The idea is as ingenious as it is unique and has the potential to become a global role model: the Bunhill Heat and Power Network (BHPN) project in central London. By using waste heat from the London Underground network, 1,350 homes, a school and two leisure centers in Islington are now heated and supplied with hot water as part of the council’s efforts to reduce carbon emissions and achieve CO2 neutrality by 2030.
In partnership with main contractors Colloide Engineering Systems, global technology specialist GEA supplied a purpose built heat pump solution for this flagship project, the first of its kind in the world. Bunhill 2 Energy Centre represents a real blueprint for the use of waste heat from public facilities, taking advantage of state-of-the-art technology on the site of the former City Road London Underground station which was decommissioned almost 100 years ago. The remains of the station have now been converted into a huge underground air extraction system that draws warm air from the tunnels underneath, still used by the London Underground’s Northern Line.
