What is a hydrogen tank?
The hydrogen tank is a canister used to store compressed hydrogen. Type IV hydrogen tanks are an integral part of vehicles powered by hydrogen. Such vehicles can be added to hydrogen stations. Compressed hydrogen is used as an alternative source of fuel to oil and other fossil fuels. As a result, gas storage was an important part of the development of technology. Scientists hope to use liquid hydrogen as a source of fuel to explore space. The problem of storing liquid hydrogen is that it has a boiling point of -423,188 degrees Fahrenheit (-252,882 degrees Celsius). In order to maintain liquid, hydrogen must be stored in extremely cold conditions. This requires cryogenic, uses a large amount of energy and is expensive to produce.
The storage of gaseous hydrogen is much easier. The hydrogen tank works by storing compressed hydrogen under pressure. The vehicle requires hydrogen to be compressed to 350 and 700 bar or 5,000 and 10,000 dogs. Bar is a metric measure based on standard atmospherethe pressure found on the sea level. Dogs are short on a pound per square inch and it is an imperial measure based on the amount of pressure exerted by one pound per square inch.
There are four basic types of hydrogen tank. They differ from the point of view of what they are made of and what pressures they can match. They tend to use metals such as magnesium hydride or sodium hydride. Several types are mixed with composites or in the case of Model IV is composed in the assembly.
Type I is a metal tank. The aluminum variety has a working pressure of 175 bar or 2,538 dogs. The steel variety works at 200 bar or 2,900 dogs.
type II tanks are made of metal surrounded by roller fiber. The aluminum tank operates at 263 bar or 3 814 dogs. The steel carbon tank has a functional pressure of 299 bar, or 4 336 dogs.
Composite materials surrounding the metal insert of type III folding. CompositesThey are made of materials such as aramid and glass fiber. The glass fiber model has a normal pressure of 305 bar or 4,423 psi, while the Aramid version works on 438 bar or 6 352.
type IV hydrogen tank is a rotary moldinate tank made of composite materials such as a carbon fiber with a polymer insert. They have a working pressure of 661 bar or 9 586 dogs. Type IV is most common in vehicles such as cars and trucks.
All hydrogen tanks require extensive testing to ensure that they are safe for use. The hydrogen tank is tested in four ways. The breast test uses twice the normal working pressure to find out when the tank breaks, while the test pressure test explores how the tank is compared with 1.5 times normal pressure. The tank has been tested for long -term fatigue and leaks.
