A west London project will use waste heat from a data centre to supply low-carbon heating to 4,000 homes and a new commercial districtWith millennia of history, hundreds of miles of underground rail and thousands of miles of sewers and pipelines, making large-scale sustainable infrastructural changes in central London is incredibly complex. A redevelopment project in west London is nevertheless set to use waste heat from a data centre in an ambient loop network to supply low-carbon heating to 4,000 homes and a new commercial district. The network will circulate low-temperature water through underground pipes to capture heat from the Mopac Tower data centre, nearby Tube tunnels and other local sources. Building-level heat pumps then raise it to usable temperatures for heating and hot water. Countries including Sweden and Denmark have deployed district heating far more widely, helped by planning systems more supportive of shared energy infrastructure and by historically higher heating costs that drove innovation.
