Shiver Me Timbers 2.0: DOE Giving $12M to Marine Energy

The U.S. Department of Energy has issued a Funding Opportunity Announcement that will seek to award up to $12 million to marine energy research projects.

This follows $7.3 million issued for marine power last year.

The projects can run the gamut, from conventional hydropower to wave machines and beyond. You’ve heard of the usual ones—underwater tidal turbines, wave bobbers, etc. Now here are some of the more unusual concepts:

  • Small hydroelectric power stations that harvest electricity from the excess pressure inside municipal water systems. Call it microhydro.
  • Electricity from osmotic pressure gradients, i.e., the pressure differences that can be created when fresh water meets sea water. Aquaporin in Denmark, among others looking at it.

2009 has not been the best year for marine energy. Pelamis hid, but eventually had to confess, that the three wave devices it put off the coast of Portugal last year are actually no longer at sea. Aquamarine scrapped tidal power, but kept wave.

Still, if standards get developed, it could take off. Although much of the tidal work takes place in Ireland and the U.K., startups and researchers are also clustered around California, Florida, Australia and South Africa.

    I’m still optimistic about the sector. There’s just so much energy there waiting to be tapped. Wave power in particular is promising, given that it doesn’t require immersion of turbines in corrosive seawater. I believe Pelamis has been plagued with financial problems more than anything else. They might not make it but I expect others to keep trying.

    Seems so eco-hostile. . .I mean come on - tether cables, conductor cables, submerged electronics
    serious amperage per install, corrosive environment, boats, little mermaids and the like just tryin’ to get along.  I get the idea, and like tapping all that mechanical power, but again, as Cool Earth Solar CEO Rob Lamkin put it, “it’s a materials issue!”

    Shame so little.  Baseload power available to any coastal community should be a priority me thinks…

    It’s definitely worthwhile and it probably should have been more, but marine is still such a tough task. The government is probably trying to put more into near term stuff It is in the stage of those olde tyme movies they used to show at Shakey’s of biplanes, triplanes and guys flapping their arms in an effort to fly.

    Pelamis was financial in the end, but there have been steady trickles of mechanical problems.
