Answer:
Natural Gas Reforming/Gasification: Synthesis gas—a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide—is created by reacting natural gas with high-temperature steam. Or, Electrolysis: An electric current splits water into hydrogen and oxygen.
Hydrogen can be stored physically as either a gas or liquid. It typically requires high-pressure tanks (350-700 bar tank pressure). Another possibility is the chemical storage of hydrogen, whereby it is stored on the surface of solids (by adsorption) or within solids (by absorption).
Step-by-step explanation:
Natural gas reforming is an advanced and mature production process that builds upon the existing natural gas pipeline delivery infrastructure. Today, 95% of the hydrogen produced in the United States is made by natural gas reforming in large central plants.
Gasification is a process that converts organic or fossil-based carbonaceous materials at high temperatures (>700°C), without combustion, with a controlled amount of oxygen and/or steam into carbon monoxide, hydrogen, and carbon dioxide.
Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer.
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H 2. It is colorless, odorless, tasteless, non-toxic, and highly combustible.
