Recycled Tube energy to power stations
London Underground (LU) has been trialling energy capture technology on the Victoria line that could reduce its energy bill by five per cent, saving the organisation millions of pounds.
In what LU claims is a world-first, an inverter system was installed at the Cloudesley Road substation for a five-week trial. According to LU, the reclaimed waste energy from Tube train brakes over a one-week period was enough to power Holborn station for two days. The technology has the potential to capture 1 Megawatt hour (MWh) per day – enough to power over 100 homes for a year.
“This…regenerative braking system has the potential to transform how we power stations across the TfL network, unlocking massive power savings and significantly reducing our energy bills,” said Chris Tong, LU’s head of Power and Cooling.
“We are committed to doing more to reduce our energy use, and this technology - a world first for metro railways - is one of a number of innovations we’re embracing to lower our environmental impact.”
