The invention relates to a tank for storing hydrogen by absorption into a hydrogen-storage material. The tank contains a chamber, a hydrogen feed inlet, a hydrogen discharge outlet, and an inner structure for storing the hydrogen-storage material. The inner structure contains a stack along a longitudinal axis of at least two levels for containing the storage material. Each level includes a distributor cup, a receiver cup for the storage material, and a collector cup. The distributor cups, receiver cups and collector cups are stacked one on top of the other and rigidly and sealingly connected to one another. The invention also relates to a distribution pipe distributing in parallel hydrogen in the distributor cups such that, for each level, hydrogen flows from each distributor cup to the collector cup by passing through the storage material.

Disclosed is a marine vessel to transport natural gas hydrates (NGH), the marine vessel includes a hull formed from solid NGH and a skeletal structure to support the hull. Additionally disclosed is a container to transport NGH including a block of solid NGH and a skeletal structure to support the block. Further disclosed is a method of fabricating a marine vessel for transporting and storing natural gas hydrates (NGH), the method includes preparing a mold, placing a skin layer in the mold, assembling a skeletal structure in the mold, preparing a NGH slurry, and pouring into NGH slurry into the mold.

A system for distribution of hydrogen gas in a metal hydride reactor is disclosed. The system comprises a hydrogen distribution conduit positioned within a metal tube so as to define an annular space between the hydrogen distribution conduit and the outer metal tube. The hydrogen distribution conduit provides a flow passage for the hydrogen gas. A metal sponge matrix containing hydrogen-storing metal powder or hydrogen-storing alloy powder is filled in the annular space. The system provides a more uniform distribution of hydrogen across the particles of the hydrogen-storing metal/alloy powder, provides mechanical support to the hydrogen distribution conduit, improves the thermal conductivity of the powdered metal/alloy bed and reduces the size and production cost of the reactor.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a sidewall extending from the first end to the second end. The vessel further has a top, a bottom, at least one side, an internal surface, and an outlet fluidly coupled with the bottom. A scrubber tank is supported by the frame and fluidly connected to the a top of the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

A heat exchanger incorporates a metal hydride heat exchanger and mitigates the fluid mixing process, and thus greatly improves the heat transfer efficiency and heat recovery processes. The metal hydride heat exchanger has a container for the metal hydride that has a large aspect ratio. A plurality of high aspect container for the metal hydride may be coupled with a manifold.
