A fuel tank for storing a hydrogen liquid carrier and a spent hydrogen liquid carrier includes a substantially rigid exterior tank wall including a first chamber and a second chamber. The first chamber is fluidly disconnected from the second chamber, and the second chamber includes a dynamically expandable and contractible enclosure, the enclosure being configured to define a dynamic boundary between the hydrogen liquid carrier and spent hydrogen liquid carrier. The fuel tank also includes a first channel in flow communication with one of the first chamber or the second chamber and a second channel in flow communication with another of the first chamber or the second chamber, wherein the first channel and the second channel are flow connected such that a flow through one of the first or second channels is returned to the another of the first or second channels, and that during the flow, the dynamic boundary changes position causing a change in a volume of the second chamber.

A system for extracting hydrogen gas from a liquid hydrogen carrier may include a hydrogen gas reactor, a catalyst for facilitating extraction of the hydrogen gas from the liquid hydrogen carrier, and a reservoir for containing the liquid hydrogen carrier and a spend liquid hydrogen carrier. The system may be configured to regulate a flow of liquid hydrogen carrier in and out of the hydrogen gas reactor, to move a catalyst relative to a volume of the liquid hydrogen carrier, and to provide a continuous flow of the hydrogen gas, in response to a demand for the hydrogen gas.

The present invention relates to high efficient tubular catalytic steam reforming reactor configured from about 0.2 inch to about 2 inch inside diameter high temperature metal alloy tube or pipe and loaded with a plurality of rolled catalyst inserts comprising metallic monoliths. The catalyst insert substrate is formed from a single metal foil without a central supporting structure in the form of a spiral monolith. The single metal foil is treated to have 3-dimensional surface features that provide mechanical support and establish open gas channels between each of the rolled layers. This unique geometry accelerates gas mixing and heat transfer and provides a high catalytic active surface area. The small diameter, high aspect ratio tubular catalytic steam reforming reactors loaded with rolled catalyst inserts can be arranged in a multi-pass non-vertical parallel configuration thermally coupled with a heat source to carry out steam reforming of hydrocarbon-containing feeds. The rolled catalyst inserts are self-supported on the reactor wall and enable efficient heat transfer from the reactor wall to the reactor interior, and lower pressure drop than known particulate catalysts. The heat source can be oxygen transport membrane reactors.
