Scottish Renewables hail Orbital O2 as worthy of ‘global attention’ over net-zero future push

Scotland’s renewables trade body have described the launched of the world’s most powerful tidal turbine as a ‘beacon’ of energy innovation.

Scottish Renewables also insisted the technological achievement was worth of global recognition, not least as world leaders gathered virtually for a climate summit arranged by US President Joe Biden.

There he pledged the US would more than half its carbon emissions by 2030 while UK Prime Minister Boris Johnson reiterated Britain’s bid to make cuts of 78% by 2035.

Leaders also hailed renewables as the way to achieve much of this, and in creating new jobs to support their economies.

Orbital Marine Power unveiled its latest contribution today with the ambitious, groundbreaking project that has already supported almost 100 jobs along the way, as well as stimulating the supply chain right across the UK.

Once hooked up, the Orbital O2 will deliver enough predicable clean energy to power the equivalent of 2000 homes.

Ben Miller, Senior Policy Manager at Scottish Renewables, said: “The launch of the O2 turbine today in Dundee deserves global attention this Earth Day, as coastal nations seek out the marine technologies that can deliver our net-zero future.

“Orbital should be very proud of this contribution to engineering and the UK supply chain, and we look forward to its operation in Orkney, a fitting home for one of Scotland’s beacons of energy innovation.”


  • The O2 turbine has a 74m long hull structure with twin 1MW power generating nacelles at the end of retractable leg structures designed to give low-cost access to all major components for through life servicing.
  • 10m blades give the O2 more than 600m2 of swept area to capture flowing tidal energy.
  • The floating structure is held on station with a four-point mooring system where each mooring chain has the capacity to lift over 50 double decker buses.
  • The O2 has been designed so that installation of the turbine, and all its associated moorings, can be carried out by low-cost work vessels and servicing can be carried out by RIB vessels – minimising downtime and lowering construction and operational costs.
  • Electricity is transferred from the turbine via a dynamic cable to the seabed and a static cable along the seabed to the local onshore electricity network.

It was supported through funding from the European Union’s Horizon 2020 research and innovation programme under the FloTEC project and the European Regional Development Fund through the Interreg North West Europe Programme under the ITEG project.

The project also received support under the framework of the OCEANERA-NET COFUND project and co-funding by the European Union’s Horizon2020 research and innovation programme.

The Scottish Government also supported it under the Saltire Tidal Energy Challenge Fund while a £7m commercial debenture from the Abundance Investment platform also enabled the project.
