Tidal Sails

Clean energy by sailing the tide

About Tidal Sails

Tidal Sails AS, an independent, privately held closed corporation based in Haugesund, Norway brings to market a ground breaking technology to extract kinetic energy from slow moving currents, by combining the ancient principles of ocean sailing with state of the art alpine ropeway technology, to generate low cost electricity.
Tidal Sails has carried out a range of theoretical and numerical studies over the years. These have been validated by several prototypes and test rigs.

Competitive advantages

Energy from slow streams

Down to 1,5 m/s – this means the majority of streams. Very few can match this

Cost efficient and Low Weight

Extreme low weight to output ratio with ability to harvest energy from a large cross section of the currents.

No visual pollution

Our technology operates on 15meters depth which means no visual pollution

Operation & Maintenance 

Direct Drive Permanent Magnet Generators, Self-Cleaning Sails and Water Lubricated Sail Bearings.

Technological Advantage

Unrivalled exposed area in the energy stream is essential in slow currents.

Environmental Impact

Slow moving sails 15meter beneath shipping lanes, are assumed harmless to diving birds, fish and mammals.

Maritime traffic

The facility is 15 meters deep in the ocean, this means no disturbance to maritime traffic on the surface

No harm to sea life

Our slow sails do not harm sea life unlike traditional turbine solutions offered by our competitors
