Marine & Hydrokinetic Data

This project estimates the naturally available and technically recoverable U.S. wave energy resources, using a 51-month Wavewatch III hindcast database developed especially for this study by National Oceanographic and Atmospheric Administration's (NOAA's) National Centers for Environmental Prediction. For total resource estimation, wave power density in terms of kilowatts per meter is aggregated across a unit diameter circle. This approach is fully consistent with accepted global practice and includes the resource made available by the lateral transfer of wave energy along wave crests, which enables densities within a few kilometers of a linear array, even for fixed terminator devices.

The total available energy resource along the U.S. continental shelf edge, based on accumulating unit circle wave power densities, is estimated to be 2,640 TWh/yr, broken down as follow: 590 TWh/hr for the West Coast, 240 TWh/yr for the East Coast, 80 TWh/yr for the Gulf of Mexico, 1,570 TWh/yr for Alaska, 130 TWh/yr for Hawaii, and 30 TWh/yr for Puerto Rico. The total renewable wave energy resource, as constrained by an array capacity packing density of 15 megawatts per kilometer of coastline, with a 100-fold operating range between thresholds and maximum operating conditions in terms of input wave power density available to such arrays, yields a total recoverable resource along the U.S. continental shelf edge of 1,170 TWh/yr, broken down as follows: 250 TWh/yr for the West Coast, 160 TWh/yr for the East Coast, 60 TWh/yr for the Gulf of Mexico, 620 TWh/yr for Alaska, 80 TWh/yr for Hawaii, and 20 TWh/yr for Puerto Rico.

Marine and Hydrokinetic Technology Database

The U.S. Department of Energy's Marine and Hydrokinetic Technology Database provides up-to-date information on marine and hydrokinetic (MHK) renewable energy, both in the U.S. and around the world.

The database includes wave, tidal, current, and ocean thermal energy, and contains information on the various energy conversion technologies, companies active in the field, and development of projects in the water. Depending on the needs of the user, the database can present a snapshot of projects in a given region, assess the progress of a certain technology type, or provide a comprehensive view of the entire MHK energy industry.

Results are displayed as a list of technologies, companies, or projects. Using the search options at left, data can be filtered by a number of criteria, including country/region, technology type, generation capacity, and technology or project stage. The user can also learn more about the different marine and hydrokinetic technology types by selecting the "Technology Glossary" option.

Hydrodynamic Testing Facilities Database

The Hydrodynamic Testing Facilities Database provides data on a range of test capabilities and services available at commercial, academic, and government facilities and offshore berths within the United States. The operator and facility tables were prepared using data made available by facility and berth operators. All operators, facilities and berths represented in the tables are backed up by an individual profile page.

For more information on MHK resources, access the resource maps page on the Marine and Hydrokinetic Technology Resource Assessment and Characterization site.
