The US Department of Energy (DOE) and the Federal Aviation Administration (FAA) have placed a 700-mile-long, 40-mile wide stretch of airspace, north from Oliktok Point (the northernmost point of Alaska’s Prudhoe Bay) to about 400 miles short of the North Pole under Sandia’s stewardship. Oliktok Point is a base of operations for the Atmospheric Radiation Measurement (ARM) Climate Research Facility, a multi-platform scientific user facility with instruments at fixed and varying locations around the globe […]
As part of the Western Electricity Coordinating Council’s (WECC’s) Modeling and Validation Work Group, Sandia researcher Ryan Elliott (in Sandia’s Electric Power Systems Research Dept.) recently contributed to an update to WECC’s Central Station Photovoltaic Power Plant Model Validation Guideline.
The document provides photovoltaic (PV) plant owners and transmission planners with best practices for model validation of utility-scale PV systems connected to the transmission network. The procedures outlined in the document are designed to assist stakeholders […]
Large-eddy simulation (LES) of wind farms with wind-turbine parameterization is emerging as a powerful tool for improving existing wind farm performance and lowering maintenance costs—and assessing the potential sites for installing wind farms.
Sandia is working with the University of Minnesota (UMN) St. Anthony Falls Laboratory to document and prepare UMN’s offshore version of the Virtual Wind Simulator (VWiS) code for release. VWiS is a state-of-the-art LES code that is capable of simulating atmospheric turbulence interacting […]
Wind-turbine blades pose a unique set of inspection challenges: from very thick and attentive spar-cap structures to porous bond lines, varying core material, and a multitude of manufacturing defects of interest. The need for viable, accurate, nondestructive inspection (NDI) technology becomes more important as the cost per blade—and lost revenue from downtime—grows. Under its Blade Reliability Collaborative program, Sandia is quantitatively assessing the performance of a wide range of NDI methods that are currently deployed, […]
Offshore wind energy could potentially play a significant role in helping the nation establish a diversified energy-generation portfolio composed of clean, renewable resources. A current obstacle to offshore wind energy is that most projections put offshore wind farm operations and maintenance (O&M) costs between 2 to 5 times the current average O&M costs for onshore wind farms. One way in which those costs may be reduced is through a simple, yet effective structural health monitoring […]
This workshop, held June 9–11 in Santa Fe, explored physical and geochemical processes in shale controlled by diagenesis; nano-confinement and pore-scale coupled processes in shale; fracture and coupled processes of shale; and multi-scale, multi-physics behavior of shale. Please see the workshop website for the list of speakers, presentations, and the meeting agenda.
Shales at All Scales gathered 47 participants from many institutions.
Academia (University of Texas; Massachusetts Institute of Technology; Ohio State, Purdue, Stanford, and Texas A&M […]
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 Delft3D as a complementary replacement for the aging open-source-version of the Environmental Fluid Dynamics Code (EFDC), which was modified to include […]
Two Sandia research reports, “Structural Code Considerations of Solar Rooftop Installations” and “Empirically Derived Strength of Residential Roof Structure for Solar Installations,” have been featured recently in a number of solar trade outlets.
The reports detail rooftop structural analysis conducted by Sandia and funded by the US Department of Energy’s SunShot Initiative. Test results indicate that the actual load-bearing capacity for residential rooftop structural systems is several times higher than published values. These outcomes provide a […]
The DOE chose Sandia as one of five leads in a pilot that will give small, clean-energy companies access to national laboratory expertise and resources. Sandia will receive $2.75M of DOE’s $20M investment to launch the voucher pilot for small business assistance and collaborative research. “Our pilot, which we’ve named Tech Assist Green (TAG), unites the three NNSA labs—Sandia, Los Alamos and Lawrence Livermore—to provide a broad array of unique assets from the national lab […]

Crawford Elliott and his PhD student Laura Zaunbrecher from Georgia State University, have been examining the adsorption mechanisms of metal cations onto soils and sediments. This effort is especially important for the environmental treatment of chemical and radioactive contaminants, including the fission product cesium-137—which is […]
Carlos Michelen (in Sandia’s Water Power Technologies Dept.) and a team of National Renewable Energy Laboratory (NREL) researchers (Michael Lawson, Braulio Garzon, Fabian Wendt, and Yi-Hsiang Yu) won the Offshore Mechanics and Arctic Engineering (OMAE) 2015 Hydraulic Modeling Competition during the 34th ASME International Conference on Ocean, Offshore, and Arctic Engineering in St. Johns, Newfoundland, Canada, in June. The NREL and Sandia team entered the competition and modeled the experimental device (described below) using both
Sandia researchers are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles.
This month, engineers lifted Sandia’s continuously recirculating falling-particle receiver to the top of the tower at the National Solar Thermal Test Facility (NSTTF), marking the start of first-of-its-kind testing that will continue through 2015. The Sandia-developed falling-particle receiver drops sand-like ceramic particles through the NSTTF’s concentrated sunlight beam, capturing and […]
