A British study has found that if hydrogen gas were to enter the air in its original state, it would have 11 times more warming effect than carbon dioxide.
This discovery is important because alternative sources of energy include hydrogen. It chemically reacts with the oxygen in the air to form water and releases pollution-free energy.
It should be noted that hydrogen is widely used in petroleum refineries, metallurgy, fertilizer manufacturing and food products. The use of hydrogen in the pursuit of clean energy is also increasing. It is hoped that in the next ten to twenty years, petrol pumps and CNG stations will be replaced by hydrogen pumps where incoming vehicles will be filled with hydrogen fuel. In that case, there would be a risk of pure hydrogen being released into the air, but at the moment we do not know what effect this could have on the atmosphere and global warming. The study , conducted in collaboration with various British agencies, found that pure hydrogen has 11 times more heat-absorbing capacity than carbon dioxide. However, unlike carbon dioxide, it does not directly heat the atmosphere by absorbing heat, but by helping the various greenhouse gases and airborne substances that cause heat buildup to stay in the air longer, or to absorb heat in them. Increases heat while increasing the capacity of. For example, because of hydrogen, methane gas can stay in the air longer. By the way, the capacity of methane to heat the atmosphere is 80 times greater than that of carbon dioxide, but hydroxyl radicals in the air chemically react with methane in a very short time to break it down and make it harmless and thus the effect of methane in global warming is very low. Is left Pure hydrogen is much more potent than methane in terms of chemical reactions to hydroxyl radicals.
That is, if methane and hydrogen were present in the air together, hydroxyl radicals would preferably chemically react with hydrogen, while methane would have very little chance of a chemical reaction. This will allow the methane to stay in the air longer and have a warmer climate. Considering this and other similar factors, British experts have calculated that the role of hydrogen in global warming may be 11 times or more than that of carbon dioxide, which is undoubtedly a matter of concern.
This information will provide significant guidance in formulating environmental policies regarding the use of hydrogen.
