Mariager, Denmark, 2022
The installation of an electrical boiler at our site in Mariager, Denmark, means we can now make part of our steam out of excess renewable energy, thereby reducing our natural gas consumption and associated CO₂ emissions. In addition, it helps stabilize the grid by operating when an excess of renewable electricity is available.
The new boiler makes our salt production much greener. It will enable us to save seven million m³ of natural gas per year, the equivalent of the average amount of gas used by more than 5,500 households.
The boiler operates at 10,000 volts and consists of three electrode bundles in a vessel where the steam is produced. It can convert 50m³ water into steam per hour – which is the full load demand for the salt plant evaporation process when running at full pressure.
This greater flexibility in our steam production allows us to reduce our costs and ensure our production plant remains fully operational when one of our other boilers needs maintenance.
