WaveRoller Obtains DNV GL Verification

Installation of WaveRoller

WaveRoller, the wave energy device created by wave energy developer AW-Energy has received independent performance verification, taking the wave power industry one step closer to commercialization. WaveRoller received its validation after operating in fully exposed ocean environment during testing campaigns in 2012 and 2013. AW-Energy submitted detailed data covering wave conditions and device performance for external verification. Independent verification of the WaveRoller power matrix signifies a major milestone for near-shore wave energy converters on their way to commercialization and large scale deployment. The WaveRoller device is equipped with a large array of sensor and measurement equipment that monitor the operating conditions and performance of the device. The recorded data is instantly available in the control room in Portugal, as well as by remote connection. The 2012 and 2013 grid-connected and fully operational hours delivered much data for various device settings and operating conditions. Out of these, a half-month most representative sample with continuous operation has been independently selected for verification. The extensive study and performance verification was conducted by the leading technical advisory to the renewable energy industry, DNV GL (formerly Garrad Hassan & Partners Ltd)

Wave Power Generation – US Navy Hawaiian Project

Navy eyes Kaneohe wave power testing expansion The Navy hopes to expand its testing for ocean wave energy power generation in Hawaii, having been testing an energy buoy in about 100 feet of water off Marine Corps Base Hawaii in Kaneohe Bay for about 10 years. The Navy now hopes to put two more buoys in water more than 200 feet deep, and the greater depth will allow it to test larger devices closer to the size it needed to generate energy for customers.

Proposed Wave Energy Park on Oregon Coast
