Glencore’s Nikkelverk refinery in Norway has successfully implemented a portfolio of new energy management technologies which will save over 30GWh energy annually.

From great to small, these include initiatives based on pressurised air, steam, ventilation, reusing waste heat and process improvements. The projects have been made possible through $6 million in funding from ENOVA (the Norwegian government energy fund).

Glencore has installed new tanks, electrical contacts and energy-efficient anodes to reduce its energy consumption. Waste heat from their sulphuric acid plant is now being used to replace electrically generated steam.

The refinery is working to replace any remaining older anodes with efficient alternatives. This will save a further 17GWh per year.
