Testing Update

Ever since registering more than a year ago for the Wave Energy Prize, our teams have eagerly anticipated the opportunity to test their 1/20th-scale WEC prototypes in the Navy’s Maneuvering and Seakeeping (MASK) Basin, at Carderock, Md. In a building with a footprint of more than five acres, what developer wouldn’t be giddy with excitement to test a new technology in the nation’s premier wave-making facility containing more than 12 million gallons of fresh water?

The beginning of August marked the beginning of the final round testing, and some of our Finalist Teams have already completed their 1/20th scale model tests in the MASK Basin. Others are still awaiting their turn. M3 Wave was first in the tank, followed by Waveswing America, Harvest Wave Energy (Team FLAPPER), AquaHarmonics, CalWave Power Technologies, Oscilla Power and Sea PotentialRTI Wave Power is testing its prototype this week, and SEWEC is onsite building its device.

“Watching our Finalist Teams’ WEC concepts come to life at the MASK Basin has been a thrill,” said Alison LaBonte, Marine and Hydrokinetic Technology Program Manager in DOE’s Water Power Technologies Office. “We’re looking forward to the Judges’ analyses of the nine weeks of testing and learning how many and which technologies surpassed our goal of doubling the energy capture efficiency of wave energy converters.”

Armed with Science: The Navy’s Indoor Ocean

As many teams mentioned during the Wave Energy Prize Team Summit in April 2016, the Finalists are incredibly excited to test their 1/20th-scale WEC prototypes at the nation’s premier wave-making facility, the Naval Surface Warfare Center’s Maneuvering and Seakeeping (MASK) Basin, at Carderock, Md. With testing beginning in less than two weeks, let’s take a closer look at this unique facility, which was featured in the official U.S. Department of Defense science blog, Armed with Science, last year.

Wave Energy Prize Finalist Teams and Alternates Showcased at Waterpower Week

Photocollage_640x480_V2Wave Energy Prize Finalist and Alternate Teams recently had a unique opportunity to showcase their technologies and network with industry, academic, and government stakeholders during Waterpower Week 2016 in Washington, D.C.

The week’s events kicked off during the National Hydropower Association Annual Conference’s opening plenary session on Monday, April 25 when José Zayas, Director of the U.S. Department of Energy’s Wind and Water Power Technologies Office, highlighted the work of the teams to the more than 700 conference attendees.

On Monday and Tuesday, the teams had their 1/50th-scale WEC models on display, meeting with Zayas, Cristin Dorgelo, Chief of Staff of the White House Office of Science and Technology, and other event attendees during the conference’s coffee breaks. On Tuesday afternoon, teams switched gears and took part in a Wave Energy Prize Team Summit, a key part of Waterpower Week, where they were able to meet each other and share ideas; learn about the requirements of upcoming Technology Gates 3 and 4; and participate in on-camera interviews discussing their thoughts on the role of government in innovation, their teams’ successes so far, and the challenges they are overcoming in the upcoming final phase of the Prize. The teams then traveled to the MASK Basin at Carderock, Md., on Wednesday morning to better understand the logistical and technical requirements related to 1/20th-scale testing, and to tour the world-class facility where they will test their prototype devices beginning in August.

Two Wave Energy Prize Qualified Teams Selected by DOE to Receive Share in $10.5 Million for a Separate WEC Survivability Funding Opportunity

The New Year started with some good news for M3 Wave LLC and Oscilla Power, Inc. as these Wave Energy Prize Qualified Teams were two of six organizations selected to receive a share of $10.5 million under the U.S. Department of Energy’s (DOE’s) Durability and Survivability funding opportunity. This funding, which is separate from the Wave Energy Prize, targets the advancement of marine and hydrokinetic (MHK) device durability and survivability, features—not being tested for in the Wave Energy Prize—that make devices withstand the harsh conditions encountered in real-world marine environments.

  • M3 Wave LLC, of Salem, Ore., is developing a wave energy converter that sits on the ocean floor and harnesses energy from the pressure waves beneath ocean waves. This project will develop modeling tools to explore ways to 1) minimize effects of sediment transport, effects such as water erosion, displacement, and tilting of the device; and to 2) increase the lifetime of their system by reducing maintenance requirements in commercial-scale deployments.
  • Oscilla Power, Inc., of Seattle, is developing a wave energy converter consisting of a surface float that is tethered to a base suspended in the water. This project aims to optimize the device’s storm-survival configurations, which will decrease the loads the device experiences during extreme conditions.

DOE’s National Renewable Energy Laboratory and Sandia National Laboratories will also provide numerical modeling resources and expertise to the teams as they develop these next-generation ideas.

The design improvements will help these devices last longer, cost less to maintain and capture even more sustainable energy from the enormous potential of the nation’s oceans and rivers. Extending the lifespans of wave energy converters will ultimately lead to a reduction in the cost of MHK-derived energy. As part of its MHK technology research and development efforts, DOE is working to harness the largely untapped renewable energy in waves, tidal, ocean and river currents that could provide clean, affordable energy to homes and businesses across the country’s coastal regions.
