However, it is committed to delivering power to the European Marine Energy Center’s onshore electrolyzer to generate green hydrogen. The entire contraption is anchored to the seafloor at four points and has a 1-MW turbine nacelle on either side of its 242-ft (74-m)-long hull, with 32-ft (10-m) blades capturing tidal energy over an area of more than 600 m2.Īccording to Orbital, the O2 turbine has an operational lifespan of approximately 15 years and can meet the annual electricity needs of roughly 2,000 homes.
The O2 turbine is connected to the local onshore electricity network via an undersea cable. In July, Orbital Marine Power announced that the O2 has officially started grid-connected power generation at the European Marine Energy Center in Orkney. Two days later, the 2MW tidal turbine arrived in the Orkney Islands, an archipelago of Scotland’s north-eastern coast and home to some of the strongest tidal currents in the world. On April 22, Scottish company Orbital Marine Power launched “the world’s most powerful tidal turbine,” the Orbital O2, from the Port of Dundee.
While it’s not yet widely used, tidal energy has potential for future electricity generation because waves are more predictable than the sun and the wind.Īmong renewable energy sources, tidal power has suffered from high cost and limited availability of sites with sufficiently tidal currents or flow velocities, thus limiting its total availability. Tidal power is harnessed by converting energy from tides into electricity using various methods.
