Eco2 and its shareholders are the main funder and driving force behind Tidal Energy Ltd (TEL), an innovative tidal stream technology company.

TEL has successfully installed a single DeltaStream unit off the coast of Pembrokeshire at Ramsey Sound. The project will demonstrate the capability of DeltaStream as a tidal stream generator and will provide evidence on how the device interacts with the environment around it.

A DeltaStream unit includes the following features:

  • A triangular steel main base frame with ‘Rock Feet’ to secure the device to the seabed. By providing a gravity foundation for three nacelles, this system reduces the high installation and maintenance costs traditionally associated with marine renewable technology.
  • An independent horizontal axis water turbine generator in each nacelle, supported on a tower at the apexes of the triangular main base.
  • An automated hydraulic yaw mechanism for each nacelle which controls the orientation of the water turbine generators in relation to the direction of the tidal flow.
  • Connection of the device to shore with an export submarine power cable, and power conditioning equipment for grid connection located onshore.
