River Turbines

General Description /Main Features

Clean Current has developed a family of turbines ideally suited to the specific environment found in rivers. This technology, adapted from Clean Current’s extensive experience gained in tidal turbines, uses the same proprietary generator and bearing technology and combines this with specific blade and duct modifications. The result is a simple, yet robust product designed to operate with minimal maintenance over a 25 year period. The product family has been developed to suit different river depths ranging up to 15.0+ metres. These units produce a given rated power for a given rated current speed as shown in the Table below.

This family of river in-stream turbines provides the customer with the following benefits:

  • Simplified design enhances reliability
  • Proprietary coatings and application methodologies
  • Fault tolerant generator specifically designed for the marine environment
  • Demonstrated superior turbine performance
  • Totally submerged, ducted structure
  • Easily deployed and retrieved, even in remote locations
  • Autonomous operation and remote performance monitoring
  • Ideally suited for remote locations as it is easily integrated with other renewable energy sources and existing diesel generation
