Construction started on full-scale Triton-C

Oscilla Power recently started construction of the Triton-C wave energy converter and have now completed the preliminary build of the system hull.

Seattle-based Snow & Company is the primary contractor for the construction of the Triton-C and work is being completed at their facility in Ballard. Detailed design for the Triton-C has been completed by respected naval architects Glosten, also located in Seattle, and who have been working closely with both Oscilla and Snow to ensure that the hull construction progressed smoothly. With the hull construction is substantially complete, work will start on the internal systems (‘drivetrains’) that will convert the wave-driven motion of the Triton-C into electricity that will be exported to shore. These drivetrains are a proprietary hydraulic/electrical design that enables high efficiency power conversion with high reliability. The drivetrains are currently under construction and are expected to be delivered to Snow for integration in Q2 2020.

The Triton-C is a 100kW community-scale wave energy system developed to provide power to remote communities and facilities. The system will be tested in Hawaii at the US Navy’s Marine Corps base towards the end of 2020. It is expected that the prototype Triton-C will be tested for a year in Hawaii before being bought back to Washington state where it will generate power commercially.

Oscilla Power Awarded Phase 1 SBIR from US DoE

Oscilla Power was recently awarded a $200,000 grant by the US Department of Energy to explore how compressed air energy storage can benefit wave energy converters.

New opportunities for ocean wave energy adoption can be opened up if the inherent power variability associated with wave power generation can be mitigated through storage. Further, larger storage quantities may be able to allow scheduled or offset dispatch; for example, allowing a significant fraction of the energy that is captured during times of high wave intensity in the evening to be provided to the grid during the early AM hours when demand starts to rise and before solar generation can meet this demand.

In this project, Oscilla Power will explore integrating underwater compressed air energy storage (CAES) with its Triton wave energy converter (WEC) to mitigate the above the issues and improve the value of wave energy.

The overarching goal of this Phase 1 SBIR project is to successfully develop a concept design for an energy storage system that can be integrated with OPI’s Triton WEC to provide power smoothing and load balancing functionality. In particular, this will include down-selecting a preliminary concept and approach for energy storage on board the utility-scale Triton system. It will further demonstrate through numerical modeling, the various performance benefits in terms of power smoothing, load balancing and cost advantages that can be offered by co-locating large-scale energy storage with wave energy.

“Washington state is committed to bold leadership on ensuring a low-carbon future for our children and their children. We must continue to make wise, fruitful investments in technologies that create good-paying jobs while protecting our environment,” Gov. Jay Inslee said.

“As clean energy engages with our state’s other powerful industry sectors – aerospace, manufacturing, global health and information tech – Washington companies are poised to bring disruptive technologies to new customers all over the world,” Commerce director Brian Bonlender said. “These projects have potential to spur new business and economic growth that makes for strong, resilient communities.”

Impact Bioenergy ($550,000) of Auburn, WA, will implement systematic, community-scale food waste biocycling on Vashon Island, WA. The decentralized system will eliminate the need to ship out food waste materials and bring in amendments like compost and fertilizer. Food waste will be converted to energy for heat, power and alternative fuel vehicles, liquid organic fertilizer and sequestered CO2 used in agriculture and horticulture.

“In addition to an innovative product and passionate, talented people, now we have access to capital resources. Thanks to Governor Inslee and the Clean Energy Fund for that last ingredient, which rounds out our recipe to change the world,” said Impact Bioenergy CEO Jan Allen.

Janicki Bioenergy ($283, 158) of Sedro-Woolley, WA, will demonstrate their innovative vapor recompression distillation system that produces clean, potable water from dairy manure wastewater using thermal evaporation, steam compression, vapor recovery and water treatment. This grant will demonstrate the commercial viability of Janicki’s technology, which has the potential to provide global sanitation in places with no public water or sewer systems.

Oscilla Power ($1 million) based in Seattle, WA, will use grant funds to design, build and test a community-scale wave energy converter. The project will validate a cost-effective approach to unlock the untapped potential of ocean waves to generate massive amounts of renewable electricity around the world. Partners in the project are Glosten Associates, a Seattle-based naval architecture and marine engineering firm, and Janicki Industries, an advanced composite materials tooling and manufacturing firm based in Sedro-Wooley.

“Washington state’s Clean Energy Fund provides crucial financial support for projects like ours. Together, we’re playing a leading role in advancing marine energy research and development to benefit communities here and around the world,” said Oscilla Power CEO Rahul Shendure.

SuperCritical Technologies, Inc. (SCTI) ($283,158) of Bremerton, WA, is developing ways to use supercritical carbon dioxide (sCO2) instead of steam to generate electricity. They are investigating use of CO2 hydrodynamic bearings and related technologies such as tiny turbines and lubricants, to develop compact power plants. Modular units the size of shipping containers could generate electricity at the point of consumption, such as converting waste heat to power operations at an industrial facility, for example.

Zunum Aero ($800,000) of Kirkland, WA, will develop the first commercial-class hybrid aircraft. Partners in this grant proposal include the Clean Energy Institute at the University of Washington, Pacific Northwest National Laboratory (PNNL) and the Grainger Center for Electrical Machinery and Electromechanics at the University of Illinois, Urbana-Champaign.

