What is Hydrogen?
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications. It can be used in cars, in houses, for portable power, and in many more applications.
Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources.
Today, hydrogen fuel can be produced through several methods. The most common methods today are natural gas reforming (a thermal process), and electrolysis. Other methods include solar-driven and biological processes. Read more from the U.S. Department of Energy’s website.

The Hydrogen ‘Spectrum’
Green hydrogen is hydrogen produced with no harmful greenhouse gas emissions. Green hydrogen is made by using clean electricity from surplus renewable energy sources, such as solar or wind power, to electrolyze water. Electrolyzers use an electrochemical reaction to split water into its components of hydrogen and oxygen, emitting zero carbon dioxide in the process.
Green hydrogen currently makes up a small percentage of the overall hydrogen spectrum, because production is expensive. Just as energy from wind power has reduced in price, green hydrogen will come down in price as it becomes more common.
Pink hydrogen is generated through electrolysis like green hydrogen, however is powered by nuclear energy. Nuclear-produced hydrogen can also be referred to as purple hydrogen or red hydrogen.
Hydrogen made from black coal or lignite (brown coal) through the process of ‘gasification’ is sometimes called black or brown hydrogen interchangeably. It is similar to gray hydrogen, because the carbon dioxide byproduct is not captured, so it is the most carbon intensive form of producing hydrogen.
Yellow hydrogen is a relatively new phrase for hydrogen made through electrolysis using solar power.
