World's largest solar-powered bridge opens in London

After nearly five years in the making, Network Rail has today cut the ribbon on the world's largest solar-powered bridge at Blackfriars Bridge across the River Thames.

As part of a project with solar installation firm Solarcentury, the roof of the bridge has been covered with 4,400 photovoltaic panels, providing up to half of the energy for London Blackfriars station.

First Capital Connect, which runs Blackfriars, expects the panels to cut the stations' carbon emissions by an estimated 511 tonnes a year, further reducing the carbon footprint of its train routes to the south east of England.

"Electric trains are already the greenest form of public transport - this roof gives our passengers an even more sustainable journey," said David Statham, managing director of First Capital Connect. "The distinctive roof has also turned our station into an iconic landmark visible for miles along the River Thames."

The bridge will also act as a major advertisement for London's efforts to become a sustainable city, with tourists and workers viewing the panels as they enter the capital.

7,500 homes are a lot of homes for just one wind turbine.

On Tuesday the world’s largest and most powerful wind turbine swung into gear at the Danish National Test Centre for Large Wind Turbines in Østerild. The prototype V164-8.0 MW wind turbine is 720 feet tall, has 260-foot blades, and can generate 8 megawatts of power — enough to supply electricity for 7,500 average European households or about 3,000 American households.

A joint venture between Vestas and Mitsubishi Heavy Industries, the turbine is slated to go into production next year and was designed to take advantage of the growing offshore wind industry across Europe.

“We have now completed the production, testing, and installation of the V164-8.0 MW as planned, thanks to the team’s intense effort during a time when Vestas has reduced its investments and lowered fixed costs,” Anders Vedel, Chief Technology Officer for Vestas,said. “We now look forward to evaluating the turbine’s performance on site.”

According to the European Offshore Wind Industry, 418 offshore turbines came online last year, providing 1,567 MW of capacity. That brought the total offshore wind capacity in Europe to 6,562 MW with just over 2,000 turbines, enough to provide 0.7 percent of the EU’s electricity. The European Offshore Wind Industry estimates that by 2020 Europe’s offshore grid should have a capacity of 40 gigawatts and by 2030 it should have 150 gigawatts, enough to provide 14 percent of the EU’s electricity demand.

Britain has the most installed offshore wind capacity with 3.68 gigawtts while Denmark is a distant second with 1.27 gigawatts.

Vestas is Europe’s second leading wind turbine manufacturer, after Siemens, a German company. As of last year Vestas had installed 27 percent of Europe’s offshore wind turbines, or 547, compared to Siemens’ 1,249, or 60 percent.
