Abstract: An intelligent pressure management system that controls the pressure inside a cryogenic tank between variable target vapor pressure values and/or ranges that are set as a function of system operating conditions, by actuating one or more actively controllable valves, based on a signal received from a pressure sensor that measures the pressure inside the pressurized tank. The variable target vapor pressure values and/or ranges are determined as a function of system operating conditions including the vapor volume in the storage space and a fluid flow demanded by the use device. The target vapor pressure can also be adjusted based on a geographical location, predictive system operation mode, a learned operator use pattern and/or a learned system use pattern.

Abstract: A method and system delivers a cryogenically stored fuel in a gaseous state into the air intake system of a gaseous fuelled internal combustion engine. The method involves measuring the pressure in the vapor space of the cryogenic storage vessel, comparing the measured pressure to a required fuel supply pressure and supplying fuel in gaseous state directly from the vapor space of the cryogenic storage vessel to the fuel delivery line that supplies fuel to the engine, when the pressure measured in the vapor space of the cryogenic storage vessel is equal to or higher than the required fuel supply pressure. The method further involves activating a cryogenic pump to deliver fuel to the internal combustion engine from the liquid space of the cryogenic storage vessel when the measured pressure in the vapor space is lower than the required fuel supply pressure.

Abstract: A multi-vessel fluid storage and delivery system is disclosed which is particularly useful in systems having internal combustion engines which use gaseous fuels. The system can deliver gaseous fluids at higher flow rates than that which can be reliably achieved by vapor pressure building circuits alone, and that keeps pressure inside the storage vessel lower so that it reduces fueling time and allows for quick starts thereafter. The system is designed to store gaseous fluid in liquefied form in a plurality of storage vessels including a primary storage vessel fluidly connected to a pump apparatus and one or more server vessels which together with a control system efficiently stores a liquefied gaseous fluid and quickly delivers the fluid as a gas to an end user even when high flow rates are required. The system controls operation of the pump apparatus as a function of the measured fluid pressure, and controls the fluid pressure in a supply line according to predetermined pressure values based upon predetermined system operating conditions.

Abstract: An intelligent pressure management system that controls the pressure inside a cryogenic tank between variable target vapor pressure values and/or ranges that are set as a function of system operating conditions, by actuating an actively controllable valve disposed on a gaseous fluid vapor conduit; and in some embodiments, additionally by actuating an actively controllable valve on a liquefied gaseous fluid conduit, based on a signal received from a pressure sensor that measures the pressure inside the pressurized tank. The variable target vapor pressure values and/or ranges are determined as a function of at least two system operating conditions which can include the vapor volume in the storage space; the fluid flow demanded by the use device; and a measured temperature parameter that correlates to the temperature of the fluid exiting a heater.
