The plant constitutes a basic part of the tower of the Wind Energy Converter (WEC), whose rotational energy directly initiates the operation of a compressor through a gear. Temperature and pressure levels of the water/steam are then raised to required values, allowing evaporation to take place. Evaporation of water leads to condensation of fresh water, leaving salt behind. The MVC method exploits the 75% of the required energy directly from the wind turbine and 25% from the WEC through an adapted generator. Thereby, the process does not rely on any conversion of wind energy to electricity and then to mechanical energy, thus eliminates any relevant energy losses. Additionally, no separate power conversion plant is required, which is a major saving on investment and operational costs.
The WEC tower integrates all functional components of the desalting unit, including the seawater reservoir, filters, pump units, compressor, evaporator and drinking water storage tank. Industrial partners are sought within the wind energy and/or desalination sectors for a joint development of the technology.
