SWCNT/Inorganic polymer nanocomposite: a new class of Transparent Conductor and UV-Vis Photo – Generator

Bose S., Balaji S., Debnath R., Jadavpur University, IN

Synthesis of a light sensitive SWCNT/(Pb, Zn)-phosphate glass composite and it’s optical, light induced ESR, electronic and optoelectronic properties are reported. Absorption spectrum of SWCNTs of the composite differs from that of its film. Since [...]

Composites for Energy Applications

Infrared Sensor Interference Isolation for Low-Cost Three-Dimensional Anemometers

Hirano J., Garmire D., University of Hawaii at Manoa, US

The further integration of wind power generation into our power grids from residential and industrial building installations increases the need to gather high spatial resolution wind data. This results in a need for low-cost three-dimensional [...]

Self-Sufficient Smart-Grid Sensor Nodes and Architecture

Carland J., Oberbeck A., Umeda M., Cumming J., Wilkey T., Fripp M., Kuh A., Garmire D., University of Hawaii at Manoa, US

Energy systems of the future will be flexible and adaptive, capable of maximizing efficiency through sensing and predicting environmental and load conditions to effectively supply the right amount of power and mitigate grid issues. We [...]

Demand-Side Response from Industrial Loads

Starke M., Letto D., Alkadi N., George R., Johnson B., Dowling K., Khan S., ENBALA Power Networks, CA

With the adoption and integration of renewable resources that are often intermittent in nature, there appears to be an increased need for ancillary services and flexible resources to improve the reliability and efficiency of the [...]

Accomplishment: The development of a new cooling mechanism for gas turbines rotors (blades and disks). Cooling mechanism that utilizes a compressed liquid (hydrostatic) pressurized in rotating ducts or pipes with particular physical boundary conditions (no [...]

Bridging the Legacy and the Smart Grid: the Power Continuity Unit

Lank R., Trivedi S., DERP Technologies, LLC, US

In light of the massive storms that have hit the East Coast and the faltering reliability of the Grid, the need to add more distributed generation (DG) and to have more micro-grids is becoming increasingly [...]

A Controller Design for SEPIC in a Fuel Cell Battery

Noh M.D., Oh O-K., Kim S., Park Y.W., Chungnam National University, KR

A single-ended primary-inductance converter (SEPIC)is a DC/DC converter that has a wide input range and is ideal for a fuel cell. The controller for a SEPIC is often designed heuristically without the consideration of the [...]

Direct catalytic liquefaction of low-volatile hydrocarbons to clean light liquid fuels

Ganguli P.S., Energy Catalysis, Inc., US

Energy Catalysis, Inc. developed a direct catalytic liquefaction process for converting low-volatile heavy hydrocarbons such as coal, petroleum residuum, vacuum gas-oil, and tar sand bitumen into clean light liquid fuels. The technology concept was based [...]
