Development and Applications of Custom Amorphous Fluoropolymers (CAF)

Feiring A.E., Shangguan N., Lousenberg R.D., Majumdar S., Murnen H., Nemser S., Compact Membrane Systems, Inc., US

The amorphous perfluoropolymer, Teflon™ AF, developed and commercialized by the DuPont Company, contains two monomers, perfluoro-2,2-dimethyl-1,3-dioxole (PDD) and tetrafluoroethylene (TFE). In common with most perfluoropolymers, the PDD/TFE copolymer has an extraordinary combination of properties such [...]

Engineered response materials for oil and gas

Sherman A., Terves Inc, US

Engineered response materials- materials that are designed to respond to wellbore conditions to do something, enable significant reductions in drilling and completion costs. Specific responses now available for incorporation into new tools and processes include [...]

Electrochemical Sensors for Gas Pipelines Using Ion Conducting Membranes

Ziomek-Moroz M., National Energy Technology Laboratory, US

Electrochemical sensors are regularly used for the detection of chemical species in many industrial operations. The most common example is potentiometric measurement of pH, and oxygen quantity (e.g. the Clark electrode) and corrosion sensors also [...]

Advances in Next-Generation Polyolefin Standard Reference Materials

Orski S.V., Farrell W.S., Beers K.L., NIST, US

Advanced synthetic processes and novel metal-based catalysts have revolutionized manufacturers’ ability to tailor molar mass, polydispersity, and degree of short chain branching into polyolefin plastics synthesized from petrochemical feedstocks. These capabilities have resulted in polymers [...]

Heat Resistant Advanced 9% Cr Steel for Fossil Energy Power Generation

Hawk J., Jablonski P., National Energy Technology Laboratory, US

Alloys used in fossil energy power generation must be stable for extended times with some components having expected lifetimes of up to 30 years. For temperatures in excess of 600C, advanced 9% Cr steels are [...]

Using in situ Neutron Reflectometry to Study Solid-Electrolyte Interphase Formation in aSi and Sn Anode Materials

Kim J., Doucet M., Veith G., Browning J., Oak Ridge National Laboratory, US

Interfacial reactions between liquid electrolytes and electrode surfaces in energy storage devices are responsible for their long-term behavior and may mediate certain safety concerns regarding unwanted oxidation/reduction of the electrolyte. These reactions occur when an [...]

Preliminary Performance Evaluation of a Ground-Level Integrated Diverse Energy Storage (GLIDES) Prototype System

Odukomaiya A., Abu-Heiba A., Gluesenkamp K.R., Abdelaziz O., Graham S., Momen A.M., Oak Ridge National Laboratory/Georgia Institute of Technology, US

Due to the increasing generation capacity from intermittent renewable electricity sources being brought on-line, and an electrical grid ill-equipped to handle the mismatch between electricity generation and use, there is a critical, growing need for [...]

Efficiency Improvement Techniques for Liquid Piston based Ocean Compressed Air Energy Storage

Patil V.C., North Carolina State University, US

Intermittent renewable energy resources need energy storage system for their optimal utilization. Utilization of renewable energy resources can be improved through incorporating utility-scale energy storage in power grid. Ocean compressed air energy storage (OCAES) is [...]

Molecular Modeling of Carbon-Based Electrochemical Double Layer Capacitors

Schweizer S., Hill J.-R., Subramanian L., Scienomics, US

Powerful energy storage technologies are key to meet the ever increasing demand in energy in a sustainable manner. Electrochemical double layer capacitors (EDLCs), which are also known as supercapacitors, are energy storage elements which are [...]

Low cost and reliable sodium-metal halide (Na-MH) batteries for stationary energy storage application

Li G., Pacific Northwest National laboratory, US

Stationary electric energy storage devices have gained increasing prominence due to great market needs, such as smoothing availability of renewable energy resources and supporting the reliability of the electric grid. Among various battery technologies, with [...]
