World’s largest wave farm off Orkney

wave farm

Scottish ministers have announced funding for what has been described as the world’s biggest wave energy farm.

Ocean Power Delivery Ltd has developed a novel offshore wave energy converter called Pelamis. Building on technology developed for the offshore industry, the Pelamis has a similar output to a modern wind turbine. The first fullscale pre-production prototype has been built and tested at the European Marine Energy Centre in Orkney.

Scotland’s Deputy First Minister Nicol Stephen announced a £13m funding package that will also allow a number of other marine energy devices to be tested. The biggest single handout of more than £4m will go to a Scottish Power subsidiary, CRE Energy, which will build the wave farm. Scottish Power is planning a venture which it believes could create enough power for 2,000 homes.

Ocean Power Delivery Ltd anticipate that future `wave farm’ projects would consist of an arrangement of interlinked multi-machines connected to shore by a single subsea cable. A typical 30MW installation would occupy a square kilometre of ocean and provide sufficient electricity for 20,000 homes. Twenty of these farms could power a city such as Edinburgh.

    This looks like very interesting technology. These things are BIG, though, the 40-unit ‘wavefarm’ is particularly intimidating. If a ship without power drifted into that in a storm, I don’t know which would come off worse.
    Last September OPD and E.ON agreed to develop a 7-unit 5MW project connected to the ‘Wave Hub’ being built off Hayle in Cornwall.

    The 3-unit pilot project off Portugal is apparently working well, delivering 2.25MW, and they plan another 28 units this year.

    I can’t think of a downside to this technology, but I’m sure someone will come up with something.

    ‘Wave also has the potential to become one of the lowest cost forms of electricity generation, with opening costs now around half those of wind energy and a quarter those of solar PV. …. The worldwide market for wave power is estimated at £500bn.’

    Does sound promising this technology. Maybe they could place these machines amongst off-shore wind farms. Certainly a technology to watch.
