Hydrogen

Hydrogen is a chemical element that is classified under the supply class Gases: Compressed And Liquefied in the supply group Chemicals And Chemical Products. It is the lightest and most abundant element in the universe. Hydrogen is commonly used in various industries for a wide range of applications.

Some common uses of hydrogen include:

1. Industrial Processes: Hydrogen is used in the production of ammonia, methanol, and other chemicals. It is also used in the petroleum refining industry to remove impurities from fuels.

2. Energy Storage: Hydrogen can be used as a clean and efficient energy carrier. It can be stored and transported to be used as a fuel for power generation or as a feedstock for fuel cells.

3. Hydrogen Fuel Cells: Hydrogen fuel cells convert the chemical energy of hydrogen into electrical energy. They are used in transportation, such as fuel cell vehicles, and in stationary power applications.

4. Metal Production: Hydrogen is used in the production of metals like steel and titanium. It is used as a reducing agent to remove oxygen from metal ores during the smelting process.

5. Food Processing: Hydrogen is used in the food industry for various purposes, including hydrogenation of oils and fats, as a food preservative, and in the production of carbonated beverages.

It is important to handle hydrogen with caution as it is highly flammable and can form explosive mixtures with air. Safety measures should be followed when storing, handling, and transporting hydrogen.

Please note that this is just a brief overview of the uses of hydrogen from the supply class Gases: Compressed And Liquefied in the supply group Chemicals And Chemical Products. There may be other specific applications depending on the industry and context.
