final turbine (its 175th) was commissioned on Saturday afternoon. Though construction was completed back in December, it is only now that all of the farm's turbines are supplying the UK's national grid with electrical power. The array has a total capacity of 630 MW.Read More

Japanese bank to fund first U.S. offshore wind farm

Not having a section devoted to cures for insomnia, Gizmag tends to pass over press releases about investment agreements. Tuesday's announcement that the Bank of Tokyo-Mitsubishi UFJ (BTMU) is to find somewhere in the order of US$ 2 billion for the Cape Wind is extremely interesting, however, as it means the U.S. should finally build its first offshore wind farm, with construction slated to commence before the year's end.Read More
