10 August 2016: Welcome to see the Evening Standard today include a major comment piece by Leo Johnson on how “Small-scale projects such as those in Newham, Brixton and Islington give a glimpse of Britain’s energy future”.
Leo highlights three projects in London as signs of how the decentralised energy model is now in the ascendancy, shifting from the “dominant energy model, the centralised production and distribution of fossil fuel-based power through the grid”.
- “In Newham, for example, the Combined Heat and intelligent Power plant (CHiP) aims to harness the energy from “fatbergs”, the bus-size balls of grease which cost Thames Water an estimated £1 million a month to remove, using teams of trained “flushers” decked out with protective white suits and shovels who descend into London’s Victorian sewer system to hack up the fat. CHiP plans to use the fat instead to power 40,000 homes.” This project is fascinating and received a lot of coverage when first announced back in 2013 – which was covered in some detail in an earlier post here – but not much further information has been forthcoming from the project on their website.
- “In Brixton, the energy group Repowering is installing solar panels on the rooftops of housing association buildings to lower fuel bills, and is teaming up with Transport for London to introduce “energy gardens” across 50 London Overground sites.” In June of this year, Repowering was awarded a prestigious Ashden Award for their work – a case study and excellent video are posted on the Ashden website here. The Energy Gardens project was covered by ITV news a few weeks ago – see video here – and more can be seen at energygarden.org.uk
- “At the Bunhill Energy Centre project in Islington, whose second phase was opened by Mayor Sadiq Khan last month, they’re using heat from the Northern line tube to power a thousand homes.” Lots more about Bunhill here.
Leo also highlights some work commissioned by the GLA by engineers Buro Happold “have estimated that there is enough heat wasted in London alone to power 70 per cent of the city’s energy needs. What’s the potential for growth? Copenhagen provides 98 per cent of its space and water heating through district heating, at 45 per cent of the cost of normal oil heating bills. London’s uptake, better than the one to two per cent national average, is currently just five per cent.” The 2013 London Secondary Heat study can be downloaded here.
