Launched in April in Scotland, the 2 MW Orbital O2 tidal power plant has begun generating electricity that is fed into the local terrestrial grid via a submarine cable.
The 680-ton structure, 74 meters long, was brought out to sea by Osprey Shipping. Orbital O2 is expected to operate over the next 15 years. The power plant is held in place by a four-point mooring system. The power plant floats on the surface, and the rotors with turbines are on supports immersed in water, as shown in the video:
The plant is said to generate enough electricity “to meet the needs of about 2,000 homes in the UK and offset approximately 2,200 tonnes of CO2 production per year.”
Going forward, O2 will power the EMEC onshore green hydrogen cell, which will be used to demonstrate the ability to decarbonize broader energy needs, according to project implementer Orbital Marine Power.
