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 for small tubes to on jumbo tube trailers. They are part of the hydrogen highway and usually precede a local hydrogen station. Types Modular tube trailer Older tube trailers made of steel (Type I) usually carry about per load, while new and more efficient composite trailers (Type IV) made of carbon fiber make it possible to carry up to per load. Modular tube trailers range from 8 to 54 tubes. Intermediate trailer Intermediate tubes are assembled in banks of 5 tubes in lengths of and provide mobile or stationary storage. Jumbo tube trailer A trailer with 10 tubes and a chassis, operating with pressures in excess of . Composite tube trailers As of 2012, the US Department of Transportation (DOT) started to award Special Permits (SP) to different manufactures to produce Type IV Hydrogen trailers in the US. The US is the current leader in Composite tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-trailer
A semi-trailer is a trailer (vehicle), trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a ''semi-trailer truck'' (also known simply as a "semi-trailer", "tractor trailer", or "semi" in the United States). A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly (trailer), dolly, or the B-Train, tail of another trailer. The semi-trailer's weight is semi-supported (half-supported) by its own wheels, at the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than Trailer (vehicle)#Full, full trailers, which have both front and rear axles. Ease of backing i ...

Hydrogen Tank
A hydrogen infrastructure is the infrastructure of points of hydrogen production, truck and pipeline transport, and hydrogen stations for the distribution and sale of hydrogen fuel, and thus a crucial prerequisite before a successful commercialization of fuel cell technology. Hydrogen stations which are not situated near a hydrogen pipeline get supply via hydrogen tanks, Compressed hydrogen tube trailer, compressed hydrogen tube trailers, Liquid hydrogen trailer, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production. Pipelines are the cheapest way to move hydrogen over long distances compared to other options. Hydrogen gas piping is routine in large oil-refineries, because hydrogen is used to Hydrocracking, hydrocrack fuels from crude oil. The IEA recommends existing industrial ports be used for production and natural gas pipelines for transport, international co-operation and shipping.

Hydrogen Economy
The hydrogen economy is an umbrella term for the roles hydrogen can play alongside low-carbon electricity to reduce emissions of greenhouse gases. The aim is to reduce emissions where cheaper and more energy-efficient clean solutions are not available. In this context, ''hydrogen economy'' encompasses the production of hydrogen and the use of hydrogen in ways that contribute to phasing-out fossil fuels and limiting climate change. Hydrogen can be produced by several means. Most hydrogen produced today is ''gray hydrogen'', made from natural gas through steam methane reforming (SMR). This process accounted for 1.8% of global greenhouse gas emissions in 2021.Greenhouse gas emissions totalled 49.3 Gigatonnes CO2e in 2021. ''Low-carbon hydrogen'', which is made using SMR with carbon capture and storage ('' blue hydrogen''), or through electrolysis of water using renewable power ('' green hydrogen''), accounted for less than 1% of production. Virtually all of the 100 million tonnes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liquid Hydrogen Tank Car
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 (LH2). LH2 tank cars with a capacity of are used for transcontinental transport. Design The pressure within the tank is or lower with a temperature below 20.27 K () and a boil-off rate of 0.3% to 0.6% per day The tank is double walled like a vacuum flask with multi-layer insulation, with the valves and fittings enclosed in a cabinet at the lower side or end of the car. Classes Cryogenic liquid tank cars in the US are classified as follows: * DOT-113 tank cars (Cryogenic liquid tank cars) * AAR-204W tank cars (Cryogenic liquid tank cars) * AAR-204XT (Inside boxcar) See also * Association of American Railroads (AAR) * Compressed hydrogen tube trailer * Hydra (''Starlight Express'' character) *Hydrogen economy *Hydrogen infrastructure * Liquid hydrogen tanktainer * Liquid hydrogen trailer * United States Departmen ...

Liquid Hydrogen Tanktainer
A liquid hydrogen tank-tainer, also known as a liquid hydrogen tank container, is a specialized type of container designed to carry cryogenic liquid hydrogen (LH2) on standard intermodal equipment. The tank is held within a box-shaped frame the same size and shape as a container. Size and volume Liquid hydrogen tanktainers are referenced by their size or volume capacity, generally an ISO container.

Liquid Hydrogen Trailer
A liquid-hydrogen trailer is a trailer designed to carry cryogenic liquid hydrogen (LH2) on roads being pulled by a powered vehicle. The largest such vehicles are similar to railroad tanktainers which are also designed to carry liquefied loads. Liquid-hydrogen trailers tend to be large; they are insulated. Some are semi-trailers. History The U-1 semi-trailer was a liquid-hydrogen trailer designed in the 1950s to carry cryogenic liquid hydrogen (LH2) on roads being pulled by a powered vehicle. It was constructed by the Cambridge Corporation and had a capacity of with a hydrogen loss rate of approximately 2 percent per day. The U-1 was a single-axle semi-trailer. The specifications for its successor the U-2, a double axle semi-trailer, were issued on 15 March 1957. Size and volume Liquid hydrogen trailers are referenced by their size or volume capacity. Liquid-hydrogen trailers typically have capacities ranging from gross volume. See also * Compressed-hydrogen tube t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Storage
Several methods exist for storing hydrogen. These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of ammonia. For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H2: it boils around 20.268 K (−252.882 °C or −423.188 °F). Achieving such low temperatures requires expending significant energy. Although molecular hydrogen has very high energy density on a mass basis, partly because of its low molecular weight, as a gas at ambient conditions it has very low energy density by volume. If it is to be used as fuel stored on board a vehic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