“We are excited that the Washington Clean Energy Fund is joining Boeing HorizonX and JetBlue Technology Ventures to support our development of breakthrough hybrid-electric aircraft for the early 2020s. This support will extend Washington leadership to a new era of aviation, and pave the way to green, quiet skies. Our hybrid aircraft will also benefit all of us across the state, offering door-to-door travel 2 to 4 times faster than today, and affordable service to many of the 64 federally supported airports in Washington,” said Zunum Aero CEO Ashish Kumar.

This is the third round of grants awarded for clean energy research and development since the Washington State Clean Energy Fund was established in 2013. The fund also invests in revolving loan funds for commercial and residential energy efficiency, public and private utility electric grid modernization, and loan programs for solar and renewable energy manufacturing facilities.

Oscilla Power Awarded $5M DOE Grant

The DOE just announced that Oscilla Power has been selected to receive a $5.35M grant towards a 4 year long, $10.2M project that will culminate in the testing of a community-scale Triton system in Kaneohe Bay, Hawaii. 


The Energy Department today announced 10 organizations selected to receive more than $20 million in funding for new research, development, and demonstration projects that advance and monitor marine and hydrokinetic (MHK) energy systems, which generate electricity from ocean waves and tidal currents. These projects will aim to improve the performance of MHK systems and advance environmental monitoring technologies that will help protect wildlife and reduce uncertainty regarding potential environmental impacts.

The projects announced today will contribute to the development of a commercially viable MHK industry and further America’s progress in proving wave and tidal energy as viable sources for our nation’s clean energy future. Recent studies conducted by the Energy Department found that America’s technically recoverable wave energy resource ranges between approximately 900 and 1,230 terawatt-hours (TWh) per year, distributed across the coast of Alaska, the West Coast, the East Coast, the Gulf of Mexico, Hawaii, and Puerto Rico. The tidal streams resource ranges between approximately 220 and 330 TWh per year. For context, approximately 90,000 homes can be powered by 1 TWh per year. With more than 50 percent of the U.S. population living within 50 miles of coastlines, there is vast potential to provide clean, renewable electricity to communities and cities in U.S. coastal areas.

Three demonstration projects will integrate next-generation MHK hardware and software technologies into system designs. Their effectiveness will be tested during full-scale, open-water deployments over one year:

  • Dresser-Rand of Wellsville, New York, will integrate a one-megawatt air-turbine power system into the OceanEnergy oscillating water column wave energy device, doubling the power output of the previous design. The performance of the device will be demonstrated and validated during a year-long deployment proposed to occur off the coast of Oregon.
  • Ocean Renewable Power Company of Portland, Maine, will enhance the performance of its tidal turbine system by integrating several advanced component technologies. The device’s novel floating design will move the turbine near the surface to capture higher flow velocities and will help reduce the cost of installation and on-water operations, ultimately lowering the cost of energy. This project will demonstrate and monitor turbine performance during its deployment in the Western Passage off the coast of Maine.
  • Oscilla Power of Seattle, Washington, will integrate cost-reducing technology advancements into its Triton wave energy converter. Oscilla’s unique device design features tethered connections between a surface float and an underwater heave plate. This allows for energy extraction in multiple degrees of freedom, which will aim to reduce the cost of wave energy. The device will be tested at the U.S. Navy’s Wave Energy Test Site in Hawaii.


The selected environmental projects will help reduce the time and cost associated with required environmental monitoring. As a new industry, the MHK community is working with regulators to amass data to further demonstrate its environmental sustainability around issues such as noise generation from devices and device interactions with marine organisms to confirm that these fall within regulatory limits. Seven projects will improve, test, and validate cost reductions in environmental monitoring equipment that will give industry a deeper understanding of interactions between MHK systems and the marine environment:

  • BioSonics Inc. of Seattle, Washington, will develop an active acoustic monitoring system to automatically detect and locate wildlife at ranges between 200 and 300 meters. The monitoring system will track wildlife near MHK devices in three dimensions.
  • Florida Atlantic University of Boca Raton, Florida, will improve the capabilities of existing light imaging, ranging, and detection tools. While reducing production costs, this project could provide a powerful new tool to observe marine animal interactions with MHK devices, particularly in murky or low light conditions.
  • Integral Consulting, Inc., of Santa Cruz, California, will leverage an existing buoy platform to develop a cost-effective compact array of sensors that will reduce the time and cost of taking extended measurements of noise produced by devices.
  • Integral Consulting, Inc., of Santa Cruz, California,will also develop and test a standardized mapping toolset and protocol for assessing seafloor habitat conditions. New hardware and software tools will be developed to create maps of these habitats while defining baseline seafloor conditions to inform pre-construction studies.
  • University of Washington of Seattle, Washington, will optimize a drifting underwater microphone system to capture sounds. By simplifying deployment and minimizing noise pollution, this work will reduce the time and cost to measure noise produced by MHK devices over large spatial scales.
  • University of Washington of Seattle, Washington, will further develop an integrated set of instruments for monitoring marine animal interactions with MHK devices. The hardware and software will be made more flexible to allow usability among various types of MHK devices.
  • Woods Hole Oceanographic Institution of Woods Hole, Massachusetts, will adapt existing electromagnetic field sensors for use around MHK devices. This technology will help improve stability in waters near operating devices, and provide needed data to understand any potential risk that electromagnetic fields near MHK devices may pose to the environment.
