Sandians Participate in 46th Annual American Geophysical Union (AGU) Conference

Fifty-six Sandians from ten Centers joined more than 22,000 geoscience professionals, students, and academics at the December AGU Fall Meeting. Sandia staff chaired multiple technical sessions and gave dozens of presentations on topics ranging from improved climate models to performance models for underground waste storage to 3D printing and digital rock physics. Marianne Walck (Director [...]

Sandians Win ‘Best Paper’ Award at Photovoltaic Conference in Japan

A research team that included Sandians Clifford Hansen and Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) and Katherine Klise (in Sandia’s Geotechnology and Engineering Dept.) received a Best Paper Award for their work “Photovoltaic System Model Calibration Using Monitored System Data,” presented at the 6th World Conference on Photovoltaic Energy Conversion (WCPEC) [...]

Sandia Research on PV Arc-Fault Detection Submitted for US Patent

Different types of parallel arc-faults on the DC side of a PV array. Sandia National Laboratories/Tigo Energy researchers recently submitted an application for a US patent related to research on arc-fault detection and circuit interruption in solar photovoltaic (PV) systems. Sandia’s patent-pending methods, filed as Identifying an Arc-Fault Type in Photovoltaic Arrays, allow [...]

Linde, Sandia Partnership Looks to Expand Hydrogen Fueling Network

Sandia and industrial gas giant Linde LLC have signed an umbrella cooperative R&D agreement (CRADA) that is expected to accelerate the development of low-carbon energy and industrial technologies, beginning with hydrogen and fuel cells. On December 10, 2014, Linde opened the first-ever, fully certified commercial hydrogen fueling station near Sacramento with support from the California [...]

Storing Hydrogen Underground Could Boost Transportation, Energy Security

Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia study sponsored by the DOE Fuel Cell Technologies Office. Geologic storage of hydrogen gas could make it possible to produce and distribute large quantities of [...]

Predicting Pressure-Dependent Combustion Chemical Reactions

The Combustion Research Facility (CRF) at Sandia’s Livermore, California, site. Researchers at Sandia and Argonne national laboratories have demonstrated, for the first time, a method to successfully predict pressure-dependent chemical reaction rates—an important breakthrough in combus­tion and atmospheric chemistry that is expected to benefit auto and engine manufacturers, oil and gas utilities, and [...]

CFD-Populated Empirical Turbine Wake Model

The DTOcean team is developing a fast-running, easy to use current-energy capture (CEC) array spacing tool that considers tidal array performance vs efficiency. In support of this effort, Sandia has been assisting in developing the device wake modeling submodule that determines a tidal turbine’s wake properties (i.e., wake growth and dissipation). Initial efforts were focused on [...]
