When is salt a problem, and why is it a problem?

Salt works as a corrosive agent

The salts normally present in sea air are dissolved within small droplets of water, resulting in corrosion problems for nearshore and offshore wind turbines. When salt absorbs humidity from the air, it accelerates the corrosion and oxidation rate inside the wind turbine structures, due to the mineral's high corrosion capacity.

Conventional filtration is not enough to remove corrosive salts from the air. In offshore environments, these salts are usually dissolved in moisture. This corrosive solution tends either to be sticky and clog up the filter or pass right through in liquid form. The lack of the right filtration system means that humidity with corrosive salts is spread throughout the insides of the nacelle and tower
