The invention relates to a marine vessel cryogenic barrier which is formed of a plurality of individual panels, each panel being arranged to align with an adjacent panel on an inner surface of a hold space of a marine vessel and comprising a single coupling means at the centre of the panel and an impervious layer on a surface of the barrier facing the hold space.

The invention relates to an installation for storing and distributing cryogenic fluid, for example liquid hydrogen, comprising a cryogenic reservoir which is buried below the ground, a liquid withdrawal circuit connected to the reservoir with a downstream end located above the ground and designed to be connected to a consumer, the withdrawal circuit comprising a cryogenic pump arranged above the ground, the installation comprising a pipe for the recovery of vaporization gas generated inside the cryogenic pump, having a downstream end connected to the reservoir, the pipe for the recovery of the vaporization gases comprising at least one device for controlling the pressure and/or flow rate of the vaporization gas returned to the reservoir and the device for controlling the pressure and/or flow rate being configured to control the pressure inside the reservoir at a pressure level which is greater than the pressure at the inlet of the cryogenic pump.

The present invention discloses a solid-state source gasification device, comprising a housing and one or more trays, a top cover is provided on the top of the housing. A gas inlet and a gas outlet are provided on the top cover. The trays are vertically stacked in the housing. A carrier gas pipe is provided in the housing. An upper end of the carrier gas pipe is connected to the gas inlet. The carrier gas pipe penetrates through the trays, and extends into the bottommost-layer tray. One or more carrier gas outlets are formed in the carrier gas pipe. The carrier gas outlets are formed in a space of the bottommost-layer tray or formed in a space of the bottommost-layer tray and the rest trays. Except for the bottommost-layer tray, the rest trays are each provided with one or more gas conduits. The solid-state source gasification device of the present invention adopts a parallel gas transmission channel, whereby the carrier gas, after entering the carrier gas pipe from the gas inlet, can enter into each tray separately, and can be transmitted horizontally in each tray along the surface of the solid-state source material for a longer distance before reaching gas conduit, and thus a large amount of gasification gas can be carried in the carrier gas to enhance the overall gasification efficiency of the solid-state source gasification device.
