R&D 100 Entry: QuESt @SandiaLabs

Uploaded June 2020 | Updated September 2026, 3 weeks ago

Sandia National Labs introduces QuESt, an open source software application suite for energy storage valuation. Basically, it helps users find answers to questions about the technical performance of an energy storage system.

QuESt incorporates the technical expertise and institutional knowledge developed over many years by the energy storage analytics team at Sandia. The software incorporates mathematical algorithms and models from studies conducted by the Sandia team. QuESt also has a suite of innovative features such as built-in support and acquisition tools for the most widely used online data resources and automated report generation to summarize analysis in a comprehensive document.

QuESt was developed out of an initiative to help reduce the barriers for the widespread adoption of energy storage. It empowers the public at large with the told to make informed decisions about investments in energy storage. By doing so, the way can be paved for potentially transformative technologies to enhance the energy sector and, consequently, the general population’s way of life.

$Research Capabilities of Sandias Geomechanics Laboratories Walter Hermann founded the Geomechanics Department and Geomechanics Laboratory in 1972–1973 to support weapons programs, primarily nuclear testing, effects, and containment studies at the Nevada Test Site. Since then, the Sandia Geomechanics Department has developed a variety of laboratory proficiencies and numerical modeling expertise that support environmental management, nuclear nonproliferation, defense and industry, and basic energy sciences. The Geomechanics Department’s experimental facilities enable study of complex processes and systems through measurement of coupled mechanical, thermal, hydrologic, and chemical properties under a wide range of conditions including very high pressures (1 GPa) and complex load paths. Using both standard and unique capabilities, customer needs for assessment of geomaterial response to natural and engineered conditions are addressed through the design and conduct of sophisticated experiments. JASON (2014) declared the Geomechanics Laboratory to be the flagship facility of its type for the National Nuclear Security Administration and Department of Energy, highlighting its high pressure triaxial and other testing capabilities, available as a DOE user facility well into the foreseeable future. Making predictions of complex multiphysics response of geomaterials requires quantitative models of the governing deformation, fracture processes, fluid flow, or other behaviors. Building constitutive models and performing analytic and numerical calculations requires information about specific rock properties. Sandias geomechanics laboratories experimentally simulate in situ conditions at depth in the earth with high pressure, differential stresses, multi-phase fluid flow, high strain rates (10^4 /s), and elevated temperature. The Geomechanics Department’s expertise lies in both validating and developing constitutive models. SAND 2021-1421V$
