The calorific value of hydrogen is 1.27kJ/g.
The combustion product of hydrogen is water, which produces no harmful pollutants, and is therefore considered a clean energy source. Hydrogen has a very low density at room temperature and pressure, which is about 0.08988kg/m? at standard temperature and pressure. Because of its low density, hydrogen has some difficulties in storage and transportation.
Hydrogen has a high calorific value and burns quickly, so it is widely used in industrial and civil fields. In the industrial field, hydrogen is used in the synthesis of ammonia, the production of formaldehyde, oil refining, metal smelting and other fields. In the civilian field, hydrogen is used in fuel cell vehicles, portable electronic equipment, aerospace and other fields.
Hydrogen can also be used for energy storage and power generation. Since hydrogen can be stored in gaseous or liquid form, it can be stored and released when needed, thus solving the problem of intermittency in renewable energy generation. Hydrogen can also be used in fuel cell power generation, which produces no emissions or noise and can be adapted to different power needs by varying the size of the fuel cell stack.
Uses of hydrogen:
In the industrial field, hydrogen is widely used in the synthesis of ammonia, the production of formaldehyde, oil refining, metal smelting and other fields. In addition, hydrogen can be used to produce high value-added chemicals, such as methanol and ethylene glycol.
In the field of energy, hydrogen is a clean energy source with the advantages of high energy density and zero emission. Hydrogen can be used in fuel cell vehicles, portable electronic devices, aerospace and other fields, as well as being a sustainable energy source.
In the medical field, hydrogen is used to treat a number of diseases, such as inflammation-related diseases, cardiovascular and cerebrovascular diseases, liver diseases, and lung diseases. Studies have shown that hydrogen can reduce inflammatory reactions, regulate the function of the immune system, and have a protective effect on several systems such as the nervous, respiratory, digestive, and endocrine systems.
