A company called Carnegie Wave Energy is pushing the boundaries of wave-energy technology, Australian island and coastal communities are already taking advantage of it.
Wave energy – at least in theory – has the potential to provide one third of Australia’s electricity needs. The challenge has been to design a wave energy system that can resist the brutal power of the ocean, and to find a niche in the market in the face of plunging costs of solar energy and other renewables.
The Carnegie plan, called CETO, consists of a series of buoys and pumps that are tethered to the ocean floor.
When jostled by wave action, the pumps send water through pipes to a land-based turbine system, which produces hydroelectric power. Aside form the hydroelectric power is an added bonus, the turbines also power desalination filters, producing fresh and perfectly drinkable water.
The buoys also act as artificial reefs which in time will help promote marine life, another side bonus. Thanks to the predictability and regularity of the tides and the promise of guaranteed wave action, it means that the power produced is essentially endless, if the technology can be scaled up to create financially viable electricity.
Carnegie CEO, Dr Michael Ottaviano spoke to Huffington Post about the future of CETO and how wave energy is more efficient than wind & solar. Check out the interview below:
