Different uses of Magnetite in renewable energy structures
The wind, wave and tidal industries use MagnaDense (a magnetite, iron ore product) because of its:
- high submerged density.
- ideal use as a ballasting material and as an aggregate in high density concrete.
- inert properties and resistance to leaching.
Geothermal energy projects use Magnetite in the borehole and benefit from its magnetic traceability, being a ferri-magnetic material.
Solar project developments are testing the use of Magnetite due to its high heat storage capacity, with a view to storing generated energy. This is a concept already in use for Night Storage heaters and can be utilised in various constructions for both hot and cold surfaces and cross-sections.
