Off the coast of Orkney, in northern Scotland, sits a giant orange platform that is floating on the waves. Underneath it are two huge turbines, turned by the tides. This is the Orbital O2, a floating tidal platform with two turbines and one of the world’s most powerful tidal-energy systems. According to Orbital Marine Power, the O2 has been generating grid-connected power at its Fall of Warness site in Orkney since July 2021, after setting off from Dundee that April.
