Patent number: 8152873Abstract: A system is disclosed to generate hydrogen. The system includes a fuel cartridge, a cartridge interface, and a fuel cartridge receiver. The fuel cartridge includes a liquid permeable material with one or more cavities that encloses a solid anhydrous chemical hydride. The fuel cartridge also includes a housing that is heat and pressure resistant that houses the liquid permeable material, and a liquid. The fuel cartridge also includes one or more liquid sources that introduce the liquid into the housing such that the liquid contacts at least a portion of the liquid permeable material.Type: GrantFiled: December 22, 2009Date of Patent: April 10, 2012Assignee: Trulite, IncInventors: Kevin Shurtleff, Eric Ladd, John Patton, Chris Brydon, Ken Pearson

Publication number: 20110027670Abstract: An apparatus is disclosed to generate electric power from a chemical hydride. A fuel cartridge produces hydrogen by reacting a liquid with a chemical hydride. A fuel cell stack generates electric power using an oxygen source and the produced hydrogen. An electric power storage device is coupled with the fuel cell stack. The electric power storage device stores and supplies electric power. One or more liquid sources inject the liquid into the fuel cartridge at a variable rate. A controller calculates a liquid injection rate for the one or more liquid sources based on power demands of an electric load.Type: ApplicationFiled: December 17, 2009Publication date: February 3, 2011Applicant: TRULITE INC.Inventors: Kevin Shurtleff, Eric Ladd, John Patton, Chris Brydon, Ken Pearson

Patent number: 7802423Abstract: A system and method for the reduction of NOx emissions from combustion sources are provided. The system includes a fuel tank, fuel converter unit, condensor unit, selective catalytic reduction (SCR) unit and an engine. The condenser unit includes a generally cylindrical inner wall defining a cavity having a first lower end and a second upper end, the first lower end is configured to include a gas inlet for receiving a gas mixture from the fuel converter and the second upper end is configured to include a gas outlet in fluid communication with the SCR unit. A heat exchanger is disposed within the cavity of the condensor unit to contact the gas mixture and separate heavy hydrocarbons from light hydrocarbons, wherein the light hydrocarbons are fed to the SCR unit and the heavy hydrocarbons are condensed and either send back to the fuel tank or directly to the engine for combustion.Type: GrantFiled: August 21, 2006Date of Patent: September 28, 2010Assignee: General Electric CompanyInventors: Arnaldo Frydman, Ke Liu, Gregg Anthony Deluga, David Eric Ladd

Patent number: 7651542Abstract: An apparatus is disclosed to generate hydrogen. A liquid permeable material with one or more cavities contains a solid anhydrous chemical hydride and an anhydrous activating agent. A housing that is heat and pressure resistant houses the liquid permeable material, and a liquid. One or more liquid sources inject the liquid into the housing such that the liquid contacts at least a portion of the liquid permeable material. A gas outlet port releases hydrogen gas produced by a reaction comprising the solid anhydrous chemical hydride, the anhydrous activating agent, and the liquid. A hydrogen output regulator controls the amount of hydrogen gas that the gas outlet port releases.Type: GrantFiled: July 26, 2007Date of Patent: January 26, 2010Assignee: Thulite, IncInventors: Kevin Shurtleff, Eric Ladd, John Patton, Chris Brydon, Ken Pearson

Publication number: 20070189940Abstract: The apparatus includes a liquid permeable pouch that defines a cavity for maintaining an anhydrous hydride reactant, wherein the cavity comprises a cross-section such that a point within the cross-section is separated from a perimeter of the liquid permeable pouch by no more than double the permeation distance, and a cartridge configured to receive the liquid permeable pouch and a liquid reactant such that at least a portion of the liquid permeable pouch is submerged in the liquid reactant. The system includes a plurality of pouches formed from two rectangular sheets of liquid permeable material, and each pouch has a width selected such that each point within a cross-section is separated from the sheets by no more than double the permeation distance. The method includes joining the sheets, forming one or more seals to define a cavity, disposing anhydrous hydride within the cavity, and sealing the opening.Type: ApplicationFiled: April 26, 2007Publication date: August 16, 2007Inventors: James Shurtleff, John Patton, Eric Ladd
