Nobian has officially started a completely electrified salt manufacturing facility in Mariager, representing a big step within the company’s shift away from gas-powered manufacturing and toward low-carbon industrial operations.
The new installation, based on mechanical vapor recompression (MVR) technology, has been operational since January 2026. It replaces gas-fired steam with electricity by compressing and reusing procedure steam within the system—operating like an industrial heat pump.
The result is a more energy-efficient process that reduces overall energy use and cuts CO₂ emissions, while expanding site capacity by around 60%.
The expansion also considerable reinforces Nobian Dansk Salt’s position as a main supplier of high-purity vacuum salt in Europe. At complete potential, the Mariager site can now expand as much as a one million tons of annual manufacturing.
The opening coincides with a symbolic milestone: 60 years since the first brine delivery from the Hvornum salt dome to Mariager, emphasizing the site’s long industrial history in Denmark’s salt sector.
Michael Koenig, CEO of Nobian, stated: “This investment marks a major next step in electrified and sustainable salt manufacturing in Mariager and shows our confidence in the site’s future. It reduces energy use and CO₂ emissions, helps our clients’ decarbonization goals, and helps flexibility in the local energy system.
“At the same time, this investment strengthen local employment, and strategic industrial value chains. It also contributes to Denmark’s and Europe’s capacity to manufactures vital raw materials, such as salt, and the development of underground energy in salt caverns.”
The MVR system builds on earlier electrification at the site, which include a 37 MW electric boiler installed in 2022. Together, these technologies permit the facility to better align electricity demand with renewable energy availability, improving grid flexibility and supporting wind and solar incorporation.
Nobian says the Mariager upgrade is a part of a wider approach to scale low-carbon manufacturing across its operations while securing vital materials for industries ranging from food and water treatment to automotive and battery value chains.
