Wave Energy Device Deployed in Hawaii

Northwest Energy Innovations (NWEI) has successfully deployed its Azura wave energy device at the United States Navy’s Wave Energy Test Site (WETS) near Kaneohe Bay, Oahu, Hawaii. The device will be deployed for 12 months of grid-connected testing as part of a rigorous program to commercialize the Azura technology.

“As the first grid connected wave energy device in the U.S. that will be tested and validated by an independent party, this deployment marks a major milestone for our team and the marine renewable energy industry,” said NWEI Founder and CEO Steve Kopf. “A special thanks to Sea Engineering, our deployment contractor, for their tireless efforts in completing the assembly, launch and installation of the Azura at WETS,” Kopf added.

Deployment and testing of the Azura at WETS is supported by the U.S. Department of Energy, the U.S. Navy, and the University of Hawaii. The University of Hawaii is responsible for data collection, analysis and reporting as a means of independently validating the technology performance. The data will also be delivered to the U.S. Department of Energy and the U.S. Navy for their use in ongoing efforts to validate wave energy technology and advance the marine renewable energy industry.

In addition to evaluating system performance in the open ocean over an extended period of time, data collected during the deployment will enable NWEI to develop a more accurate assessment of the technology’s Levelized Cost of Energy (LCOE), which accounts for capital cost, project development cost, life cycle costs and annual energy production. The data will also be used to validate computer simulations to support commercialization of the Azura technology.

“Standards, rigorous testing, and transparency are the foundations of our development program for the Azura technology. We believe that independent verification of performance data is imperative to achieving commercialization,” said Kopf.

This pilot project builds on NWEI’s deployment of a prototype at the Northwest National Marine Renewable Energy Center’s test site off the coast of Oregon in 2012. The 2012 deployment was also supported by the U.S. Department of Energy, and NWEI applied experience gained from that testing to refine the Azura design, with a focus on optimizing the technology’s LCOE through increased power output and improved durability, maintainability and survivability.

Development of the Azura technology is a collaborative effort between NWEI, Callaghan Innovation and Energy Hydraulics Ltd (EHL). Callaghan Innovation led the conceptualization and early development of the technology in New Zealand, and NWEI recently secured a global exclusive technology license from Callaghan Innovation to commercialize the Azura technology. EHL plays a critical role in advancing the technology and is responsible for the engineering, fabrication, and testing of the power conversion system.
