Water scarcity is a growing challenge in a large part of the world. Desalination of seawater is an energy intensive process and in coastline areas where water scarcity coincides with a significant wave climate, desalination of seawater is an attractive application for utilisation of wave energy.
The Ocean Oasis desalination device uses wave energy directly to desalinate seawater without going via the production of electricity. It is estimated that the Ocean Oasis device can deliver water to shore at a cost of 0.9 USD/m3 and 0.5 USD/m3 for a NW Arica and a South Africa wave environment respectively.
The next step in the development of the concept is a small scale demonstration project. The demonstration unit will include all the features of the full scale unit, be capable of delivering desalinated water to shore, and will serve to demonstrate the feasibility of the concept and generate sufficient interest to realise a commercial full scale plant.
