Dedication of University of Maine’s W2 Ocean Engineering Laboratory

The University of Maine officially opened its combined wind and wave (W2) experimental facility on November 23, 2015. The University of Maine partnered with Diana Bull (Sandia), Amy Robertson (NREL), and Richard Kimball (Maine Maritime Academy) in the design and development of this facility. W2 not only will allow for testing of offshore structures in [...]

Investigations on Anti-biofouling Zwitterionic Coatings for MHK Is Now in Press

Sandia’s Marine Hydrokinetic (MHK) Advanced Materials program has a new publication on the antifouling efficacy of zwiterionic coatings. These polymeric coatings contain no metal and have both positive and negative chemical charges as part of their molecular structure. The coating was investigated in response to finding environmentally friendly materials for MHK devices by the Sandia-UNM [...]

Natural Energy Laboratory of Hawaii Authority Partners with Sandia to Install Aquion EES Demo

The Natural Energy Laboratory of Hawaii Authority (NELHA) and Sandia have signed an MOU to implement electrical energy storage systems (ESSs) in renewable-energy projects at their Hawaii Ocean Science and Technology (HOST) Park. Aquion Energy battery module installed at NELHA. Hawaii’s innovative green economic development park plays a significant role in Hawaii’s growth [...]

Wave-Energy/-Device Modeling: Developing A 1:17 Scaled Model

Many theoretical studies show that additional energy can be captured through control of the power-conversion chains (PCCs) of resonant wave-energy converter (WEC) devices. The numerical models employed in these studies are, however, idealized to varying degrees. The objective of the Resilient Nonlinear Controls (RNLC) project is to validate the extent to which control strategies, given [...]

New Small Business Voucher Pilot Opens

The highly anticipated Department of Energy (DOE) Small Business Vouchers (SBV) pilot opens for business today. Through the pilot, small businesses can apply to access the Department’s world-class facilities and an enterprise of more than 10,000 leading scientists and engineers at the National Renewable Energy Laboratory and Lawrence Berkeley, Oak Ridge, Pacific Northwest, and Sandia national laboratories. [...]

Sandia Modifies Delft3D Turbine Model

Delft3D is a state-of-the-art, open-source hydrodynamics software suite capable of modeling hydrodynam­ics, sediment transport, and water quality in rivers, lakes, estuaries, and coastal environments. Delft3D was developed by the Dutch company, Deltares. Because it is actively developed and maintained and because it is held in high regard by researchers and practitioners alike, Sandia is developing [...]

Australian Renewable-Energy Official Visits Sandia

Louise Vickery, General Manager, Renewable Futures at the Australian Renewable Energy Agency (ARENA). At the end of June, Louise Vickery, General Manager, Renewable Futures at the Australian Renewable Energy Agency (ARENA) visited Sandia. ARENA manages the Australian government’s commitment to improve the competitiveness of renewable energy technologies and to increase Australia’s renewable energy [...]
