Summary
District heat networks that use locally available waste heat could be key to delivering on the UK's low carbon energy commitments. Will Stirling reports.
Engineers in the energy distribution and heating industry are working on a daunting but exciting challenge that recently received a government boost.
About half of all energy consumed is used to generate heat and hot water and, to achieve government carbon targets to comply with UK’s Paris Agreement obligations, the carbon intensity of this energy needs to be reduced by 90 per cent by 2050. As vast amounts of waste heat produced by sources from processing plants, data centres and even sewage are going, literally, up the chimney, it’s little surprise that the UK’s energy and heat policy is now focused on capturing this heat to distribute it to consumers, cutting CO2 emissions and lowering the amount of energy required to heat water.
Engineers and heat experts are looking to Europe to adopt a system that redesigns heating and energy into a smart, decarbonised, integrated system – heat networks.
