The aim is to develop high capacity and cost efficient magnesium (Mg) based seawater batteries with increased environmental compatibility suitable for long term operation of marine observatories. The partners plan to improve the performance of Mg-seawater batteries in different hydrodynamic conditions by finding the optimum combination of anode material, electrolyte additives and cathode design to achieve longevity of minimum 5 years and a capacity of 25kWh.
Aqueous primary Mg batteries have several advantages for marine applications as they can operate at any pressure, have greater power storage capacities and are cheaper than lithium-ion batteries. Furthermore, since the unlimited supply of seawater serves as the electrolyte, the size and weight of the battery system can be considerably reduced. Possibly applications are autonomous subsea observation systems in the oil & gas and aquaculture industry.
SeaMag is funded by the MarTERA partners Research Council of Norway (RCN), German Federal Ministry for Economic Affairs and Energy (BMWi) and National Academy of Sciences of Belarus (NASB) and co-funded by the European Union.
