→  Potential savings of 188 ktCO2 over 40 years

→  Six studied locations could provide low carbon heat to up to 15,000 homes

→  40+ stakeholder groups engaged throughout the project

TfL have been exploring how to capture and reuse heat from the London Underground. This project ranked 55 sites against criteria like space, access, constructability and proximity to potential heat users. We selected the best six locations to study in detail, which could heat 15,000 homes and save over 180 kilo-tonnes of CO2 over 40 years. To maintain passenger comfort, ventilation systems operate continuously to reject heat from the tube network. Conversely, buildings at ground level burn fossil fuels to maintain comfort for occupants. By repurposing the wasted heat, buildings can avoid the combustion of gas, delivering significant carbon savings and improving air quality for Londoners.
