A huge proportion of London’s emissions comes from burning fossil fuels to power and heat buildings. The challenge is how do we supply a city that is continuously growing and has ever-increasing energy demands with cost efficient low carbon energy.
The good news is, there are companies like E.ON that are implementing ways to tackle this problem through district heating networks. In this episode, Imogen and the team went to visit Citigen, a hidden district heating network that provides low carbon heating, power, and cooling to homes and businesses in London’s Square Mile including the Barbican Centre, Museum of London and the Guildhall.
So could this be a blueprint for how cities can transition toward a greener future?
