Bunhill 2 Energy Center
Bunhill 2 Energy Center shows how important city councils are for the energy transition. We met Kenneth Hoffmann, Iain Eckett and Jim Harrison from GEA Heating and Refrigeration Technologies who showed us the installation. The Bunhill Energy Center sits on top of a subway ventilation shaft and uses the energy stored in the air to provide heating to the users of the local district heating system, including a school. The heat leaves the subway at around 20°C and is upgraded to 85°C using the heat pump. The center also houses a CHP unit which makes it a true star for an integrated energy system that can be used for grid stabilization and for maximizing both energy efficiency and renewables use. Islington council aims to repeat the concept in at least 16 locations. We hope other city councils take note, as the concept is working with multiple energy sources. Hence you do not need a subway system to benefit from it.
