Introduction

This page is about energy generation using waves and tides.

The technology

Wave

The Pelamis Wave Energy Converter is a semi-submerged, articulated structure composed of cylindrical sections linked by hinged joints. The wave-induced motion of these joints is resisted by hydraulic rams, which pump high-pressure fluid through hydraulic motors via smoothing accumulators. The hydraulic motors drive electrical generators to produce electricity. Power from all the joints is fed down a single umbilical cable to a junction on the sea bed. Several devices can be connected together and linked to shore through a single seabed cable.

Tidal

Specific plans

In the UK, The Crown Estates has helped establish test and demonstration facilities for wave and tidal energy devices off Orkney and Cornwall. It has published plans including a map for 6 wave and 5 tidal energy schemes near Orkney totalling 1.6GW.
