Wave power exceeds expectations
A wave power developer has said tests of a device off Scotland’s coast exceeded expectations.
US-based Ocean Power Technologies (OPT), which also has offices in Warwick, Warwickshire, deployed the machine from Invergordon, Easter Ross. The trials of the PB150 PowerBuoy required the consent of the Scottish government.
OPT has also been developing wave energy devices for powering US Navy and Marine Corps bases. OPT said it had successfully deployed the PB150 PowerBuoy off the coast of Scotland on 15 April 2011. It said initial reported power levels for the system had outperformed expectations.
OPT added: “The company believes the capacity factor represented by these results exceeded that experienced by most other renewable sources.” Source BBC
Back in October 2010, Ocean Power Magazine reported:
Ocean Power Technologies, Inc. has completed the first-ever grid connection of a wave energy device in the United States at the Marine Corps Base Hawaii (“MCBH”), in conjunction with the US Navy. This connection demonstrates the ability of OPT’s PowerBuoy(R) systems to produce utility-grade, renewable energy that can be transmitted to the grid in a manner fully compliant with national and international standards.
The PB40 PowerBuoy is part of OPT’s ongoing program with the US Navy to develop and test the Company’s PowerBuoy wave energy technology.

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
Wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave power generation is not currently a widely employed commercial technology although there have been attempts at using it since at least 1890. In 2008, the first experimental wave farm was opened in Portugal, at the Aguçadoura Wave Park.
The realistically usable worldwide resource has been estimated to be greater than 2 TW.Locations with the most potential for wave power include the western seaboard of Europe, the northern coast of the UK, and the Pacific coastlines of North and South America, Southern Africa, Australia, and New Zealand. The north and south temperate zones have the best sites for capturing wave power.
