• Joint trial of a large-scale, high-temperature heat pump in district heating network
  • Waste heat and renewable electricity utilized to achieve heating transition in Berlin
  • Federal government-funded project links heat, cooling, and electricity

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 7th 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.

Since 1997, the cooling plant on Berlin’s Potsdamer Platz has been reliably supplying locally and efficiently generated cooling power to some 12,000 offices, 1,000 housing units, and (...)
