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 […]

Sandia Wins DOE Geothermal Technologies Office Funding Award

The DOE’s Geothermal Technologies Office (GTO) selected twelve collaborative enhanced geothermal systems (EGS) R&D projects that will use novel techniques (such as isotope studies, innovative rock-mechanics experiments, and tracer studies integrated with geophysical methods) to increase the precision and accuracy of measuring critical underground reservoir properties over time. EGS are engineered reservoirs, created beneath the […]

Sandian Receives the Illuminating Engineering Society of North America, South Region Technical Award

The Illuminating Engineering Society (IES) builds on a century of excellence to create the premier lighting community dedicated to promoting the art and science of quality lighting to its members, allied professional organizations, and the public. This Regional Award is given in recognition of meritorious technical achieve­ment that has furthered the profession, art, or knowledge […]

New Sandia Mirror Isn’t Shiny: Instead It Reflects Infrared Light Using a Metamaterial

An optical wave’s reflection from metal arises from strong interactions between the optical electric field and the metal’s free carriers and is accompanied by a phase reversal of the reflected electric field. A far less common route to achieving high reflectivity exploits strong interactions between the material and the optical magnetic field to produce a […]
