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 [...]

More California Gas Stations Can Provide Hydrogen than Previously Thought, Sandia Study Says

A study by Sandia researchers concludes that a number of existing gas stations in California can safely store and dispense hydrogen, suggesting a broader network of hydrogen fueling stations may be within reach. The report examined 70 commercial gasoline stations in the state and sought to determine which, if any, could integrate hydrogen fuel, based [...]

Energy Department Awards $7M to Advance Hydrogen Storage Systems

Sandia researcher Chris San Marchi displays components the team has studied for compatibility with hydrogen. Gaseous hydrogen has the unique characteristic that it liberates atomic hydrogen when in contact with surfaces. The released atomic hydrogen dissolves into materials and can alter their structural properties, a process often referred to as hydrogen embrittlement. On [...]

Renewables, Other Energy Issues To Be Focus of Enhanced Sandia-SINTEF Collaboration

Under an expanded agreement, a decades-long partnership between Sandia and the Norwegian research organization SINTEF (Stiftelsen for industriell og teknisk forskning) will now tackle energy challenges such as renewable-energy integration, grid modernization, gas technologies, and algae-based biofuels. SINTEF is the largest independent research organization in Scandinavia, with expertise in the natural sciences and technology, the [...]

New Polarized-Depolarized Measurement Capability Extends Use of Raman/Rayleigh Methods to More Flame Types

Figure 1.  A second Raman/Rayleigh line-imaging detection unit allows researcher to simultaneously measure polarized and depolarized components of Raman scattering signals, helping to overcome fluorescence interference from soot precursors in hydrocarbon flames. Allowing single-shot measurements of all major species in nonsooting flames of simple fuels, such as H2 and CH4, spontaneous Raman scattering [...]
