Nobian commissions fully electrified MVR salt plant in Mariager
- Facility operational since January 2026 and uses mechanical vapor recompression (MVR) to electrify salt production.
- Site capacity increases by about 60%, with potential production up to 1 million tons of salt per year.
- MVR replaces gas-based steam by compressing and reusing process steam, reducing energy consumption and CO₂ emissions.
- Builds on earlier electrification including a 37 MW electric boiler commissioned in 2022 and improves the site’s e-flex/grid-balancing capabilities.
What opened
Nobian has opened a fully electrified salt production facility in Mariager, Denmark, which has been operational since January 2026. The installation uses mechanical vapor recompression (MVR) to compress and reuse process steam, replacing gas-based steam generation.
Energy and emissions
MVR keeps heat within the process, reducing overall energy consumption and lowering CO₂ emissions. The installation complements an earlier electrification step at the site: a 37 MW electric boiler commissioned in 2022.
Capacity and regional role
The expansion increases site capacity by approximately 60% and raises potential production to up to one million tons of salt per year. The opening coincides with the site’s 60-year milestone since the first brine delivery from the Hvornum salt dome and strengthens the site’s position supplying high-purity vacuum salt in Europe.
Operational flexibility and strategic value
Combined electrified assets improve operational flexibility and e-flex capabilities, enabling the site to better align electricity demand with renewable availability, support grid balancing, and contribute to Denmark’s and Europe’s capacity to produce essential raw materials and develop underground energy storage in salt caverns.
