Seawater exchange is being considered as a measure against deterioration of water quality and freezing, which are becoming problems in harbors and fishing ports. It is therefore desirable to develop aseawater exchange system with low running cost to put these systems into practical use.
At the same time, development and use of new energy sources such as renewable energy have become much more common in recent years due to concerns about the global environment. Hydrogen is a clean energy source that can replace fossil fuels. Metal hydride (MH) has been studied as a method for storage of hydrogen. The MH actuator is being developed as a method for directory obtaining a mechanical force using hydrogen pressure generated by a temperature difference applied to a MH.
In this study, seawater exchange system was produced experimentally using a MH. This system could be applied to practicaluse as a sea water exchange.
