The EEL Tidal Energy Converter

An innovative solution

Energy conversion by an undulating membrane.

  • The EEL membrane optimizes energy transfer by coupling fluid flow with an undulating structure.
  • Operation: The membrane undulates under moving fluid pressure. This periodic motion is transformed into electricity by an electromechanical system.
  • Energy is converted along the whole length of the membrane surface.
  • A monitoring loop ensures optimized energy conversion in response to changes in flow conditions and power transmitted.
  • Worldwide patented technology.

A tidal machine with promising performance.

Technological advantages of the EEL Tidal Energy Converter.
  • High power production possible (5MW).
  • No Betz limit. Betz' law limits turbine energy conversion up to 59.3%.
  • No cavitation problems.
  • Undergoes low drag force.
  • Reduced dimension compared to captured power.
  • Machine adapts to flow velocity for optimized operation.
  • Energy is converted directly into electricity on the machine.
  • Low start up velocity (0.4 m/s).
  • Automatically orientates in accordance with current direction, thus capturing 100% of the current.
  • High density of units per area in harvest farm.
  • Installation near coasts possible, reducing transmission costs.
  • Many potential applications.

Prototype tested with industrial production scheduled for 2018.
