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

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 other industries that employ combustion models. A paper describing the work, performed […]

Consortium for Advanced Simulation of Light-Water Reactors To Receive Up To $121.5M Over Five Years

The Department of Energy approved the Consortium for Advanced Simulation of Light-Water Reactors’ (CASL’s) “Phase 2” renewal to develop advanced computing capabilities that serve as a virtual version of existing, operating nuclear reactors—to enable nuclear energy to continue to provide dependable, afford­able energy to America while advancing innovative research in an energy source central to […]

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 […]

Floating Oscillating Water Column Reference Model Completed

The DOE-supported Reference Model Project was developed to provide publicly available technical and economic benchmarks for a variety of marine energy converters. The final reference model, an oscillating water column (OWC) device, has been completed. Key aspects of the Backward Bent Duct Buoy (BBDB) have been modeled and documented for public release. This model has […]
