Liquid Hydrogen vs Gasoline Energy Density
"Comparison of Energy Density of Hydrogen Liquid and Gasoline"
Today's discussion of hydrogen liquid and gasoline, the difference in energy density is related to transportation. Gasoline has been a source of power for a long time, and everyone is used to it. Its energy density is indispensable for carrying people in the past. The energy contained in each liter of gasoline is about 34.20 trillion joules, which can make vehicles travel through roads, carry people, and travel freely in all directions.
However, hydrogen liquid is a new energy. The energy density of liquid hydrogen, when it comes to mass, can reach 142 trillion joules per kilogram, far exceeding that of gasoline. This is quite advantageous in mass-sensitive areas such as aviation. In terms of aircraft, if liquid hydrogen is used as energy, it can reduce the weight of the fuselage, increase the range of flight, and drive straight at high altitudes, which is more smooth.
However, liquid hydrogen also has difficulties. Its production is not easy, it requires high technology and huge expenses. And storage is difficult, it must be extremely low temperature to maintain liquid state, and the equipment requirements are very demanding. Gasoline is not the case. Its refining method is mature, storage and transportation are convenient, and it is well adapted to the current facility system.
Therefore, weighing the energy density of the two, although liquid hydrogen has great potential and great promise, gasoline has a deep foundation, and is still the mainstream of power in today's situation. To widely use liquid hydrogen, it is still necessary to advance technology and make it good before it can gradually replace gasoline, become a new source of power, promote the transformation of transportation, and bring about the prosperity of all things.
