Sustainable energy storage with Magnetite
Sustainable and efficient use of energy is a very actual and important topic. The mineral magnetite (Fe304) contributes as it can store energy in a very sustainable way. We mine our Magnetite (an iron ore) in the northern part of Sweden at a depth of over 1000 meters. It is an inert and environmentally-friendly material, which the construction industry uses a lot to create high density concrete.
Flexibility in electricity procurement
You can store residual heat and reuse it later. Next to that, the application potential is much broader thanks to the fact that the conversion of electricity into heat is very efficient and hardly gives any loss of energy. As a result, companies that buy electricity to produce heat for their processes can create flexibility in the procurement of electricity, enabling them to buy at the most convenient (cheap) moment. Further magnetite can be the solution to store the temporary overcapacity of green energy from solar panels and windmills.
Night Storage Heaters for residential buildings
Magnetite has been used in night storage heaters for over 25 years already. Night storage heaters, also known as off-peak heaters, have ceramic bricks composed of magnetite inside the heater unit. A huge benefit is the ability of Magnetite to store the heat during the night (or other off-peak hours) inside the bricks. The heater provides warmth when it’s required but can be charged when it’s most convenient The new generation of off-peak heating systems uses electricity from renewable energy sources and can feed the unused electricity back to the grid.
The right mix for your energy storage solution
Depending on the application and your required thermal storage need, you can use one of the several Magnetite grades we offer. We have over 50 years of experience in magnetite application. So we are confident to advise you which grades will fit best for your particular heat retaining challenge.
