An electrochemical heat transfer device utilizes an electrochemical hydrogen compressor to pump hydrogen into and out of a reservoir having a metal hydride forming alloy therein. The absorption of hydrogen by the metal hydride forming alloy is exothermic, produces heat, and the desorption of the hydrogen from the metal hydride forming alloy is endothermic and draws heat in. An electrochemical hydrogen compressor may be configured between to reservoirs and pump hydrogen back and forth to form a heat transfer device. A heat exchange device may be coupled with the reservoir or may comprise the outer surface of the reservoir to transfer heat to an object or to the surroundings. A closed loop may be configured having two reservoirs and one or two electrochemical hydrogen compressors to pump the hydrogen in a loop around the system.

Then, hydrogen gas is charged into the canister body, and a second weight of the canister body is recorded. Then, a hydrogen storage amount is calculated according to the first weight and the second weight. If the hydrogen storage amount reaches the predetermined value, the hydrogen storage container is produced.

A gas storage apparatus includes a foam body having a negative Poisson's ratio, and a gas impregnated in closed cells of the foam body, the gas having a pressure above atmospheric pressure. A method of making a gas storage apparatus includes providing a first body comprising a precursor material, and, while the first body is in an atmosphere including a gas, applying a stimulus to the precursor material, the stimulus causing the precursor material to form a closed-cell porous foam structure having a negative Poisson's ratio.

The disclosed hydrogen distribution system enables use of water, sewer, storm drain and other existing pipelines for local distribution. Hydrogen is produced from an energy source at a producing location. A safety pipe is located inside an existing pipeline configured to carry a first product and a hydrogen delivery line, configured to carry hydrogen, is placed inside the safety pipe such that a channel is formed between an exterior of the hydrogen delivery line and an interior of the safety pipe. Hydrogen is injected into the hydrogen delivery line and a sweeper gas is injected into the channel to purge any hydrogen that might be leaking from the hydrogen delivery line.
