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 [...]

Directly Coupled(r) Direct Current Microgrids

Savage P., Daudert J., Nextek Power Systems, US

Nextek is a pioneer in direct current (DC) power networks for buildings. The Nextek Direct Coupling® power distribution platform delivers superior efficiency, flexibility, and reliability to interior electrical circuits and on-site power generation. DC Systems; [...]

Thermodynamic Availability Sources from Inertial Energy

Celorio-Villasenor A., NATURBO Technology Centers, MX

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 [...]

Fiber Optic Sensors for High Temperature Monitoring

Rinaudo P., Torres Górriz B., Barrera Villar D., Sales Maicas S., Calderón García P.A., Javier Payá-Zaforteza I., Universitat Politècnica de València (Spain), ES

Recent events such as the fires on the Channel tunnel (1996), St. Gotthard (2001), the Twin Towers in New York (2001), The Windsor Building in Madrid (2005) and the collapse of the MacArthur Maze in [...]

Mobility of paramagnetic nanoparticles in porous media

Wang Y., Bagaria H., Zhang X., Johnson K., Abriola LM., Pennell KD., Tufts University, US

Stable paramagnetic nanoparticles were prepared and their mobility in reservoir matrix was measured as a function of particle mass loading, rate of sulfonate fraction in coating polymer, and the presence of surfactant.

Distributed Energy Storage Network Control

Jung J., Greensmith Energy Management Systems, US

Greensmith Energy Management System’s control architecture relies on two principles to create the most resilient and rapid control system available today. First, Greensmith builds a distributed network with localized intelligence at the unit level; such [...]

Ionic Liquids as Heat Transfer Medium

Schubert T.J.S., Sahin H., Götz M., Bär K., Buchholz D., Stiemke F., IOLITEC Ionic Liquids Technologies Inc., US

Ionic liquids are defined as pure salts with melting points below 100°C. Their high heat capacity, low vapor and incombustibly make them to promising candidates as thermal fluids. A limiting factor thereby is the resistance [...]
