Stephen Larter has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11411231
    Abstract: The invention provides a membrane-free redox cell utilizing auxiliary electrodes that facilitate fast charging and discharging of anolyte and catholyte for electrochemical energy storage. The anode and cathode chambers are ionically separated, and electrically connected through a conductor joining auxiliary electrodes comprised of a redox material. In use, charging/discharging of the galvanic cell takes place between primary electrodes, and the redox material is immersed in the electrolyte in both anode and cathode chambers.
    Type: Grant

  • Publication number: 20100212893
    Abstract: The invention relates to systems and methods for catalytic down-hole upgrading of heavy oil and oil sand bitumens. The method enables upgrading heavy oil in a production well within a hydroprocessing zone including the steps of: introducing a controlled amount of heat to the hydroprocessing zone; introducing a selected quantity of hydrogen to the hydroprocessing zone to promote a desired hydrocarbon upgrading reaction; and, recovering upgraded hydrocarbons at the surface. The invention further includes the hardware capable of performing the method.

  • Publication number: 20070298479
    Abstract: A process for stimulating microbial hydrogen production in a petroleum-bearing subterranean formation, comprising: (a) analyzing one or more components of the formation to determine characteristics of the formation environment; (b) detecting the presence of a microbial consortium, comprising at least one fermentative syntrophic microorganism, within the formation; (c) assessing whether the formation microorganisms are currently active; (d) determining whether the microbial consortium comprises one or more fermentative syntrophic microorganisms; (e) characterization of one or more fermentative syntrophic microorganism of the consortium, and comparing the one or more characterized organisms with at least one known characterized known microorganism having one or more known physiological and ecological characteristics; (f) characterizations of one or more hydrogen consuming microorganism, such as (but not exclusively) methanogens and sulphate reducers, of the consortium, and comparing the one or more characterize

  • Publication number: 20070251146
    Abstract: A process for stimulating microbial methane production in a petroleum-bearing subterranean formation, comprising: (a) analyzing one or more components of the formation to determine characteristics of the formation environment; (b) detecting the presence of a microbial consortium, comprising at least one methanogenic microorganism, within the formation; (c) assessing whether the formation microorganisms are currently active; (d) determining whether the microbial consortium comprises one or more methanotrophic microorganism; (e) characterization of one or more microorganisms of the consortium, at least one of the members of the consortium being a methanogenic microorganism, and comparing the members of the consortium with at least one known microorganism having one or more known physiological and ecological characteristics; (f) characterization of one or more methanotrophic microorganisms of the consortium (if present), and comparing the members of the consortium with at least one known microorganism having one
