FOA 2080 Lab Support AOI2b CEC

Projects funded under the CEC AOI, will support efforts to develop CEC technologies that can responsibly and cost-effectively harness the Nation’s riverine resources, leading to improved resiliency and diversity of the Nation’s energy generation system. CEC technologies may ultimately be easier and more cost effective to deploy in the many regions of the United States, especially in remote locations, that lack robust port infrastructure and vessel availability. But there are many technical challenges remaining before these potential opportunities can be realized. The DOE Reference Model Report identifies deployment (moorings, power cables, and device installation), operations and maintenance as the most important cost drivers for CECs, while suggesting that improving other components, such as rotors and drivetrains does not provide as much cost savings potential. WPTO has previously supported R&D projects that have developed and tested components, control strategies, and generator technologies, and one CEC system prototype project. However, today’s CEC systems still require potentially complicated installation, operation, and maintenance (IO&M) strategies. Successful projects will expand the number and geographic diversity of locations where CEC technologies are commercially viable, while simultaneously advancing the state of CEC technologies. Further, the CEC AOI requires the development and use of modular system designs, enabling CEC projects to be easily optimized for a wide range of deployment locations and electricity load needs. CEC AOI projects will design, fabricate, and open-water test modular CEC river system that incorporate and advance IO&M techniques which require only limited use of port and vessel infrastructure.

This report summarizes the best available data on U.S. marine energy resources at the national, state, and regional scales. Results are primarily based on U.S. Department of Energy (DOE)-funded marine energy resource assessments for wave, tidal currents, ocean currents, ocean thermal gradients, and river currents.

Marine and hydrokinetic (MHK) energy contributes to national energy objectives by providing clean energy to reduce oil dependency and lower carbon emission. The long-term water program goal is to significantly reduce the levelized cost of energy (LCOE) for marine and hydrokinetic devices and enable significant deployment of grid-scale cost-competitive MHK by 2030. In 2017, the Department of Energy (DOE) Water Power Technologies Office (WPTO) issued a Funding Opportunity Announcement (FOA), entitled Marine and Hydrokinetic Technology Development and Advancement, to support MHK research and development for current energy converters (CECs). This project will use model-scale tank testing and fluid-structure-interaction (FSI) simulations to investigate the behavior of hydrofoils with large deflections and the effect of the radial and rotational deflections on cross-flow turbine performance with the ultimate goal of determining the maximum allowable deflections consonant with efficiency and a robust, durable structure. Care will be given to developing a robust, validated modeling and simulation approach, which will be used in the design of ORPC’s full-scale turbines, and will be applicable to the design of other MHK devices.

This project focuses on collecting and analyzing data to inform standards and certification development efforts by the International Electrotechnical Commission (IEC) Technical Committee (TC) 114 Ocean Energy. IEC TC114 is responsible for developing standards that define the international requirements for all ocean energy devices in the future. Participation, including reviewing and proposing data-based improvements to recommended standards, in these groups is essential because such interactions broaden and streamline adoption of marine and hydrokinetic (MHK) devices in the global marketplace and ensure that the interests of the U.S. industry and the DOE are established and maintained.
