Hydrogen telluride is the inorganic compound with the formula H 2 Te.A hydrogen chalcogenide and the simplest hydride of tellurium, it is a colorless gas.Although unstable in ambient air, the gas can exist long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations.
Compressed hydrogen tube trailer. Hydrogen tube trailers are semi-trailers that consist of 4 to 36 cluster high-pressure hydrogen tanks varying in length from 20 feet (6.10 m) for small tubes to 53 feet (16.15 m) on jumbo tube trailers. They are part of the hydrogen highway [1] and usually precede a local hydrogen station.
The −2 oxidation state is exhibited in binary compounds with many metals, such as zinc telluride, ZnTe, produced by heating tellurium with zinc. [2] Decomposition of ZnTe with hydrochloric acid yields hydrogen telluride (H 2 Te), a highly unstable analogue of the other chalcogen hydrides, H 2 O, H 2 S and H 2 Se:
Hydrogen, being the lightest existing gas (7% the density of air, 0.08988 g/L at STP), seems to be the most appropriate gas for lifting.It can be easily produced in large quantities, for example with the water-gas shift reaction or electrolysis, but hydrogen has several disadvantages:
Compressed hydrogen is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology.
Cascade storage is used at compressed natural gas (CNG) fueling stations. Typically three CNG tanks will be used, and a vehicle will first be fueled from one of them, which will result in an incomplete fill, perhaps to 2000 psig for a 3000 psig tank. The second and third tanks will bring the vehicle's tank closer to 3000 psi.
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...
A liquid hydrogen tank car, also called liquid hydrogen tank wagon or liquid hydrogen tanker wagon is a railroad tank car designed to carry cryogenic liquid hydrogen (LH 2). LH 2 tank cars with a capacity of 17,000 pounds (7,711 kg) are used for transcontinental transport.
