Energy Projects to Develop Technologies for Reliable and Cost-Effective Marine Energy

Sandia will team on two of six recently announced projects to develop technologies for generating reliable and cost-effective electricity from U.S. water resources. One project will investigate the design of high-deflection turbine blades and the other aims to improve and optimize Oscilla Power, Inc.’s linear hybrid drivetrain technology. Both address technology development challenges for marine [...]

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 [...]

Technology Development

Sandia's Water Power Technologies program develops innovative technological solutions for  marine hydrokinetic (MHK) devices. Before MHK technologies can successfully compete in the energy market, developers must increase device power performance and reliability, thereby reducing the levelized cost of energy.  Through applied research and modeling efforts, we provide industry with tools to create better [...]

Experiment for Improved Modeling of Trailing-Edge Shedding Noise

Baseline 12.5% thick uncambered NACA 65 series foil (top) and 18% thick cambered MHK foil (bottom). To better understand the flow physics associated with shedding from marine hydrokinetic (MHK) foils, Sandia conducted an experimental study in the Penn State University Applied Research Laboratory. Our team tested MHK foil shapes in a free-stream flow [...]

Sandia Funded to Model Power Pods for Utility-Scale Wave-Energy Converter

Planning an open-water test facility for utility-scale wave-energy converters (WECs) within the US requires a multifaceted approach. Concerns regarding the siting and permitting, the environmental interactions, the device performance, and the cost of the facility must all be simultaneously addressed. The DOE has started to investigate a utility-scale WEC testing facility with the recent awards [...]
