Lockheed Martin Supports
Ocean Power Technologies
Ocean Power Technologies will
collaborate with Lockheed Martin on its proposed commercial-scale wave
power generation project at Reedsport, Oregon.
Lockheed Martin will provide
design, manufacturing, system integration and supply chain management
expertise to enhance OPT's PowerBuoy technology. OPT said this builds
on previous work conducted by Lockheed Martin and OPT.
The collaboration follows a
US$2.4 million contract awarded by the US Department of Energy to OPT
as part of initiatives announced in September 2010 to promote the development
of renewable marine energy.
Construction of the Oregon
PB150 PowerBuoy's steel structure has been completed, and testing of the
advanced power take-off and control system is in process at OPT's production
facility in a test environment simulating the varying wave conditions
off the Oregon coast.
Assembly, systems integration,
and land testing of the PowerBuoy is planned to occur over the next several
months. It is intended to be the first of a proposed 10-buoy wave power
station with a peak generating capacity of 1.5 MW, equivalent to the power
needs of about 1,500 homes.
"OPT's engineering and
innovation efforts for the utility market are focused on improving power
conversion efficiency, reliability, manufacturability and lowering the
costs of marine operations and maintenance," said Charles F. Dunleavy,
chief executive officer of OPT.
"We will be rolling out
the PB150 PowerBuoy product, our latest utility market offering, over
the next few years and will also leverage this experience for the next
generation of the PowerBuoy, our 500 kW device that is currently under
"With the Department of
Energy's continued support and Lockheed Martin's expertise, the commercialization
of our technologies to harness wave power continues to make steady progress,"
said Mr Dunleavy.
In another development, Ocean
Power Technologies is working with a consortium of European companies
and institutions on a technology initiative to enhance the efficiency
of its patented PowerBuoy wave energy systems.
Under its "WavePort"
project, the new wave prediction model will assess the characteristics
of each incoming wave before it reaches the PowerBuoy wave power station,
providing more time for the electronic tuning capability to react. It
is expected this will significantly boost the power output of the PowerBuoy
and reduce cost per megawatt hour of energy produced, said the company.
Ocean Power Technologies has
a 2.2 million grant under the WavePort project from the European Union's
Seventh Framework Program for research and innovation.
