The Department’s latest nationwide wave and tidal energy resource assessments identify up to 1,400 terawatt hours of potential generation per year. One terawatt-hour of electricity is enough to power 85,000 homes.
About $13.5 million will go to 8 projects to help US companies build durable, efficient wave and tidal devices that reduce overall costs and maximize the amount of energy captured. The projects will develop new drivetrain, generator, and structural components as well as develop software that predicts ocean conditions and adjusts device settings accordingly to optimize power production.
For example, ABB will develop an affordable, efficient generator that is half the size of a traditional generator, while Ocean Energy USA will develop and test a hull design for a floating wave device. Dehlsen Associates will develop new software for its Centipod wave device to predict future wave conditions and adjust system settings to maximize power output.
About $2.4 million will go to 9 projects that will gather and analyze environmental data from wave and tidal projects as well as potential development areas. As this nascent energy industry grows, these projects will help ensure that potential environmental impacts are addressed proactively and that projects can be developed efficiently and responsibly.
The Bureau of Ocean Energy Management is providing $300,000 towards these awards.
