The Scottish Executive awarded the equivalent of more than $25 million in grants in late February to support a variety of wave and tidal energy projects. Most of the projects involve test installations at the European Marine Energy Centre (EMEC) in Orkney, which aims to be a world-leader test facility for wave and tidal energy projects. Among the wave energy awardees are CRE Energy, Ltd., which plans to deploy an array of four 750-kilowatt cylindrical Pelamis wave energy converters, developed by Ocean Power Delivery, Ltd. (OPD); AWS Ocean Energy, which will install its 500-kilowatt Archimedes Wave Swing; Ocean Power Technology (OPT), which will install its 150-kilowatt PowerBuoy; Aquamarine Power Ltd., which will deploy its Oyster, a near-shore device that is mounted on the seabed; and Wavegen, which will install a new turbine in its oscillating water column system on the isle of Islay.

The tidal energy awardees include ScotRenewables Ltd., which will install its 1.2-megawatt floating device with dual undersea rotors; OpenHydro Group Ltd., which will deploy a 750-kilowatt turbine on the sea floor; Tidal Generation Ltd., which will also mount its 1-megawatt turbines on the seabed, and CleanTechCom Ltd., an affiliate of Woodshed Technologies, which will install siphon pipes through a causeway on Orkney to take advantage of the tidal differences on either side of the barrier.
