Wavepiston

About This Project

No attempts to harvest energy from waves have resulted in economically viable and competitive technology. Currently the cost per watt of usable wave energy is high, due to a focus on energy conversion methods and efficiency, rather than on mooring and grid connection, accounting for more than 90% expenditure.

 

Wavepiston is a breakthrough near-shore wave power technology producing energy from waves at a competitive price in comparison to the most efficient renewable energy technologies. The system consists of identical modules mounted on a string, pumping pressurized water to shore for energy generation. Using Wavepiston’s patented “force cancellation” principle, the system is able to reduce the amount of forces on the mooring and structure to 1:10, requiring a simpler structure and reducing capital costs. The Wavepiston system offshore application ensures it is also a suitable fit for remote islands and isolated coastal communities.

 

The Wavepiston system was conceived in 2006. In 2010 numerous tank tests were performed with a system 1:30 the size. In 2013 a proof of concept was carried out offshore with a system 1:9 the size and results were better than predicted.
