The starting-point for the development was to enable the cell to use seawater as an electrolyte without any form of pre-treatment. The main challenge related to this is the presence of Magnesium in seawater taking part in the electrochemical reactions and forming a substrate of the mineral form of Magnesium Hydroxide (Mg(OH)₂) or Brucite as it often is referred to. This tends to clog conventional membrane cells. The new development reduces the impact of Brucite – consequently the cell can operate continuously using raw seawater as feed. It can off course also use brine as electrolyte.

The development has generated 4 patent applications. If you want to learn more, don’t hesitate to contact us.
