US Energy Department Awards $4.5 Million for Wind Power
The Energy Department announced $4.5 million for four projects to help increase deployment of innovative wind power technologies by optimizing the operation, boosting efficiency, and improving the environmental performance of wind energy systems.
Biodiversity Research Institute of Gorham, Maine, will receive $1.1 million to develop a stereo-optic camera system to detect and document bird and bat flight behavior in the vicinity of wind turbines to help researchers better understand potential environmental impacts of wind turbines.
Texas Tech University in Lubbock, Texas, will receive $1.4 million to develop a first-of-its-kind, radar-based prototype to measure the flow of wind through wind farms, which will increase data availability and lead to improved modeling.
The University of North Carolina at Charlotte will receive $500,000 to design and build a 30-kilowatt multistage magnetic gearbox, which will be validated for reliability, efficiency, and its potential to operate more quietly than currently available generators.
The University of Nebraska-Lincoln will receive $1.5 million to develop an online health monitoring system that uses the electric current signals produced by a turbineís generator to track the generatorís performance and help determine when it needs to be repaired. This technology could reduce operating costs by decreasing unscheduled downtime due to unplanned maintenance.
ClassNK Focuses on Renewables
ClassNK (Tokyo, Japan) has established a new Renewable Energy Department to oversee activities related to renewable energy, including audits and certification of new technologies.
Activities previously carried out by the ClassNK Wind Turbine Division will now be carried out by the Renewable Energy Department.
ORPC Completes RivGen Demo in Kvichak River
ORPC (Portland, Maine) has concluded its RivGen Power System demonstration project in the Kvichak River at the remote river village of Igiugig, Alaska. ORPCís RivGen Power System is a 25-kilowatt system designed to reduce and stabilize the cost of power in remote communities located near rivers and tidal estuaries that currently use diesel fuel for power generation.
The RivGen System was installed with local equipment, provided significant power for the microgrid, and coexisted well with the fish habitat of the Kvichak River.
Other project highlights include: several successful deployments and retrievals using only the deviceís ballasting system, thereby proving the self-deploying/retrieval features of RivGen; remote operation and adjustment of the system via network by ORPC engineers; delivery of the projected amount of power to the onshore station; and comprehensive environmental monitoring of the device that showed that the operating power system had no known negative impacts on fish and other aquatic life.
Haliade 150-6MW Turbine Produces its First Kilowatt-Hour
Alstom's (Levallois-Perret, France) next-generation Haliade 150-6MW offshore wind turbine off the Ostend coast at Belgiumís Belwind facility has produced its very first kilowatt-hour.
Tests will continue to confirm how the machine behaves within a maritime setting, and to fine-tune operation and maintenance procedures. The Haliade should obtain final certification in the last quarter of 2014.
Eurostars Awards €750,000 to Minesto, Atlantis Resources
Minesto (Västra Frölunda, Sweden) and Atlantis Resources Ltd. (Singapore) have been awarded €750,000 from the Eurostars Program, funded by the European Union. The funds will be used to reduce the cost of tidal power plants by creating cost-effective, high-reliability tidal turbine blades and wings of composite materials. The total project value is €1.5 million, of which €750,000 is covered by Eurostars. The project will be a collaboration between Minesto (Sea Technology, April 2014) and Atlantis. Collaboration between different tidal energy developers is essential to speed up time-to-market for power plants that could make an impact on the global renewable energy arena.
Key components of Minestoís and Atlantisís tidal energy converters will be jointly developed.
Minestoís Deep Green can produce cost-effective electricity from both low-flow tidal and ocean currents. In this project, Minesto will further develop the wing for Deep Green to harness tidal flows of 1.2 to 2.5 meters per second.
Atlantisís flagship turbine, the AR1500, is a 1.5-megawatt horizontal axis machine. The project will involve Atlantis completing material testing to understand the nature of the complex composite materials used in blade manufacture; using computational fluid dynamics and finite element analysis for detailed blade design; exploring the optimization of methodologies and techniques for production; and manufacturing, testing and certifying one turbine blade.
WavePOD Moves to IFAS for Further Development
The WavePOD prototype has moved to the Institute for Fluid Power Drives and Controls (IFAS) at Aachen University, Germany.
The WavePOD wave power offtake device is being developed by Bosch Rexroth (Lohr am Main, Germany) as part of a collaboration including some of Europeís leading wave energy developers, utilities and academic institutions. Its goal is to develop an industry-wide power take off that will generate electricity reliably and cost effectively at sea.
Laboratory testing will give data on how the WavePOD works in controlled conditions and will allow Bosch Rexroth to develop and refine the prototype prior to testing at sea next year.
The project will then put the WavePOD prototype through a program of installation, operation, maintenance and decommissioning in real wave conditions on Aquamarine Powerís (Edinburgh, Scotland) Oyster 800 machine in Orkney, Scotland, in 2016. If funding is secured, a quarter-scale prototype will be developed to be tested at sea on both Oyster 800 and Carnegie Wave Energyís (Fremantle, Australia) CETO technology at WaveHub in Cornwall.
