US Energy Department Awards $10.5 Million; Oscilla Power Among Recepients

December 28, 2015. The Energy Department today announced six organizations selected to receive up to $10.5 million to support the design and operation of innovative marine and hydrokinetic (MHK) systems through survivability and reliability-related improvements. As part of its MHK technology research and development efforts, the Energy Department 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. The improvements supported by this funding 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.

Projects funded under these awards will improve the survivability characteristics and reduce uncertainty regarding installation, operations, and maintenance of MHK systems operating in potentially harsh marine conditions, thus extending their lifespans and ultimately leading to a reduction in the cost of MHK-derived energy.

Three projects will increase the survivability of wave energy converters, addressing the challenges of designing MHK energy systems to operate in the ocean environment for years:

  • Dehlsen Associates, LLC, of Santa Barbara, California, is developing a wave energy converter (WEC) comprised of multiple pods that use common components to achieve economies of scale. In this project, the device structure will be optimized to improve its survivability characteristics, thus significantly reducing the cost of energy derived from the WEC.
  • M3 Wave LLC, of Salem, Oregon, is developing a WEC 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 minimize effects of sediment transport, such as water erosion, displacement, and tilting of the device, and to increase the lifetime of the system by reducing maintenance requirements in commercial-scale deployments.
  • Oscilla Power, Inc., of Seattle, Washington, is developing a WEC consisting of a surface float that is tethered to a base suspended in the water. This projects aims to optimize the device’s storm-survival configurations, which will decrease the loads the device experiences during extreme conditions, thus lowering the resulting cost of energy.
