New models for London's energy networks

Transport for London is looking at new models of public-private partnership in the area of 'waste heat' and part-funding a PhD with London Southbank University to expand research. Alex Gilbert, at Transport for London, has been talking to Future Cities Forum about this important area of innovation in the capital.

'We have done a huge amount of work to identify all the waste heat across our transport network with live dynamic mapping. We have identified the top few sites from 150 for waste heat, but these need further study to fully understand condition and temperature, in order to answer the question 'what is the asset and what have we got? We have 500 gigawatt hours of waste heat but the challenge is how to get it to homes.'

The work has followed the building of the Bunhill 2 District Heating Network, utilising a London Underground ventilation shaft at City Road abandoned tube station. Islington Council commissioned Ramboll to deliver the network, with the aim of providing cheaper and greener heat to 1,350 homes plus community buildings in north London. Ramboll believes that the heating network is one of the most innovative in the UK, designed to recycle waste heat from the London Undergr
