What is the history of Hydrogen gases?
Hydrogen was first discovered as a separate substance by Henry Cavendish in 1766. Cavendish accidentally discovered this gas while performing his experiments between mercury and acids.
Although, Henry Cavendish erroneously assumed that hydrogen is a compound of mercury at that time, he was able to accurately describe many properties of hydrogen. Antoine Lavoisier was the one who named this element and showed that people can make water from hydrogen and oxygen.
What do chemical composition, structure and properties of hydrogen gases like?
Natural state of hydrogen:
Natural hydrogen contains 1H isotope (protium) with the impurity of 2H stable isotope (deuterium D, plural) and a radioactive isotope type 3H (tritium T, trace).
Hydrogen is the most popular element in the universe. Its primary origin is water consisting of 2 atoms Hydrogen and 1 actom Oxygen (H2O). Hydrogen is also consisted in other sources such as most of organic substances, coal, fossil fuels and natural gases. Methane (CH4) is a fairly important source of hydrogen.
Physical properties of hydrogen gas:
- At standard temperature and pressure, hydrogen is a diatomic gas with the H2 molecular formula consisting of two hydrogen atoms.
- Hydrogen gases is Colorless, odorless, difficult to liquefy,flammable and boils at 20.27 K (-252.87 ° C) and melts at 14.02 K (-259.14 ° C).
- This gas slightly dissolve in water but dissolve much in organic solvents
Chemical properties:
- Hydrogen is a non-metallic element whose atomic number is 1 and hydrogen’s cubic atom is also equal to 1.
- Its electron configuration is in period 1, group IA. Hydrogen can react with most different chemical elements. It is a strong reducing agent at high temperatures.
Is hydrogen gas toxic?
Hydrogen is an extremely flammable gas, it reacts extremely strongly with chlorine and fluorine, creating folic acid hydrogen that can affect the lungs and other parts of the human body.
When mixed with oxygen or when an electric current goes through hydrogen gas will explode and catch fire.
However, hydrogen gases is colorless, tasteless and non-toxic, so you can safely use it, just be careful when letting it contact with other substances.
Hydrogen gas is quite flammable, to ensure safety, MIGCO does not recommend using hydrogen gases to pump bubbles or gas ports. Instead, customers should choose helium gases because it is inert, it is safer.

What is the Production of hydrogen like?
Hydrogen is generated from water and solar energy, so the hydrogen gases collected from solar energy is called solar hydrogen. Water and sunlight are endless sources on the planet.
Solar energy is the eternal natural source, about 3 × 1024 J / day or about 104 times the energy that the whole world consumes annually. Therefore, hydrogen generated from the solar energy is an infinite fuel source, people use this gas impartially through centuries. This energy is always safe for human beings without being depleted. As a result, there is not any energy crisis appearance and each nation’s energy independence is ensured.
there are currently two main production methods to get hydrogen gas from solar energy:
♦ Water electrolysis method thanks to solar power through solar panels..
♦ And the photoelectrochemical water splitting method thanks to the radiation energy level of sunlight and the photocatalytic catalyst.
H2O – H2 + 1/2O2
In a laboratory, hydrogen gas is usually prepared by the reaction between metals and acids:
Ví dụ: Zn + 2HCl → ZnCl2 + H2
In addition, hydrogen gas can be prepared in many different ways: passing steam through red hot coal (carbon), degradation of hydrocarbons by temperature, placing strong bases in solution with aluminum or demagnetizing dilute acids with metals (capable of repelling hydrogen from acids).Conventional commercial hydrogen production is from natural gas, which is also treated with hot steam. At high temperatures (700-1,100 ° C), water vapor reacts with methane to produce carbon monoxide and hydrogen.
CH4 + H2O → CO + 3 H2
– Production of hydrogen by electrolysis of a membrane solution
2NaCl + 2H2O → 2NaOH + H2 + Cl2
– Electrolysis water:
2H2O → 2H2 + O2
– Additional amount of hydrogen can be obtained from CO through the following water-gas reaction:
CO + H2O → CO2 + H2
The process of transporting and delivering hydrogen gas:
Depending on the quantity in need, customers can choose the corresponding type of hydrogen gas cylinder to serve their purpose.
Current popular capacity of hydrogen cylinders are 41L, 47L, and 50L with charge pressure of 150 bar or 200 bar. Your order will be transported and delivered in a safe truck by MIGCO staff
