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 […]

Sandia Has Signed a Memorandum of Understanding with Case Western Reserve University

The memorandum of understanding (MOU) initiates a relationship between our institutions to better leverage our inherently complementary energy research strengths—focusing on R&D activity in utility-scale power and includes energy storage (batteries, capacitors), grid integration of renewable-energy resources, real-time residential and industrial energy management and control, lifetime degradation and science and various forms of advanced energy […]

Goal 2: Development of Prognostics and Health Management

Degradation Signature Characterization
The data from the characterization of parts before and after stress testing will be analyzed for useful fingerprints that indicate degradation and remaining lifetime. One approach is to apply the characterization results to simulations to look for corresponding changes in behavioral parameters of the inverters. Figure 1 describes one potential behavioral parameter, voltage […]

National Solar Thermal Testing Facility Beam Profiling

On Thursday, June 7, we began beam profiling the NSTTF field heliostat beam.  Using the “Hot 80” heliostats aimed at a single aimpoint on a vertical target, the peak flux was 192 W/cm2.  Using the remaining 128 heliostats (the Cool 128) aimed at a single aimpoint on a vertical target, the peak flux was 152 […]
