Wind turbine

Swedish company SeaTwirl says its floating vertical-axis wind turbines have what it takes to dramatically reduce the cost of deep offshore wind energy, and it's signed a deal with Westcon to build and deploy a commercial-scale 1-MW turbine in Norway.

Boston startup T-Omega Wind says it's prototyped and tested a unique floating offshore wind turbine that can withstand massive storms, but at 20% the weight and around 30% the price of conventional designs, unlocking the world's best wind resources.

We interviewed the core team at Norway's World Wide Wind to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and density to radically lower the cost of offshore wind.

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today's biggest turbines.

We've seen some inventive ideas around how giant turbine blades might be saved from landfill at the end of their lives, and scientists have just thrown another one into the mix with some wide-ranging, and delicious, potential.

Siemens Gamesa has developed a fully recyclable blade that can be used to create new products when its wind-catching days are done, and it's just been installed on a turbine at a commercial wind farm in the North Sea.

Through its massive wind turbines and innovative offshore designs, GE continues sharpening its toolkit in a bid to built the future of sustainable energy, and a newly unveiled turbine blade shows how that can extend to the materials used.

NYC-based designer Joe Doucet doesn't see why renewable energy generation shouldn't actively make a home more beautiful, so he's putting together a series of "kinetic walls" using rotary wind turbines to achieve some hypnotic visual effects.

Fossil fuel tankers that transport oil, gas and coal across the seas play an important part in the global energy mix, but one Japanese startup is eyeing a future where these types of vessels carry a much cleaner load – energy from offshore wind farms.

More than three years after revealing plans to build a monster offshore wind turbine called the Haliade-X, GE Renewable Energy has announced that the prototype of the latest member of the family has started operating at 14 MW in Rotterdam.

To maximize the exposure of wind turbines, blades are placed atop tall towers on the crests of hills or miles off shore. But a new study has shown how turbines behind hills could actually produce higher amounts of energy than those out in the open.

Norway's Wind Catching Systems has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world's biggest single turbines – while reducing costs to be immediately competitive.
