Despite significant advancement in PV technology and efficiency, qualification testing and market penetration, actual performance in the field of operation under a myriad of environemental constraints remains an important topic. PV arrays are subject to degradation mechanisms that can significantly impact power production capability. For revenue-critical PV arrays, detection of underperformance an ...

Building Integrated Photovoltaics (BIPV) systems present significant challenges with respect to optimal energy efficiency of Photovoltaic (PV) arrays. In these systems, the PV panels replace roof tops, and other building components such as windows. Due to their diverse locations and orientations, influence of numerous environmental factors can significantly reduce the performance and overall eff ...

A key application of the technological breakthrough associated with decreased cost of DNA sequencing is metagenomics. Metagenomics is the process of sequencing DNA from whole ecosystems, rather than individuals or cultures. This approach has the potential to allow the dissection of microbial ecosystems in biofuel producing agricultural land, toxic contaminated sites and hydrocarbon recovery enviro ...

The injection and storage of captured CO2 in coal beds has been suggested as a strategy to reduce industrial emissions of CO2 into the atmosphere. The sequestration process involves the adsorption by coal of injected CO2 and an associated desorption of CH4 whose production can partially offset the operational cost. The acceptance of this strategy depends on: the ability to effectively monitor the ...

Solid State Drives (SSDs) are emerging as attractive alternatives to traditional HDDs due to there reduced power consumption and potential for increased performance. SSDs have the potential to improve the performance of both Checkpoint Restart (CPR) and the Metadata Server (MDS) for high performance File Systems, e.g., Lustre. However, the write performance of SSDs is relatively poor (compared to ...

Energy consumption is quickly becoming one of the primary bottlenecks of compute clusters and supercomputers. The DOE is a primary developer and consumer of these power hungry supercomputers, however smaller cluster machines are also widely used through other government agencies and industries. Yet, there are few power profiling tools that allow application developers transparent insight into the ...

Currently the commercially available technologies for H2 separation such as pressure swing adsorption and cryogenic distillation are very energy intensive. Membrane technologies can be very energy efficient; but for high selective membranes low flux and high cost are the major challenges that frustrate commercialization. Recently, cermet has shown promise because of less precious metal usage and m ...

Higher operating temperature for the gas turbine engine is needed for enhanced efficiency, lower emission and increased performance goal. The current state-of-the-art thermal barrier coatings (TBCs) are not adequate to provide the needed protection for the metallic components of the turbine engine operating at higher TBC surface temperature (>1300

Atmospheric aerosols influence the global radiation balance through direct scattering, and perhaps more importantly, through modification of the earth

Hydrogen produced today from coal, natural gas, or biomass must be separated and purified outside the reactors using pressure swing absorption (PSA), a process that requires significant additional space and energy. Placing hydrogen-permeable membranes inside the reactors themselves would allow hydrogen to diffuse out, thereby reducing the cost of hydrogen production. In this Phase I effort, Mainst ...
