Lowering carbon footprint with integrated heat pump solutions


♦ Mitsubishi Power Europe powers the market with integrated heat pump solutions for district heating with greater flexibility and security of supply.

♦ The Company, together with partners, will develop the first large-scale heat pump to date in Germany.  

Duisburg, October 14, 2021 – Mitsubishi Power Europe and Johnson Controls, the global leader for smart, healthy and sustainable buildings, have joined forces to develop an integrated heat pump solution for a power plant conversion in Stuttgart-Münster, Germany, operated by EnBW Energie Baden-Württemberg AG. The two companies will be working closely together, combining the heat pump manufacturing expertise of Johnson Controls and the technological know-how of Mitsubishi Power Europe. 

The order will be realized as part of a fuel switch project in which the previous district heating generation with coal-fired steam boilers is to be replaced by more environmentally friendly generation capacities. With a thermal output of approx. 20 MW, Mitsubishi Power Europe will establish the first major heat pump in Germany, enabling EnBW to reduce its carbon footprint significantly. It is expected that approximately 15,000 tons of CO2 can be saved per year utilizing this solution. The pilot plant will for the first time, extract heat from cooling water that was previously discharged unused into the Neckar River. The plant thus sets new standards for the use of waste heat for the decarbonization of district heating.

“Heat pumps are essential in the energy transformation. We are proud to be the key provider in the business to offer integrated heat pump solutions for any industrial application, ensuring the highest reliability, efficiency and smart systems for our clients and partners”, says Andreas Rupp, Head of Sales Business Unit Service at Mitsubishi Power Europe. 

Rainer Schild, Johnson Controls General Manager in Germany, adds, “Large heat pumps in this high output segment are still an exception in Europe, and we are extremely pleased to have Mitsubishi Power Europe on our side in this one-of-a-kind project. This collaboration will help achieve incredible energy efficiency results and pave the way to a sustainable, net-zero future.”

“Becoming climate neutral is our ultimate goal. It is a particular challenge to decarbonize not only the electricity market but also the heat supply. We are pleased to contribute to this goal with the heat pump project in Stuttgart”, says Marc Jüdes, head of the district heating department at EnBW.

This is already the third heat pump order Mitsubishi Power Europe received in less than two years and marks a further step in expanding its product portfolio towards the new market requirements.
