This is an area where the materials of construction have an important impact.
As stated previously there is a requirement for the use of plastic materials within the construction of an electrolyser assembly. The use of this material will have an impact upon the pressure temperature of the installation which has to be taken into account.
The main considerations are whether the installation will be indoors or outdoors typically under a shade. Solar gain or freezing is not usually problematical for an outdoor installation in operation as the seawater flow is relatively massive compared to the Electrolyser mass and the process heat dissipation, solar gain or freezing ambient temperatures.
It is conventional however to have part of the system idle due to a plant redundancy. In this instance solar gain and freezing are problematical unless the idle electrolysers are drained or alternative protection methods are employed, e.g. trace heating.
