Embodiments of systems and methods for transporting fuel and carbon dioxide (CO.sub.2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with two or more inner compartments, positioned within the outer shell, including a first inner compartment for storing CO.sub.2 and a second inner compartment for storing fuel. The dual-fluid vessel may connect or attach to a transportation vehicle to thereby allow transportation of the fuel and CO.sub.2. Insulation may provide temperature regulation for the fuel and CO.sub.2 when positioned in the respective first and second inner compartments. One or more ports having an opening in and through the outer shell and a fluid pathway to one or more of the first inner compartment or the second inner compartment may provide fluid communication through the opening and fluid pathway for loading/offloading the fuel and/or CO.sub.2.

Container systems for the transportation and/or storage of Liquefied Natural Gas (LNG) are provided. The container systems include: a) an outer shell; b) an inner pressurized container, wherein the inner pressurized container comprises a first chamber having a first vent and at least one other chamber having a second vent; c) at least one heat exchange zone in thermal communication between the first chamber and the at least one other chamber; and d) an interstitial space between the outer shell and the inner pressurized container including at least a partial vacuum. Methods for transporting and/or storing LNG using the aforementioned container systems are also provided.

Storage systems and methods of manufacturing and using the same. A storage tank is provided with an inner vessel, an outer vessel, and a support system between the vessels. The support system may comprise a repeating pattern of openings that effectively lengthens the heat path between the inner and outer vessels.

The present invention relates to a preparation of a block of fiber-reinforced polyurethane/polyisocyanurate foam in which the expansion of the foam is constrained by the walls of a double belt laminator forming a tunnel, the block of fiber-reinforced polyurethane/polyisocyanurate foam being composed of cells storing a gas, advantageously having low thermal conductivity, and exhibiting a density of less than 50 kg.m.sup.−3 with a content of fibers C.sub.f representing at least 4% by weight of the block of fiber-reinforced foam, in which the impregnation time of the fibers t.sub.i is less than the cream time t.sub.c of the polyurethane/polyisocyanurate foam.

The invention relates to a corner structure (16) for a leaktight and thermally insulating tank for storing a fluid, comprising a plurality of walls (1, 101, 201); the said corner structure (16) being intended to be arranged in a corner between a first wall (101) and a second wall (201) and comprising: a first angle bracket (32) anchored to an anchoring device (16) intended to be fastened to the supporting structure (3) of the first and second walls (101, 201); the anchoring device (16) comprising a first tab (18) and a second tab (19) intersecting one another, each of the first and second tabs (18, 19) comprising an external portion (24, 25) and an internal portion (22, 23) which are arranged on either side of an intersection between the first tab (18) and the second tab (19); the corner structure (16) furthermore comprising a first insulating panel (42) which is arranged in a first space delimited by the internal portion (22) of the first tab (18) and the external portion (25) of the second tab (19), and a first lateral insulating packing element (48) which is compressed between the first insulating panel (42) and the external portion (25) of the second tab (19).
