VerdErg Renewable Energy Ltd has designed the Venturi-Enhanced Turbine Technology (VETT), a unique patented technology which uses venturi principles to concentrate the hydraulic energy of a large, low head flow into a smaller, high head secondary flow suitable for efficient conversion into electrical energy. VETT’s simple, versatile design can function in a range of flow conditions in rivers, marine and estuarine locations and is scale-able from a few kW to multi-GW installations.
