Hydrokinetic energy company Minesto will soon begin a new round of testing with its "Deep Green" technology, HydroWorld.com has learned.
Minesto, which was awarded a Crown Estate license for testing in Northern Ireland's Strangford Lough in December 2011, will build on previous successes with the installation of a 1:4 test unit.
The company says it has already completed tests with a 1:10 unit, and based on the results of the quarter-scale unit, a commercial one could become a reality within the next few years.
Minesto describes the "Deep Green" system as an "underwater kite, comprised of a wing and a turbine which is secured to the seabed with a tether." The unit then "moves in a fast 8-shaped path in the tidal and ocean current".
The project is one of many hydrokinetic projects currently being developed in the United Kingdom as part of the European Union's renewable energy goal, which says 20% of the EU's power should come from green sources by 2020.
"Deep Green expands the total potential for marine energy considerably," says Minesto Chief Executive Officer Anders Jansson. "Marine energy is seen as increasingly strategically important in many countries, and especially in the United Kingdom."
