Green energy in Baltic Sea
The condition of the Baltic Sea is critical as the oxygen-poor bottoms are growing every year. The technology from Scandinavian Ocean Minerals removes oxygen-consuming bottom sediment and organic material and thus oxygenate the seafloor, supporting the recovery of the Baltic Sea.
The organic material, the sediment, is disposed and refined into Green energy, for example, biogas, hydrogen gas or converted into green carbon. The sediment also contains approximately 20 percent silicon used for solar cells, semiconductors and batteries.
On the Bothnia Bay seafloor lies small potato-sized lumps – nodules – that contain minerals. In the Baltic Sea lies sediments.
Via an air-lift technique, developed by Scandinavian Ocean Minerals, the seafloor is gently harvested for nodules or bottom sediment.
On board the ship, nodules are filtered or, if sediment centrifuged
Water and material that is not used is returned directly to the seafloor, which becomes oxygenated in the process.
Nodules and sediment are transported to land where nodules are refined into, among other things, manganese, iron, silicon (used for batteries, solar cells and semiconductors) while sediment becomes biogas, hydrogen gas or green coal (used for fossil-free steel).
