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 [...]

Electrospun Nanofiber Membranes and Electrodes for Fuel Cells

Wycisk R., Ballengee J., Park J.W., Brodt M., Pintauro P.N., Vanderbilt University, US

The focus of our research group has been on the use of electrospinning for the fabrication of nanofiber membranes and electrodes for PEM fuel cells. We have demonstrated dramatic improvement in fuel cell performance and [...]

Renewable Energy Technology Gains by Interfacial Engineering with Carbon Nanomaterials

Vander Wal R.L., The Pennsylvania State University, US

Creating a new paradigm, nanomaterials, when used as interfacial modifiers have the potential to significantly alter the energy landscape, given that these processes occur predominantly at interfaces. The key concept is that the nanomaterials serve [...]

Complex Adaptive Systems – Energy Metrologies for Nanobiomaterials in Artificial Photosynthesis

Greer M., Lockheed Martin, US

Municipal street and public space lighting serve critical safety and security functions but their associated costs can be one of the more significant items in O&M budgets. While the concept of Bio LED trees have [...]

Separation of Nanoparticles from Nanoparticle Enhanced Phase Change Material

Haroon Sheikh M., Sharif M.A.R., Rupar P.A., University of Alabama, US

The phase change materials(PCM) have been used to store energy as a latent heat of fusion. Paraffin oils are proved to be the best suitable material as a PCM, however its heat capacity is lower [...]

Three-dimensional Core@Shell Nano-Array Electrodes for Integrated Lithium-Ion Microbatteries

Mao Y., Sun X., Li Q., Lv Y., University of Texas-Pan American, US

In micro/nanoelectromechanical systems (MEMS/NEMS) and biomedical devices, the desired on-board power storage and delivery occur in exceptionally small geometric scales, where amount of energy stored on given footprint (J/mm2) precedes that in either unit weight [...]

Large Scale Energy Storage with Thermal Matrix Energy Storage

Sutherland S., Lynch G., Pietsch T., Kelvin Storage Technologies, Inc, US

The presentation reviews the design and technical innovations for storing energy as heat in a graphite core at temperatures far above the melting point of steel. The high temperatures reached, over 4000F, enable storing vast [...]

Rechargeable Nanofluid Electrodes for High Energy Density Flow Battery

Timofeeva E.V., Katsoudas J.P., Segre C.U., Singh D., Argonne National Laboratory, US

Nanomaterial suspensions in liquids (nanofluids) are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow [...]

Novel Electrolytes for Supercapacitors

Stiemke F., Blumenröder B., Schubert T.J.S., IOLITEC Ionic Liquids Technologies Inc., US

Supercaps using ionic liquids (ILs) as novel electrolytes have gained much attention because of their interesting profiles of physical and chemical properties , such as tunable viscosities and conductivities, chemical and thermal stability as well [...]
