Abstract: A pressure vessel mounting system for mounting a pressure vessel to a vehicle chassis is disclosed. In various embodiments, the system includes a first end frame; a second end frame spaced a distance from the first end frame, the distance being sufficient to receive a pressure vessel between the first end frame and the second end frame; a first side frame extending between the first end frame and the second end frame, the first side frame configured for coupling to a first chassis rail of the vehicle chassis via at least one of the first end frame and the second end frame; and a second side frame extending between the first end frame and the second end frame. Via use of the pressure vessel mounting system, impact damage to pressure vessels may be reduced and/or eliminated.

Abstract: A pressure relief system comprises a pressurized vessel containing a fuel source and comprising a thermal pressure relief device, a heat shield coating disposed on an outer surface of the pressurized vessel, a sensor in thermal communication with the heat shield and configured to receive thermal energy from the heat shield, and an electronic control module electrically coupled to the sensor and the thermal pressure relief device. The sensor, responsive to receiving a threshold amount of thermal energy from the heat shield coating, may transmit a signal to the electronic control module. The electronic control module may activate the thermal pressure relief device in response to the signal.

Abstract: A system for transferring and igniting a fuel comprising a fuel supply and a cryogenic fuel processor connected to the fuel supply and operative to remove impurities from the fuel. The system includes a power supply and an injector-igniter. The injector-igniter includes an injector housing connected to the power supply and having a fuel inlet connected to the fuel processor. An actuator body is disposed in the housing and a conductor sleeve is connected to the power supply and supported between the actuator body and injector housing with a first annular gap between the injector housing and the conductor sleeve. There is also a second annular gap between the actuator body and conductor sleeve, wherein the first and second annular gaps are in fluid communication with the fuel inlet, whereby fuel provides a dielectric between the conductor sleeve and the injector housing.
