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.
