On 21st September 2021, one of Europe’s leading energy and heat suppliers, Vattenfall launched their ambitious plan to decarbonise London’s buildings. The planned heat network will be installed in phases as additional homes and low and zero-carbon heat sources join the network, which will serve 75,000 homes by the 2030s. By the 2040s Vattenfall believes the network could be expanded to cover a thirty-mile radius and serve heat to the equivalent of more than half a million homes across east London1. Heating is responsible for a third of UK greenhouse gas emissions and over 25 million homes are still using fossil fuels to keep warm. Modelling suggests Vattenfall’s heat network, which would be the largest in the UK, could reduce emissions by up to 90% in comparison to individual gas boilers fitted in every home4. Over a 20 Year period, a heat network serving the equivalent of 500,000 homes could save 26 million tonnes of CO2 emissions.The catalyst for the project was funding support through the Government’s Heat Networks Investment Project, awarded to Cory earlier this year. Construction for this first phase is set to start in early 2022 and will extract heat from Cory’s Energy from Waste Facility at Belvedere, supplying the first homes by 2024. A second EfW facility, adjacent to the existing one and part of Cory’s Riverside Energy Park which received planning permission from the Government in April 2020, will supply an additional 10,500 homes by the next decade.
