An empowered and highly motivated staff operates the drilling field, located south-west of Hobro, connected with a 26 km underground pipeline to the plant in Assens where evaporation processes deliver various types of salt, leveraging a flexible energy production, including grid balancing services.

The high-quality salt is supplied globally to the pharmaceutical industry and in Europe to customers within feed and food, the electrolysis industry and deicing.

At the site, we have one of our key customers - Mariager Salt Specialties A/S - in a direct connected off-take. The rest of the production is shipped from our own harbor, situated by one of Denmark's most beautiful fjords, Mariager Fjord.

At Nobian/Dansk Salt A/S, we are fully committed to implementing our sustainability strategy, Grow Greener Together. Our primary objectives include delivering timely and exceptional customer service, contributing significantly to the green transition, ensuring environmental stewardship, and continually nurturing the growth of our employees and the local community, in which we all play an integral part. Nobian’s four values serve as our guiding principles.

In recent years, Nobian Dansk Salt has invested in the electrification of its operations, including an electric boiler and an electrified salt production facility based on Mechanical Vapor Recompression (MVR) technology. The opening of the new salt production plant in 2026, coincided with a milestone for the site, marking 60 years since the first brine delivery from the Hvornum salt dome to Mariager. Since then, salt production has remained a key industrial activity in the region. With the latest expansion, the site’s potential production capacity can reach up to one million tons of salt per year.

Building on its salt expertise, subsurface knowledge and the existing Hvornum salt dome, the site also plays an important role in exploring the development of underground energy storage caverns in Denmark, which can help store renewable energy and strengthen the flexibility of the energy system.  

In the Green Hub Mariagerfjord project, we foster collaboration between local industries to enhance sector coupling among industrial companies, energy production, and district heating. By focusing on small, impactful steps, this initiative creates value through cross-sector collaboration, driving sustainable development and energy efficiency in the region.

We are also proud of our Flex-department with special care and of our strong collaboration with Mariagerfjord Municipality and Mariager Saltcenter. 

The Plug and Abandonment of HV-5 project involved the process of safely sealing and decommissioning a well to prevent any environmental hazards. Here we employed the double barrier principle, ensuring robust protection. Utilizing 75 m³ of cement, we set five individual plugs, providing secure and long-term stability for the abandoned cavern.
