Investment boosts wave and tidal
Mar 14, 2007 International Power Engineer
Scotland has increased its funding for wave and tidal
power by £5m to meet demand, bringing total investment
in the sector up to £13m.
The money will be shared out between nine projects
aimed at developing new or improving existing marine
power technology, mostly at the European Marine Energy
Centre (EMEC) in Orkney, where the world's biggest
commercial wave power farm is now being developed.
Over £4m in funding will go to a development project
that involves arranging four units of the 750kW Pelamis
wave device into a single wave energy array, giving
a total output of 3MW. A world first was achieved
when Pelamis, a marine energy converter developed
by Edinburgh-based Ocean Power Delivery, generated
electricity for the National Grid from EMEC's wave
test site off Billia Croo, Stromness. A second test
site for tidal devices off the island of Eday is nearing
completion. Pelamis is currently under test in Portugal.
In December 2006, Irish energy technology company
OpenHydro successfully completed the installation
of the first tidal turbine at EMEC.
EMEC is the first centre of its kind to be created
anywhere in the world and offers developers internationally
the opportunity to test prototype devices in unrivalled
wave and tidal conditions with comprehensive round-the-clock
monitoring. The company was established to help the
evolution of marine energy devices from the prototype
stage into the commercial market place.
Generators are connected to the National Grid via
seabed cables running from open-water test berths.
Testing takes place in a wide range of sea and weather
Nicol Stephen, Deputy First Minister, said, "Scotland
has the potential to generate a quarter of Europe's
marine energy and kick-starting the sector is vital
if we are to create a significant industry based in
Scotland and meet our long-term renewables targets."
