The Race Rocks Tidal Energy Project

In October 2008 Clean Current™

re-installed its tidal turbine generator  to replace 2 diesel generators at Race Rocks Ecological Reserve. Testing has been completed at tidal currents greater than 7 knots. The project has been supported by EnCana Corporation, Pearson College and Sustainable Development Technology Canada.

Development of Tidal Energy Markets in the World .
The market for deep water tidal turbine generators is an educated guess because few countries have completed resource assessments. Based on the recent assessments done in Europe and Canada together with rough estimates of tidal sites in other parts of the world, Clean Current estimates that market for equipment is at least 67,000 MW. At US$2000-US$ 3000 per kW the equipment market has a potential of reaching US$200 billion. When fully developed, these tidal energy farms would deliver about 138 billion kilowatt hours of electricity each year. At 20 US cents per kW hour, the annual market for electricity would be US$27.6 billion.

The key to developing this market potential is a simple, efficient, long life, low cost technology that is relatively environmentally benign. Clean Current's  technology meets these criteria.

Clean Current Power Systems Incorporated

Clean Current Power Systems Incorporated is a private Canadian company that develops technology to extract electricity from ocean tidal currents. Clean Current designs and licenses tidal energy technology that converts the kinetic energy of tidal currents into electricity with unprecedented efficiency. Features of the technology include high efficiency, simple design with one moving part, no drive shaft or gearbox, no surface structure, long service life, low capital cost, low maintenance costs and minimal environmental disturbance. Clean Current is a tidal energy success story.

Alstom Hydro has signed a licensing cooperation agreement with Clean Current Power Systems Incorporated.

The terms of the agreement between Alstom Hydro and Clean Current Power Systems Incorporated include an exclusive worldwide license for ocean and tidal stream applications for Clean Current’s patented technology. The agreement also includes provisions for continued close cooperation between both parties in order to further develop technology, deploy demonstrator units and subsequently position Alstom Hydro as both an equipment and turnkey provider for tidal stream farms. Alstom plans to commercialise its first tidal stream products by 2012. >>read more

Clean Current and the Environment
Clean Current's technology has unique features that make it extremely friendly to the environment. The turbine generator is entirely below the surface of the water and  has one moving part. The novel duct design of the unit ensures that there are no exposed blade tips and provides a large hole in the middle of the unit (about 5 metres diameter in commercial scale unit) through which fish and sea mammals can pass in the highly unlikely event that they are to enter the inlet duct area.
