An experimental floating tidal power plant has been launched at the Sevmash Plant in the city of Severodvinsk, in Russia’s Arkhangelsk region.
Developed by Hydro WGC, the 33 m long, 10 m wide plant is equipped with an experimental 1,500 kW orthogonal hydraulic turbine.
The orthogonal turbine is uni-directional and its rotation does not change with the rise and fall of the tide, providing significant efficiency gains of up to 60-70%.
The unique design of the hydraulic unit also reduces construction cost by 30-40%, the developers say.
The unit will be towed to the Barents Sea shore and installed near the Kislogubskaya Tidal Power Plant, an existing test site.
