  • Summary:
    A Spanish research group has developed a turbine that can work continuously with bidirectional flow. It is suitable for recovering wave energy and comprises two crowns of blades integrated in the same rotor, so that one of them produces power while the other performs an aerodynamic blockage of the flow. The device solves many disadvantages of current systems, providing better and more stable performance. Renewable energy companies are sought to develop applications under license agreements.
  • Description:
    Many studies have found that wave energy has great potential, as well as being a source of renewable energy. Therefore, a great effort is being made to research and develop possible technologies that allow us to make the most of the oscillating nature of the waves.

    Researchers from a Spanish university have developed a new high efficiency turbine suitable to exploit wave energy, which can continuously work with alternative bidirectional flows.

    Contrary to the systems currently used, the present development provides better and more stable performances. Moreover, the system turns to be simpler and compact due to the unique turbine installed.

    The turbine for bidirectional flow comprises two crowns of blades integrated in the same rotor, so that one of them produces power while the other performs an aerodynamic blockage of the flow.

    The main components of this system are:

    - Two crowns of blades integrated in the same rotor. The blades of each crown are oriented in a specular manner, so that each of them has the leading edge facing one of the two directions of flow respectively.
    - An outer duct that contains the turbine.
    - A nucleus that deflects the flow.
    - An internal wall that sets two flow channels, where one flow is blocked and the other produces power.

    The researchers would like to reach license agreements with companies that work in those sectors where turbines are designed, manufactured, produced or used, such as in the machinery and mechanical equipment or energy and water fields, and more specifically to any system or process where there is a type of bidirectional flow one wants to extract energy from, such as the renewable energy devices known as OWC (Oscillating Water Column).
