Alstom Hydro licenses tidal technology from Clean Current Power

Hydro equipment manufacturer Alstom Hydro has signed a technology licensing agreement with Clean Current Power Systems Inc., a Canadian developer of hydrokinetic tidal energy technology.

Alstom Hydro, a joint venture of Alstom and Bouygues of France, said May 26, 2009, the agreement includes an exclusive worldwide license for ocean and tidal stream applications for Clean Current’s patented technology.

Clean Current’s tidal energy technology consists of an underwater horizontal-axis ducted turbine with a direct drive variable-speed permanent magnet generator. The turbine generator is equally efficient in both directions to take advantage of two-way tidal currents, the companies said.

The agreement also calls for Alstom Hydro and Clean Current to cooperate to further develop technology, deploy demonstration units, and position Alstom Hydro as an equipment and turnkey provider for tidal stream farms.

Alstom said it plans to commercialize its first tidal stream products by 2012, but did not offer additional details.

British Columbia-based Clean Current is one of several companies previously named to pursue tidal demonstration projects in the Minas Passage area of Nova Scotia’s Bay of Fundy. (HydroWorld 5/6/09)
