Comments Off on First floating wind farm in the world begins generating power

Five massive wind turbines floating in the sea near Scotland have started sending energy to the grid. Statoil , a Norwegian power company, has been working on the 30 megawatt Hywind Scotland project for several years, and it’s now up and running. The wind farm can power around 20,000 homes. Hywind Scotland is around 15 miles from Peterhead in Aberdeenshire. As the farm’s wind turbines are floating , they can be placed in waters far deeper than those of conventional offshore wind farms. The Hywind Scotland turbines are in water depths of as much as 129 meters, or 423 feet – offshore wind turbines that are attached to the seabed are typically in depths of up to 50 meters, or 164 feet. Related: The world’s largest floating wind farm is planned for the California coast That figure is important because according to Statoil, 80 percent of potential offshore wind locations have water depths greater than 60 meters. And they think their floating turbines could work in even deeper waters than those of Hywind Scotland. Statoil New Energy Solutions executive vice president Irene Rummelhoff said in a statement, “Hywind can be used for water depths up to 800 meters, thus opening up areas that so far have been inaccessible for offshore wind. The learnings from Hywind Scotland will pave the way for new global market opportunities for floating offshore wind energy .” From blade tip to the surface of the sea, the wind turbines are 175 meters, or around 574 feet, large. Scotland’s First Minister Nicola Sturgeon said the project puts the country “at the forefront of this global race and positions Scotland as a world center for energy innovation.” Statoil and project partner Masdar are also working on an one megawatt-hour (MWh) battery storage project, called Batwind, that will store clean power generated from Hywind Scotland. Rummelhoff said Statoil plans to keep working on lowering costs of power from the wind farm, down to €40 to €60 per MWh by 2030.

Spectacular origami pavilion made of recycled plastic pops up in Columbus, Indiana

Comments Off on Spectacular origami pavilion made of recycled plastic pops up in Columbus, Indiana

This gorgeous origami-inspired building in Columbus, Indiana is made entirely from recycled plastic – and it lights up at night with a beautiful LED display. Students at the IU School of Art, Architecture + Design in Bloomington , led by Professor Jiangmei Wu , designed the Synergia pavilion as an experiment in building complex structures inspired by biological forms, soap bubbles, and crystal patterns. The temporary pavilion sits on the site of Eero Saarinen’s North Christian Church in Columbus, and it references the famous architect’s mid-century modernist architecture. Its design stems from a single element– a bisymmetric polyhedron tessellated into interlocking layers. Over 500 polyhedrons, measuring about two to three feet each, work together to form the elongated hexagonal shape.

The plastic corrugated boards are extremely lightweight and can be easily bent along the flutes. When connected together, the folded hinges produce an interlocking self-supporting lattice that is light and yet structurally efficient. This eliminates the need for additional framing and assemblage and reduces waste. + IU School of Art, Architectuare + Design Photos by Tony Vasquez

Offshore wind power is cheaper than new nuclear power in the UK

Comments Off on Offshore wind power is cheaper than new nuclear power in the UK

Offshore wind power has pulled ahead of nuclear power in the United Kingdom . Energy from offshore wind farms will be less expensive than power from a new nuclear project for the first time, based on subsidy figures via the Department of Business, Energy, and Industrial Strategy after an auction. Emma Pinchbeck of Renewable UK said the figures were “truly astonishing.” Two firms said they’d construct offshore wind farms for a subsidy of £57.50, around $76, per megawatt-hour for 2022-23, according to the BBC, which noted these figures are around half the subsidy costs in a 2015 auction. Compare £57.50 with the subsidy secured by new nuclear plant Hinkley Point C , which is £92.50, or around $122, per megawatt-hour. Related: Is this $26 billion UK nuclear power plant worth its ludicrous cost? Pinchbeck told the BBC, “We still think nuclear can be part of the mix – but our industry has shown how to drive costs down, and now they need to do the same.” The BBC listed larger turbines , foundations that cost less, and higher voltage cables as components that have helped reduce prices for offshore wind, along with UK supply chain growth and the oil and gas industry downturn. An example of those larger turbines are new eight-megawatt ones that are nearly 656 feet tall – and Pinchbeck suggested turbines could double in size during the 2020’s. The nuclear industry said nuclear power is still necessary for times when the wind isn’t blowing. Nuclear Industry Association chief executive Tom Greatrex said, “It doesn’t matter how low the price of offshore wind is. On last year’s figures it only produced electricity for 36 percent of the time.” The subsidies for the wind farms will come from a consumer bill levy, and will run for 15 years, according to the BBC. Hinkley Point C’s subsidies will run for 35 years. Minister for Energy and Industry Richard Harrington said the offshore wind projects would create thousands of new jobs .

Comments Off on The world’s largest floating wind farm will be operational next year

Norwegian company Statoil is building the world’s largest offshore floating wind farm near Scotland – and it’s set to start producing energy as early as 2017. The Hywind Scotland Pilot Park wind farm will feature five turbines generating six megawatts of power each.
