Why is hydrogen energy the outlet of future energy

current news 2022-01-18 1076

Hydrogen, the oldest element in the universe, existed before the sun; Hydrogen is also the most abundant element in the universe, making up 88.6 percent of the atoms in the universe. It's not just hydrogen in water, it's the source of energy for the sun, and it could be the main source of energy for the earth in the future.

The usual elemental form of hydrogen is hydrogen, and hydrogen has three very competitive advantages as an energy source:

1. Abundant reserves

From the mass composition of chemical elements, hydrogen occupies about 3/4 of the mass of the universe. On Earth they occur mainly as compounds: they are found in water, hydrocarbons and other organic matter.

Take seawater for example, the total volume of the ocean is about 1.37 billion cubic meters. If all the hydrogen in seawater is extracted, there is about 1.4×1017 T, and the heat generated is about 9000 times that of fossil fuels on earth.

2. High energy density

Energy density is the amount of energy stored in a given amount of space or mass of matter.

Throughout the history of human energy use, from wood and coal to oil and natural gas, the main thread is the increasing energy density and hydrogen/carbon ratio (H/C ratio). And hydrogen as an ideal new energy, it shows the "a ride of dust" high energy density (and without C), per kilogram H₂ combustion can emit 121 ~ 143 kJ of heat, about 3 times gasoline, 3.9 times alcohol, 4.5 times coke.

3. Clean and carbon-free

Hydrogen combustion only produces water, no emissions of carbon and pollutants, and no fine dust. It is a non-toxic and harmless clean energy.
