Cape Verde: the next proving ground for wave powered desalination after Australia?

Archipelago Cape Verde off the northwest coast of Africa will host a wave-driven desalination system to eventually supply more than 48,000 people with drinking water.
A grant of US$930,000 has been awarded by the African Development Bank-hosted Sustainable Energy Fund for Africa (SEFA) to help develop the project.
Spanning 10 islands, Cape Verde faces water shortages. Although limited groundwater sources have been sufficient to supply a 500,000 population, increased tourist demand has forced the government to look to additional sources.
The latest initiative, called Water2O, will be developed by a local subsidiary of US company, Resolute Marine Energy (RME).

With a capacity of 4,000 m3/day, it is hoped the site selected for the “off-grid” technology will eventually enable the project to be scaled up to 20,000 m3/day.
RME claimed the reverse osmosis based system has a total cost of €20 million, with a six year payback, offering a running cost of €1/m3.
Although a press release from the African Development Bank Group stated the project will be the “world’s first wave-driven desalination system”, a similar project is already underway in Australia.
At the end of October 2013 Australian company Carnegie Wave Power completed a design of a wave-powered desalination pilot plant on Garden Island (read WWi article).
