Abstract: Instead of CCS technique, a possible approach to mitigate the greenhouse gas (GHG) emission is to decompose it into useful products. This invention shows a high temperature rechargeable battery system for decomposition of oxygen-containing gases (e.g CO2/H2O, NOx, SOx, in particular GHG), oxygen generation, and energy storage by using ODF/La2NiO4-based materials in Li/Ti/Mg—CO2 battery architecture. Different from ionic Lithium conducting electrolyte, the invention has a higher ionic oxygen conducting electrolyte to work efficiently at higher temperature without sacrificing safety. During battery discharge, GHG can be decomposed into syngas (CO+H2) or solid carbon, while renewable energy (e.g. solar/wind power) could be used to charge the battery and generate oxygen. The energy consumption for GHG decomposition is self-sustainable and the byproducts (i.e. carbon/syngas and oxygen) have good market values.

Abstract: The disclosure provides a method for the production of composite particles utilizing a mechano chemical bonding process following by high energy ball milling on a powder mixture comprised of coating particles, first host particles, and second host particles. The composite particles formed have a grain size of less than one micron with grains generally characterized by a uniformly dispersed coating material and a mix of first material and second material intermetallics. The method disclosed is particularly useful for the fabrication of oxide dispersion strengthened coatings, for example using a powder mixture comprised of Y2O3, Cr, Ni, and Al. This particular powder mixture may be subjected to the MCB process for a period generally less than one hour following by high energy ball milling for a period as short as 2 hours. After application by cold spraying, the composite particles may be heat treated to generate an oxide-dispersion strengthened coating.

Abstract: This invention shows a high temperature rechargeable battery system for energy storage, oxygen generation, and decomposition of oxygen-containing gases (e.g. CO2/H2O, NOR, SOx, in particular greenhouse gas (GHG)) by using ODF/La2NiO4-based materials in Li/Ti/Mg-CO2 battery architecture. Different from ionic Lithium conducting electrolyte, the invention has a higher ionic oxygen conducting electrolyte to work efficiently at elevated temperature without sacrificing safety. During battery discharge, GHG can be decomposed into syngas (CO+H2) or solid carbon, while renewable energy (e.g. solar or wind power) can be used to charge the battery and generate oxygen. The energy consumption for GHG decomposition is self-sustainable and the byproducts (i.e. carbon/syngas and oxygen) have good market values. The adoption of cost effective materials other than Lithium is significant for scaled-up applications and represents an entirely new approach.

Abstract: Oxygen Deficient Ferrites (ODF) electrodes integrated with Yttria Stabilized Zirconia (YSZ) electrolyte, electrochemically decompose carbon dioxide (CO2) into carbon (C)/carbon monoxide (CO) and oxygen (O2) in a continuous process. The ODF electrodes can be kept active by applying a small potential bias across the electrodes. CO2 and water (H2O) can also be electrolyzed simultaneously to produce syngas (H2+CO) and O2 continuously that can be fed back to the oxy-fuel combustion. With this approach, CO2 can be transformed into a valuable fuel source allowing CO2 neutral use of the hydrocarbon fuels.
