Hydrogen gas has a variety of uses, but two notable applications are:
-
Fuel Cells: Hydrogen is used in fuel cells to generate electricity. In this process, hydrogen reacts with oxygen in a chemical reaction that produces electricity, water, and heat, making it a clean energy source for vehicles and stationary power generation.
-
Industrial Processes: Hydrogen is widely used in various industrial processes, including the production of ammonia for fertilizers through the Haber process, and in refining petroleum to remove sulfur impurities, a process known as hydrocracking.
