Hydrogen (H2) is a colorless, odorless diatomic gas. The relative air density is 0.069, which is the lightest element. At normal temperature and pressure, gaseous hydrogen does not react with most substances. However, at higher pressures and moderate temperatures, hydrogen reacts with many hydrocarbon materials. Hydrogen reacts with oxygen and other gases, many metals and metal oxides at normal pressures and temperatures, and is a highly efficient reducing agent. The normal boiling point of liquid hydrogen is -252.8 ° C, which is the lowest temperature gas other than helium. However, this property is rarely used because it is highly flammable. Hydrogen is a gaseous fuel that burns with a transparent flame that is difficult to see and water is the only combustion product.
Hydrogen has played an important role in many industrial processes for many years. Almost half of the world's hydrogen production is used in the chemical industry to produce ammonia and methanol. A large amount of hydrogen is also used in the metal processing, glass manufacturing, electronics and food industries to reduce the large emissions of desulfurized gasoline and diesel from internal combustion engines and refineries. This process requires the use of hydrogen - in a reactor where hydrogen is combined with a sulfur feed to produce hydrogen sulfide. After the sulfur is separated again, it is used for vulcanization of rubber or processing into fertilizer.
Hydrogen is the most common element in nature. Unlike fossil fuels such as crude oil and natural gas, hydrogen is never depleted. Like electricity, hydrogen is an energy carrier, not an energy source, so it must be obtained through production. Even so, hydrogen has many advantages and has enormous potential to replace fossil fuels. For example, stored hydrogen can be used directly as a fuel or to produce electricity. Even with the current natural gas steam reforming process to produce hydrogen, this has helped reduce carbon emissions from the entire value chain of the mine to the wheel. Hydrogen fuel vehicles can reduce carbon emissions by up to 30% compared to modern diesel vehicles.
Hydrogen is an environmentally friendly energy carrier. It is an ideal medium for storing renewable energy sources such as wind and solar energy, which are inherently volatile. Wind can't always exist, and there will be no sustained wind speed even if it exists. Similarly, solar energy only exists during the day, and in mild climates, it only has enough energy in the summer. Need to achieve on-demand from the above renewable energy sources, depending on the effective energy storage solution. Hydrogen can play a key role in it because energy from wind and solar power plants can power the electrolysis of water. Hydrogen can be compressed or liquefied while being stored for the length of time required. When energy is needed, hydrogen can be burned to produce zero-emission electricity, or directly converted to electricity by a fuel cell.
