PREDICTS 1: Results of Module-Level Power Electronics Accelerated Testing

A project team led by Sandia National Labs, with partners at Arizona State and TUV Rheinland, has applied a suite of accelerated life tests to module-level power electronics (MLPE) devices to predict their reliability and durability in the field. A subset of the DOE’s Physics of Reliability: Evaluating Design Insights for Component Technologies in Solar (PREDICTS), this [...]

New report highlights key composite testing trends for more reliable and lower cost wind blade designs

Sandia National Laboratories recently published "Analysis of SNL/MSU/DOE Fatigue Database Trends for Wind Turbine Blade Materials, 2010-2015" by researchers at Montana State University (MSU), a long-time academic research partner. Since 1989, Sandia has collaborated with MSU to test and report key data and trends related to fiber-reinforced polymers (composites) and other materials used to construct wind turbine [...]

Sandia Labs high-flux solar simulator with one-of-a-kind capability

The High-Flux Solar Simulator with automated sample handling and exposure system (ASHES) is a one-of-a-kind capability which can be used 24/7 with metal-halide lamps.  ASHES provides accelerated lifetime aging tests for materials under high-temperature/high-flux conditions.  A robotic sample-handling system can be used to move multiple coupons automatically into and out of the concentrated flux sequentially to [...]

Sandia defines solar variability zones

Sandia Labs has defined solar variability zones by modeling solar variability across the country using a combination of ground measured and satellite derived solar irradiance measurements. The zones represent the magnitude of high-frequency (sub-minute) solar variability—changes in available sunlight—at each location. Photovoltaic (PV) installations in locations with higher solar variability can, all else being equal, [...]

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 [...]

Sandia Develops Stochastic Production Cost Model Simulator for Electric Power Systems

Sandia has developed a software toolkit that uses stochastic programming to perform power system production cost model simulations. Named PRESCIENT, the software produces probabilistic forecasts automatically from deterministic historical forecasts for load, solar, and/or wind power production and their respective actuals, using a technology known as epi-splines. An example of a probablistic solar forecast [...]

New CREW Database Receives First Set of Data

The CREW public benchmark represents analysis of US wind fleet performance based on aggregated fleet reliability data. Sandia’s Continuous Reliability Enhancement for Wind (CREW) project has received its first large set of data, which reassessed its data-collection efforts to target wind-farm owner/operators that have in-house reliability data collection tools. After a lengthy negotiation [...]

Aerodynamic Wind-Turbine Blade Design for the National Rotor Testbed

The NRT blade shape as viewed from the tip and at an elevation angle of 30° above the suction surface. Sandia has designed a new wind-turbine blade for the National Rotor Testbed (NRT) project and for future experiments at the Scaled Wind Farm Technology (SWiFT) facility with a specific focus on scaled wakes. [...]

Sandia Research to Be Featured on Upcoming Cover of Journal of Physical Chemistry B

Several Sandia Joint BioEnergy Institute (JBEI) researchers, in collaboration with others in Kentucky and India, have published, “Theoretical insights into the role of water in the dissolution of cellulose using IL/water mixed solvent systems,” which the editors selected for Journal of Physical Chemistry B’s Nov. 12th issue cover. The continued reliance of the global transportation energy [...]

JBEI Featured in Chemical & Engineering News Cover Article

Researchers at the Joint BioEnergy Institute (JBEI) are working to transform biomass into energy-rich fuel molecules. Headquartered in Emeryville, California, the Joint BioEnergy Institute (JBEI) is now a member of the elite “100/ 500 Club,” having filed its 100th patent application and published its 500th scientific paper.
