Abstract: A method for the operation and control of gas filling from a filling station to a receiver is comprising actively controlling essential filling variables within the receiver such as temperature, pressure, and density of the gas; continuously updating estimates of the filling variables based on filling station side measurements interpreted using physical and thermodynamic relations as to make the variables available even when the receiver is not communicating with the filling station in so-called non-communication fueling; and continuously updating the estimated capacity of the receiver based on station side measurements in a non-communication fueling.

Abstract: A plant for storing and supplying compressed gas comprises a storage tank (1) for gas, at least one pressurization tank (2) for gas and a buffer tank (3) for a pressure support fluid to be filled into or evacuated from lower portions of the storage and pressurization tanks. The lower portions of the storage and pressurization tanks are communicating with the buffer tank via fluid flow lines (4, 5) to fill fluid during supplying from and pressurizing gas in the plant, and a flow line (7) for evacuating fluid during refilling of the pressurization tank.

Abstract: The present invention relates to a plant for storing gas under pressure. The plant includes at least one basin filled with a liquid, one or more pressure vessels located in the basin for storing the gas including interconnecting piping and connections to a gas supply and a gas discharge network, an anchoring system for supporting the vessels, a cover with a slanted surface on the underside for covering the basin which will lead any gas leak occurring in the basin towards and through a vent, and at least one gas detection equipment located in the vent. The plant is especially suitable for storing compressed gaseous hydrogen and can be connected to a hydrogen fuel replenishment system.
