Main Application of Hydrogen

Energy and the environment are the most important issues involved in the sustainable development of human society in the future.At present, most of the world's energy demand comes from fossil fuels, which will eventually lead to the depletion of fossil fuels, and their use will also lead to serious environmental pollution.Therefore, the development and utilization of sustainable and pollution-free non-fossil energy is an inevitable trend of future energy development.

Hydrogen is used in a wide range of fields, of which the largest amount is used as an important petrochemical raw material for the production of synthetic ammonia, methanol, and hydrogenation reactions in petroleum refining processes.In addition, it is also used in electronic industry, metallurgical industry, food processing, float glass, fine chemical synthesis, aerospace industry and other fields.

In the process of petroleum refining, the hydrocracking and hydrofining process of petroleum products need to use a large amount of hydrogen as a reaction raw material;In addition, hydrogen is mainly used as a reducing gas in the electronics industry, metallurgical industry, float glass and other industries;It is used as fuel in the electronics industry; liquid hydrogen is mainly used in the aerospace field as the main fuel for rocket propulsion.

In addition to the above conventional uses, more and more scientific research institutions are focusing on the development and utilization of hydrogen energy.Fuel cells using hydrogen as energy have become a key research topic worldwide.Since the late 1980s, due to the increasing pollution of vehicle exhaust, countries around the world have been scrambling to research and develop "zero-emission" fuel cell electric vehicles (FCEVs).Among them, the clean and environment-friendly proton membrane fuel cell (PEMFC) vehicle is recognized as the best choice to replace the traditional internal combustion engine vehicle.Due to new developments in fuel cell technology, hydrogen presents an extremely broad potential market as a fuel for fuel cells.
