What kind of energy is hydrogen?

Hydrogen is a kind of clean energy. Hydrogen energy is recognized as clean energy and a new low-carbon and zero-carbon energy. In the 20th century, China, the United States, Japan, Canada and the European Union all made plans for the development of hydrogen energy, and China made various progress in the field of hydrogen energy. It is expected to become one of the leading countries in hydrogen energy technology and application in the near future, and it is also internationally recognized as the country most likely to take the lead in realizing the industrialization of hydrogen fuel cells and hydrogen energy vehicles.

Characteristics of hydrogen:

1, the lightest weight: in the standard state, when the density is 0.0899g/L and the temperature is -252.7℃, it can become a liquid; If the pressure increases to several hundred atmospheres, liquid hydrogen will become metallic hydrogen.

2. The thermal conductivity is the best: it is 10 times higher than that of most gases.

Abundant reserves: It is estimated that it accounts for 75% of the mass of the universe. It is mainly stored in the form of compounds in water, which is the most extensive substance on the earth. It is estimated that if all hydrogen in seawater is extracted, the total heat generated is 9000 times greater than that released by all fossil fuels on the earth.

4. Recovery: The only waste discharged by cars using hydrogen energy is water, so hydrogen can be decomposed again and recovered again.
