Publication number: 20180172215Abstract: Embodiments are directed to compressed gas storage units exhibiting one or more safety features. Particular embodiments employ a pressure relief mechanism to rapidly yet safely vent the contents of the tank in the event of a fire. The mechanism may comprise an internally piloted relief valve in communication with temperature-sensitive element(s) present along the tank dimensions. Under high temperature conditions indicative of a fire, the element communicates a signal to open the internally piloted relief valve. In some embodiments the element is configured to communicate a heat signal (e.g., by thermal conduction). In certain embodiments the element is configured to communicate a pressure change signal (e.g., pneumatic, hydraulic). In other embodiments the element may communicate different signal types, such as electric (e.g., thermoelectric) or mechanical (e.g., shear or tension forces). Also disclosed is a module incorporating a plurality of tanks to offer enhanced storage capacity.Type: ApplicationFiled: February 14, 2018Publication date: June 21, 2018Inventors: Neel SIROSH, Edwin P. BERLIN, JR., Eric JOHNSON, Karthick CHANDRASEKER, Rodrigo SUSPERREGUY, Christopher PAIS, Danielle FONG

Patent number: 9909535Abstract: A fuel holding device is secured to a vehicle by means of straps and brackets, which sits on a system of gaskets to prevent longitudinal sliding and rotation. A gasket system for preventing longitudinal sliding is disposed circumferentially around the tank body, and between the tank body and a circumferential bracket system that includes a U-shaped strap and an L-shaped bracket. The gasket system comprises a wedge-shaped base and a slider portion, with the U-shaped strap secured around the slider portion. A system for preventing rotation of a fuel-holding device has a circumferential wedge gasket segment, or a corrugated segment, positioned at a gap between the U-shaped strap and the L-shaped bracket.Type: GrantFiled: October 4, 2013Date of Patent: March 6, 2018Assignee: QUANTUM FUEL SYSTEMS LLCInventors: Neel Sirosh, Derrin Lynn Olischefski

Patent number: 7868775Abstract: The present disclosure provides an alternative, cost-effective safety feature for on-board hydrogen storage containers incorporating a fill cycle sensor with a driver warning and shutdown system. The system monitors the number of times a hydrogen container is filled, and then takes action at a predetermined termination point. A controller monitors each time the hydrogen container is filled above 90% of the rated pressure or mass. Once the predetermined termination point of fill cycles is reached, the disclosed device/method will either disable the valve or refueling mechanism such that fuel supply to the vehicle is shutoff and the container cannot be filled again, essentially assuring the end of the life of the container.Type: GrantFiled: December 21, 2006Date of Patent: January 11, 2011Inventors: Neel Sirosh, Robert Miller, Tony Staples

Patent number: 6634321Abstract: Devices and methods for storing hydrogen fuels or other gaseous fuels. One embodiment of a container for storing gaseous fuels in accordance with an aspect of the invention comprises a high-pressure vessel configured to contain the gas in a high-pressure zone at a pressure significantly above atmospheric pressure. The container can also include a storing medium in the vessel and an inlet/outlet line extending through the vessel. The storing medium can have a plurality of storage spaces configured to physically bind molecules of the gas to the storing medium, and the inlet/outlet line can be a tube extending through the vessel in fluid communication with the storing medium. In operation, the high-pressure vessel is pressurized with a gaseous fuel (e.g., hydrogen) to a pressure significantly above atmospheric pressure (e.g., approximately 3,000-10,000 psi).Type: GrantFiled: December 14, 2000Date of Patent: October 21, 2003Assignee: Quantum Fuel Systems Technologies Worldwide, Inc.Inventors: Syed Hussain, Neel Sirosh

Patent number: 6041762Abstract: The controls for controlling the supply of natural gas fuel for a vehicle are integrated together in a module which is located at the gas tank. Such controls include a high pressure regulator for lowering the pressure of the gas flowing from the tank and an electronically controlled solenoid valve which shuts off the gas flow when no fuel is required by the engine and when the gas pressure in the tank falls below a predetermined value. Also included in the module are a pressure sensor for providing signals for controlling the shutoff valve; a check valve which permits one way flow of gas into the gas tank when it is filled; a pressure relief mechanism responsive to the temperature and pressure sensors for allowing safe release of the gas to the outside should the temperature rise above a predetermined limit.Type: GrantFiled: August 15, 1998Date of Patent: March 28, 2000Assignee: IMPCO Technologies, Inc.Inventors: Neel Sirosh, Syed Hussain, Eric G Adler, David Marley

Patent number: 5938209Abstract: A seal system for a pressure vessel which includes a substantially rigid outer shell with at least one opening therein, an inner liner disposed within the outer shell against the inside surface thereof, an opening aligned with the opening of the outer shell and a boss disposed in the opening of the outer shell. The boss includes a neck portion for fitting in the opening of the outer shell, a flange portion extending outwardly from one end of the neck portion and having an upper surface and a lower surface, and a generally cylindrical hollow substantially aligned with the outer shell opening and having an inwardly projecting annular shoulder. The lip segment of the liner extends radially inwardly under the lower surface of the flange portion of the boss and then upwardly into the hollow of the boss, along the interior wall of the hollow until a portion of the lip segment rests on the shoulder.Type: GrantFiled: February 14, 1997Date of Patent: August 17, 1999Assignees: Alternative Fuel Systems, Inc., Honda Giken Kogyo Kabushiki KaishaInventors: Sadanandan Neel Sirosh, Hans C.
