INDIUM ZINC-BASED ALLOY ANODES FORMING POROUS STRUCTURE FOR AQUEOUS ZINC BATTERIES (iEdison No. 0685901-22-0044)
A series of InxAlyZnz (x≤0.15, y≤0.02 z ≥0.83) anodes that can form porous structure during battery cycling have been developed to achieve enhanced stability for zinc-based batteries. These anodes can be achieved through electrodeposition or other methods. These anodes during cycling result in a porous In2O3 surface that allows for zinc to be deposited into and onto the pores. The materials have result in lower cell polarization and higher cycle life without dendrite formation.
SYSTEM AND METHOD FOR DIRECT AIR CAPTURE OF WATER AND CO2 (iEdison No. 0685901-21-0127)
A system is described where water vapor in the air is extracted with a desiccant and used to perform a humidity swing to release CO2 from a moisture responsive sorbent. A passive heat transfer mechanism is used to maintain constant temperature throughout the process and so requires no external heat source to operate. The process produces a large amount of potable water along with CO2, which enhances siting options where water scarcity is an issue, provides a second source of revenue that improves financial returns, and magnifies the environmental benefits of removing CO2 from the atmosphere.
Energy Storage Devices Having Anodes Containing Mg and Electrolytes Utilized Therein
For a metal anode in a battery, the capacity fade is a significant consideration. In energy storage devices having an anode that includes Mg, the cycling stability can be improved by an electrolyte having a first salt, a second salt, and an organic solvent. Examples of the organic solvent include diglyme, triglyme, tetraglyme, or a combination thereof. The first salt can have a magnesium cation and be substantially soluble in the organic solvent. The second salt can enhance the solubility of the first salt and can have a magnesium cation or a lithium cation. The first salt, the second salt, or both have a BH4 anion.
Hybrid Energy Storage System Utilizing Redox Active Organic Compounds
Redox flow batteries (RFB) have attracted considerable interest due to their ability to store large amounts of power and energy. Non-aqueous energy storage systems that utilize at least some aspects of RFB systems are attractive because they can offer an expansion of the operating potential window, which can improve on the system energy and power densities. One example of such systems has a separator separating first and second electrodes. The first electrode includes a first current collector and volume containing a first active material. The second electrode includes a second current collector and volume containing a second active material. During operation, the first source provides a flow of first active material to the first volume. The first active material includes a redox active organic compound dissolved in a non-aqueous, liquid electrolyte and the second active material includes a redox active metal.
Self Assembled Multi-Layer Nanocomposite of Graphene and Metal Oxicde Materials
Controlled graphene metal oxides organized on the nanoscale. The metal oxides can be SiO2, SnO2, and any other oxides and mixed oxides. The metal oxides can be replaced by a polymer or phosphate materials. The nanocomposites can be used for energy storage, sensing, catalyst support, and other applications. The graphene can be dispersed in the metal oxides. The grapehne and metal oxides can form alternative layered composites. The final materials can be mesoporous and conductive.
SYSTEM AND METHOD OF DESIGNING MODELS IN A FEEDBACK LOOP
A diagnostic model design system is provided that is driven by a combination of statistical aggregation methods, ensemble analysis techniques, and model specification strategies. The system takes as input a collection of disparate information (e.g. predictive machinery, numerical models, conceptual models, and/or expert opinions) where the information is attempting to estimate a common process or outcome. Optionally the system can also take real-world observation data. Through the system: the strengths and weaknesses of information and information sources can be identified; information sources can be ranked by reliability; and, a basis for designing and validating new, more reliable and accurate information sources (new models, machinery, etc) is provided.
Forward-looking transactive pricing schemes for use in a market-based resource allocation system
Disclosed herein are representative embodiments of methods, apparatus, and systems for distributing a resource (such as electricity) using a resource allocation system. One of the disclosed embodiments is a method for generating a bid value for purchasing electricity in a market-based resource allocation system. In this embodiment, a desired performance value indicative of a user's desired performance level for an electrical device is received. Price information from an electricity futures market is received. A bid value for purchasing electricity from a local resource allocation market sufficient to operate the electrical device at the desired performance level is computed. In this embodiment, the computing is performed based at least in part on the desired performance value and based at least in part on the price information from the electricity futures market.
Forward-looking transactive pricing schemes for use in a market-based resource allocation system
This is an extension of the Invention Disclosure for the Olympic Peninsula Demonstration Project. In this project, a rolling window of 24 hours was used to determine average price and standard deviations. The new method uses day ahead pricing to calculate similar values.
Hybrid Energy Storage Devices Having Sodium
The present invention discloses a novel ZEBRA-type sodium-sulfur (Na-S) battery. The cathode consists of active material of sulfur mixed with Ni current collector. NaAlCl4 is employed as the catholyte, which is similar to that in ZEBRA batteries. This new type of battery retains most of the advantages of the state-of-the-art Na-S and ZEBRA batteries while overcoming the related deficits. The most attractive features of this new battery are the lower operating temperature, higher energy density and better cycle life than both Na-S and ZEBRA batteries, which makes it suitable for renewable integration and grid applications, along with commercial or fleet transportation.
