How the Technology Works
Orbital Marine Power’s O2, the world’s most powerful tidal turbine, commenced grid connected power generation at the European Marine Energy Centre (EMEC) in Orkney in July, 2021. The innovative, floating turbine is anchored in the Fall of Warness where a subsea cable connects the 2MW offshore unit to the local onshore electricity network.
Orbital’s unique floating platform is moored via anchors in powerful tidal stream or river currents. Underwater rotors capture the dense flowing energy.
Manufactured and launched in Dundee earlier in the year before being towed up to Orkney, the O2 is Orbital’s first commercial turbine and represents the culmination of more than 15 years of world leading product development in the UK. The 74m long turbine is expected to operate in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes with clean, predictable power from the fast-flowing waters. In a further ground-breaking element of the project, the O2 is to provide power to EMEC’s onshore electrolyser to generate green hydrogen that will be used to demonstrate decarbonisation of wider energy requirements.
