Borregaard, Norway

Borregaard commissioned a single stage hybrid heat pump in 2017. The hybrid heat pump recovers high temperature waste heat and delivers 2MW used to preheat feedwater to the plant’s steam boiler.

The project was part of a larger energy efficiency project, and with help from ENOVA, Borregaard has reduced their energy consumption by 60GWh per year. Borregaard’s plant in Sarpsborg is one of the world’s most advanced bio refineries.
