The scheme will capture waste heat from London Underground tunnels and an electrical substation to help warm homes and cut energy bills. The project, the first of its kind, is a partnership between Islington Council, the Mayor of London Boris Johnson, UK Power Networks and Transport for London.
London Underground generates large amounts of heat, which will be captured from nearby Northern Line vent and piped into the heat network which warm local homes.
Councillor Rakhia Ismail, Islington Council’s executive member for sustainability, said the scheme would “boost our work to tackle fuel poverty” and reduce local CO₂ emissions by 500 tonnes a year.
Matthew Pencharz, senior adviser on environment and energy to mayor of London Boris Johnson, said it would help create “a more secure, cost-effective and sustainable heat and power supply for London. We can not only save money but also drive innovation, jobs and growth in this burgeoning sector”.
The mayor wants to reduce CO₂ emissions by 60% and produce 25% of London’s energy from local sources by 2025, and aims to encourage further schemes tapping waste heat. It will be expanded to capture heat from the vent and the sub-station, enabling at least 500 more homes to be connected to the network.
