Johnson Controls decarbonizes Vattenfall power plant in Berlin

Johnson Controls’ industrial refrigeration business has deployed its proven Sabroe heat pump technology with 700 kW heating capacity at Vattenfall Europe’s Berlin-Buch combined heat and power (CHP) plant Wärme AG in Berlin, Germany. The CHP plant currently uses a waste heat boiler to capture waste heat from an existing gas turbine to generate heat for the local district heating network. The addition of the heat pump will increase the plant’s district heating capacity without burning additional fossil fuel, contributing to energy security and avoiding the production of approximately 620 tonnes/year of carbon dioxide emissions.

In BerlinVattenfall operates the largest district heating network in the Western Europe with approximately 1.3 million connected homes. In total, 2,000 kilometers of pipes supply the connected properties with hot water from 80 to 135°C which supplies heating and hot water to the connected residences. The Buch Islands network north of Berlin provides a total of around 10,000 apartments and 500 individual facilities such as schools or clinics with climate-friendly heat.

“This project puts the power of heat pumps to work to meet energy needs while reducing waste, emissions and costs. Importantly, heat pumps provide the required heating without the need for additional gas supplies,” said David Dorney, vice president and general manager of industrial refrigeration at Johnson Controls. “We are proud to be part of the energy transition here in Germany and this project gives us the opportunity to operate our large heat pumps and provide energy, environmental and safety solutions.”

Germany is in full energy transition, named Energiewendewhich will see an increase in renewables and the reduction of fossil fuels as it aims to achieve carbon neutrality by 2050. The government has said coal-fired power generation will be phased out by 2038. The clean Vattenfall’s CO2 roadmap will see it completely phase out coal in its heat portfolio by 2030 in support of national targets.

“The new heat pump installation in Berlin-Buch is part of our goal to enable fossil-free living within a generation, while meeting our customers’ expectations for affordable electricity and heat supply in the city ​​of Berlin. We are proud to be part of the pioneering effort to deploy heat pumps across germany energy sector,” says Andreas HeuerAsset-Manager dezentrale Anlagen, Vattenfall.

After its commissioning, the plant now complies with its performance guarantees.

Johnson Controls is at the forefront of the technology needed to decarbonize buildings. The company helps meet the growing demand for energy efficient technologies and offers innovative building management solutions such as VAV HVAC systems, as well as its most advanced energy efficient heat pumps. Johnson Controls’ portfolio of services and solutions, powered by OpenBlue, can also lead to significant improvement in energy efficiency and corresponding carbon emissions.

“Reducing carbon emissions from the use of fossil fuels in heating/cooling, whether for district heating, industrial processes or in buildings, must be a top priority if we are to achieve a net saving zero in the fight against climate change,” mentioned Katie McGinty, vice president and director of sustainability and external relations at Johnson Controls. “Heat pumps are essential because they reduce natural gas requirements and increase energy security while allowing us to absorb almost 40% of global CO2 emissions from buildings. Natural gas is the main source of energy for building heating, we are eagerly scaling up our production of heat pumps and other solutions to meet the challenge of improving building efficiency and a net-zero and secure energy future.”

Both Vattenfall and Johnson Controls are founding members of the First Movers Coalition. The coalition was launched at COP26 in Glasgow by the US State Department and the World Economic Forum. Coalition members are committed to increasing the share of emerging technologies critical to the transition to net zero. As a leader in buildings for more than 135 years, Johnson Controls has been a pioneer in sustainability. Among the first industrial companies to report their emissions and commit to reducing their emissions, the company has made tremendous progress in reducing carbon emissions and energy intensity by more than 70% since 2002. one of the World’s 100 Most Sustainable Companies by Corporate Knights — number one in its industry sector.
