The reason for the low efficiency of hydrogen transportation is that the density of hydrogen storage is too low.

At present, various methods of hydrogen transmission are actually transporting stored hydrogen. If the hydrogen storage density increases, the efficiency of hydrogen delivery will naturally increase.

Scientists now boldly imagine the co-transmission of hydrogen and electricity, which is expected to greatly increase the efficiency of energy transmission. The idea is that in a large-scale solar power center, people first use photovoltaic photovoltaic or solar thermal power generation to obtain a large amount of electricity, and then use the clean electricity obtained from these renewable energy sources to electrolyze water to produce hydrogen, and then liquefy hydrogen to obtain liquid hydrogen. Use multi-layer coaxial cables to transport liquid hydrogen and electricity at the same time.

The center of the cable transports liquid hydrogen while using the extremely low temperature of the liquid hydrogen to keep the outer metal in a superconducting state. Because there is no resistance, no heat is generated when the current passes through it. Large-scale transmission of electricity can be achieved, and the loss of power transmission is greatly reduced.

The outermost layer of the coaxial cable is a heat-insulating and insulating protective layer. To develop solar power plants in the deserts of Northwest my country to produce liquid hydrogen and electricity at the same time, and then transport them to the eastern coastal areas of my country.

Experts predict that once this idea is realized, it will greatly change country’s energy pattern.
