Transport for London today revealed that they plan to make the London Underground more efficient, to do this they will harvest wasted braking energy from the trains that run on the Victoria line.
This captured energy will then by used to power parts of the Underground, TFL says that it could be enough to power the entire Holborn station for more than two days a week.
Matthew Pencharz, deputy mayor for environment and energy, explained:
“The results of this project are really exciting and show huge potential for harnessing some of the immense energy in our Tube trains. The trial puts London at the cutting edge of this kind of technology and clearly demonstrates how energy from trains can be recovered to power Tube stations, making the network more environmentally friendly and cost effective.”
An inverter system has already been tested on the Underground for five weeks, after which TFL seen results that could save them as much as £6 million a year, which comes alongside the added advantage of reducing their carbon footprint.
The system will also mean that less heat will be produced from the brakes of the trains, which means cooler stations and less money spent on cooling them, this all means that TFL could save up to 1MWh per day, which is enough to power 104 average homes a year.
This is all part of London’s Mayor Boris Johnson’s plan to make the Underground greener.
Greenwich Power Station will also be remodelled to covert it into a low-carbon power generator to power the Underground, it will use six gas engines to replace boilers, with wasted heat channeled into a new local heat network for nearby residents.
