A new high-temperature heat pump is to generate heat in Berlin in a more climate-friendly way in the future.
Promoting the transition to clean energy in Berlin
The project is funded by the German Federal Ministry of Economics and is intended to drive forward the transition to clean energy in Berlin. According to the companies, the pump saves around 6500 tons of carbon dioxide in the heating system per year, which is equivalent to over 3 million cubic meters of natural gas. According to the report, the system utilizes the surplus waste heat generated in the cooling center at Potsdamer Platz. The heat generated in this way flows directly into Berlin's city heating network. The refrigeration plant produces cold water for cooling businesses and households.
Generating heat from cold
"The banal principle is to generate heat from cold," said Tanja Wielgoß, CEO of Vattenfall Wärme Berlin AG. "In this way, we increase the energy efficiency of our refrigeration plant and at the same time produce environmentally friendly heat for the connected Berlin neighborhood."
