Vattenfall Wärme Berlin AG and Siemens Energy signed an agreement today to demonstrate and trial a new large-scale, high-temperature heat pump in Berlin. In the Qwark³ project (the German acronym represents “coupling of district heating, power, and cooling”), they will test the use of this new technology for the first time at Berlin’s Potsdamer Platz to generate green district heating using waste heat and electricity from renewables, and feed it into Berlin’s district heating network. The project is funded by the German Ministry of Economic Affairs and Energy as part of its 7 th Energy Research Program: The aim of the pilot project is to establish robust claims regarding the technical and economic potential of generating heat using large-scale and high-temperature heat pumps.

As a traditional Berlin company, Vattenfall Wärme Berlin AG has been supplying the capital with energy for over one hundred years. Today, 1.3 million residential units in Berlin benefit from locally generated, reliable and environmentally friendly district heating as well as district cooling. Vattenfall Wärme relies on a smartly controlled district heating system, holistically conceived energy concepts and decentralised solutions. The aim for the capital is to become climate-neutral by 2050. Vattenfall supports the state of Berlin in achieving this goal. In a joint climate protection agreement, the company has committed to halving its CO2 emissions by 2020. This goal was already achieved ahead of schedule in 2017. Now, together with the state of Berlin, they are working on the coal phase-out by 2030. In parallel, Vattenfall is working on numerous innovative solutions for its great mission: a life without fossil fuels within one generation.
