Tidal power comes in two main forms;

  • Tidal Range, where a large dam traps water when the tide comes in and let's it out through generating machines (an example is the UK's Severn Barrage, described here); and
  • Tidal Stream, where the generating machines take power from moving water as the tides ebb and flow.

Pulse Tidal is a Tidal Stream company. Tidal Stream power has much less impact on the environment than Tidal Range because the devices do not block the water flow, so mud flats and other areas which rely on regular flushing by the tide are not affected.

Tidal Stream power is often confused with wave power - wave power devices generally sit on the ocean surface, extracting power from the rolling motion of the waves, where-as tidal stream devices are mostly submerged and extract power from the currents caused by the ebb and flood of the tides.

Tidal streams are entirely predictable many years in advance. This means that the electricity produced by tidal power farms is completely dependable, allowing operators...
