The Water Power Program's marine and hydrokinetic research and development (R&D) efforts focus on advancing technologies that capture energy from the nation's oceans and rivers. Unlike hydropower, marine and hydrokinetics represent an emerging industry with hundreds of potentially viable technologies. The program is therefore leading efforts to prove functionality; evaluate technical and economic viability; and generate cost, performance, and reliability data for a variety of devices.
Marine and hydrokinetic energy technologies convert the energy of waves, tides, and river and ocean currents into electricity. The Department of Energy's "Marine and Hydrokinetic 101" video explains how these technologies work and highlights some of the Water Power Program's efforts in R&D in this area.
The program's efforts fall under three categories: technology development; market acceleration and deployment; and resource assessment and characterization.
The Water Power Program's technology development activities center on reducing the technical barriers to marine and hydrokinetic device development, improving device reliability and performance, and understanding and evaluating various technology types. Specific activities include the following:
- Supporting the design, development, testing, and deployment of marine and hydrokinetic devices and components in both laboratory and open-water settings
- Developing tools and models that support the design, development, and optimization of marine and hydrokinetic devices
- Evaluating and assessing information on the cost and performance of marine and hydrokinetic device designs.

International Standards are technical specifications and documents written by experts from across the globe to describe best practices, based on industry experience, for how a device should be designed, built, and/or operated to be safe, compatible, and interoperable. For marine energy, standards exist or are being developed to characterize features such as power performance assessments and acoustic characterization, among others. International Standards are not mandatory unless they are adopted as part of a certification scheme, regulatory process, and/or are referenced as a prerequisite as part of a funding solicitation.

The Water Power Program has released reports and maps that assess the resource potential of the nation's waves, tidal, ocean, and river currents, and ocean thermal gradients. Learn more about the resource assessment and characterization of the nation's marine and hydrokinetic resources.
