Energy Density Hydrogen vs Gasoline
Nowadays, there are those who discuss the energy density of hydrogen and gasoline. Hydrogen has the cleanest properties and different energy storage. In terms of unit mass, the energy density of hydrogen is quite high, and the energy per kilogram is far better than that of gasoline. Gasoline, the commonly used fuel in the world, has been around for a long time, but its energy density is higher than that of hydrogen in terms of mass.
Looking at the energy storage of hydrogen, if it is based on chemical energy, its chemical bond energy is unique, and between decomposition and combination, it can release great energy. And the product of hydrogen combustion is only water, which is absolutely pollution-free, which is the best for environmental protection. Gasoline combustion has carbon dioxide, nitrogen oxides, etc., which are harmful to the environment.
However, the application of hydrogen also has difficulties. Its storage and transportation are not easy, and special containers are required to maintain its high pressure and low temperature state to prevent leakage. Gasoline is not the case. It can be stored in ordinary containers, and the convenience of transportation is well known to everyone.
When it comes to energy density, hydrogen is inherently excellent, but it is widely used. The technology is difficult to break, and the cost is reduced. Although the energy density of gasoline is inferior to that of hydrogen, it is familiar with its use and has a complete foundation. It is difficult to replace it for a while. It is to weigh the two, and to find a long-term strategy, to seek technological progress, to hope for the change of energy, and to achieve an efficient and clean environment.
