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 MagnaDense 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.
