London’s subway will be supplying green energy to warm up more homes around the borough.

A new project announced by the Islington council will redirect the heat from a Northern Line of London’s subway to vent to homes across the city, giving homeowners a new way to get through the cold season. The project will deliver cheap heating to 500 homes around the area. It will not only be saving consumers money, but also the environment from 500 tons of CO2 emissions.



This is the first known project of its kind. Spearheading a green initiative  to harness secondary heat, Boris Johnson, Mayor of London, believes in making use of “waste heat arising as a byproduct of industrial and commercial activities” and “the heat that exists naturally within the environment (air, ground, water).”

The project is made possible by Islington’s Bunhil Heat and Power network, which has already provided green energy for 700 homes in the borough. The London Underground vent from a Northern Line station will supply most of the heat, but a supplementary supply from an electrical substation owned by UK Power Networks will also be captured.

Martin Wilcox in a statement shared:

If it is successful there could be potential to replicate this and increase access to low carbon, low cost energy in other parts of the capital because we have electricity substations dotted throughout London which keep the lights on for millions of homes and businesses.

With a start-up budget of £2.7m granted by the Islington Council and an additional £1m coming from the EU, the project will be carrying out the promises of the Mayor and meeting his goal to reduce CO2 emissions by 60 percent. If all goes well, this heat-recycling project could account for 25 percent of London’s energy by 2025.

This London project is part of the larger European Union CELSIUS project, which aims to improve the efficiency and performance of district heating systems by capturing waste heat and turning it into useable energy.
