Summary

Johnson Controls (NYSE: JCI), the global leader in smart, healthy and sustainable buildings, today announced a new agreement to help the city of Hamburg, Germany, decarbonize its district heating network. As part of a collaborative project between HAMBURG WASSER (Hamburg Water) and Hamburg Energiewerke (Hamburg Energy), Johnson Controls will equip the Dradenau site of Hamburg's central wastewater treatment plant with a new heat pump system that will save around 66,000 tons of CO2 annually. Detailed engineering is underway and the plant is expected to supply the city with fossil-free heat using the new heat pumps from 2025.

Under the terms of the deal, Johnson Controls will install four large-scale, 15 MW heat pumps that will supply environmentally friendly heat to more than 39,000 residential units. Instead of using fossil-based heating, the heat pumps will extract heat from treated wastewater that leaves the plant each day and feed it into the central district heating system of Hamburg Energie, part of the Energiepark Hafen (the city's Port Energy Park) heating network. The project is among the first large-scale heat pump projects in Germany.
