Gallery: Fleets of Wave Power Ships Could Harvest Cheap Energy from the...


One of the major concerns over the current crop of renewable energy technologies is that they’re pretty expensive compared to dirtier, more conventional fossil fuels. However researchers at Boston University and the Fraunhofer Center for Manufacturing Innovation think they’ve found a way of producing cleaner, cheaper wave generated energy on demand. Their idea would send a fleet of wave-powered ships out into the middle of the ocean, where they would drop anchor and start gathering energy from the movement of the surrounding waves. This energy would then be stored in on-board batteries, and once fully charged the ships would return to shore where the energy could be distributed into the grid.

    great to see the idea.

    why not set up on sailing ships and provide propulsion or electric power to reduce the emissions.

    vessels about 300 meters can generate its own power with the rolling of the vessel movement and provide some comfort to vessel too.

    I agree with L. Appleton. They should store the energy as hydrogen gas. I also agree with C. Angelo

    I completely agree to C. Angelo’s post above.
    Why can’t the huge amount of energy (MW) be used to run the Ships themselves?
    If it can then it’ll be huge saving over Fossil Fuel Usage and we can have the marine equivalents of Electric Vehicles.

    Making the batteries to store the energy causes HUGE environmental impact…and then the batteries have a finite lifespan. The idea is great, we just need to come up with a storage mechanism with a lower environmental impact.

    Could this technology be used to meet the power needs of seafaring vessels, rather than storing the energy and bringing it back to land?

    I don’t see how this is cheaper. You spend fossil fuels to drive out to the ocean and then back…
