Hydrogen Energy
In the face of an environmental crisis, the world has taken action to reduce greenhouse gas emissions, the main problem of global warming. Currently, it declares the end of the fossil fuel era, the world's main energy source, and is striving to enter the era of renewable and eco-friendly energy. Hydrogen energy is one of the ultimate clean energy sources in the future, replacing oil or coal, as an energy source that stores and uses energy in the form of hydrogen. Water, which is a raw material for hydrogen energy, exists abundantly on Earth, and even when hydrogen is burned, it combines with oxygen and turns into a very small amount of nitrogen and water, so there is no fear of environmental pollution caused by pollutants.
Hydrogen not only reduces greenhouse gas emissions but also has stronger potential than other eco-friendly energy in terms of economic utility. Assuming that hydrogen energy is activated by the continuous development of related technologies, the Hydrogen Committee predicted that hydrogen will account for 18% of the world's energy demand by 2050.
In addition, it is expected to create a related market worth about $2.5 trillion and create 30 million jobs worldwide. In other words, hydrogen energy can take practical benefits as well as environmental purification effects.
If the hydrogen electric vehicle sector grows as planned, hydrogen is expected to replace about 20 million barrels (about 3.2 billion liters) of oil per day by 2050. Currently used hydrogen are by-product hydrogen (hydrogen produced as a by-product in the petrochemical industry) and extracted hydrogen (hydrogen extracted from liquefied natural gas), and it is true that some greenhouse gases are emitted during the production process. However, if the water electrolysis method (a method of obtaining hydrogen by electrolyzing water) that does not emit greenhouse gases becomes common due to advanced technology, the reduction in exhaust gas from the use of hydrogen energy is expected to reach about 440 million tons.
