Carnegie Wave Energy, based on Perth, Australia, announces their new technology of wave-powered desalination plant. The plant will be the first in the world
capable of delivering both clean energy and fresh
water.
Named after a Greek sea goddess, CETO harnesses the
enormous renewable energy present in the ocean's waves and converts it
into two of the most valuable commodities underpinning the sustainable
growth of the planet; zero-emission electricity and zero-emission
desalinated water.
Unlike any other wave energy systems, CETO wave power converter is the first unit to be
fully-submerged and to produce high pressure water from the power of
waves. The system will be situated on the seabed 25-50 meters below water. This makes it safe from the extreme forces that can
be present during storms and creates no visual impact.
Above picture depicts the design of CETO. The top "flying-saucer" like device will be floating up and down, with the base (the yellow color structure) secured in the seabed. The "up" and "down" motion will create a pumping mechanism which push the sea water up to the shore (as shown on the first picture).
By delivering high pressure water ashore, the technology
allows either zero-emission electricity to be produced (similar to
hydroelectricity) or zero-emission freshwater (utilising standard
reverse osmosis desalination technology). The system can also be used
for co-production of zero-emission electricity and freshwater.
