ABB to help decarbonise district heat supply in Denmark

02 Dec 2021

ABB will deploy its complete electrical, instrumentation and control (EIC) package, motors and variable speed drives for the powerhouse of the heat pump, which will be the world’s largest seawater heat pump based on CO2 as refrigerant.

With Esbjerg facing the UNESCO world heritage area of the Wadden Sea, the careful selection of the right pump was essential. The 50MW seawater heat pump system from MAN Energy Solutions, a long-standing customer of ABB, converts electrical energy into thermal energy and uses toxicologically safe CO2 as a refrigerant for the entire system cycle.

As part of its 2030 strategy to pursue a 100% fossil free heat production with zero loss of applied resources, DIN Forsyning is developing a new hybrid renewable district heat plant to replace heat currently supplied by the Esbjerg coal-fired combined heat and power (CHP) plant.

ABB’s technology will contribute to the replacement of the coal-fired plant as the main source of heat for the city of Esbjerg and get closer to the goal of reducing carbon emissions in the city. It will also be deployed to ensure that the entire heating network can be powered from renewables, and distributed to the plant, through connections to the offshore wind turbines in the North Sea.

ABB will also supply a medium voltage variable speed drive, motors, as well as electrical and control solutions to support the high efficiency of the system and the accurate control of the massive heat pump.
