Energy produced from one of the Northern Line tubes will be used to provide local homes, offices, and leisure centers with heat - using a heat pump to capture excess heat from the tube's ventilator shaft.
'Reduce carbon emissions'
Dubbed as Bunhill 2, the initiative, which is set to commence operations later on in the year, is part of Islington Council's aims to 'make the area more self-sufficient in energy, reduce carbon emissions and lower heating bills for residents'.
According to travel guide Lonely Planet, Lucy Padfield, Director of district heating at Ramboll, said: "We believe that the use of large-scale heat in this way connected to urban district heating systems will play a major part in decarbonizing the UK's heating energy demand."
Earlier this year, the transport network rejected a 'junk food' advert showing bacon, eggs, and butter - as part of a 'groundbreaking measure to help tackle child obesity in London'.
"Food and drink brands, restaurants, takeaways and delivery services will only be able to place adverts which promote their healthier products, rather than simply publicizing their brands," said an official statement.
"With 30 million journeys made every day on TfL’s network, its advertising sites offer a key opportunity to promote good food and a healthy lifestyle to both children and their family members or carers."
