CleanTechnica has an article on a round of funding from the US DOE for tidal and wave power research - US Taps Into 1400 Terawatt Hours Of Clean Ocean Power.
As the US offshore wind power industry slowly (very slowly) cranks up to speed, let’s not forget that US coastal waters also represent a huge, as-yet-untapped energy resource in the form of waves, tides and currents. The Department of Energy estimates the total could come up to 1400 terawatt hours of electricity per year, enough to power millions of homes. The problem is getting the private sector to take the plunge into uncharted technological waters, and to that end DOE has just announced a new round of $16 million funding, including public-private partnerships, to help kick things into gear.
The money will go to 17 projects that cover efficiency improvements in wave and tidal generators as well as data collection and environmental surveys.
