The lightest element in the periodic table, hydrogen (H), is used for weather balloons, processing petroleum products, glass production, and heat-treating furnaces for steel production. As a highly flammable gas, Hydrogen is commonly used in a variety of chemical processes, such as hydrogen fuel cells to power cars and in fuel celled forklifts. Hydrogen’s popularity is increasing because it’s reliable, versatile, and can be produced in a variety of ways.
Hydrogen has only one proton and one electron, making it the simplest element and is considered a clean and renewable resource. It’s not toxic to human health, as no harmful byproducts are released into the atmosphere.
Hydrogen comes in a variety of “colors.” What this means exactly, is that hydrogen manufacturing methods of separating hydrogen from various compounds (water, ammonia, methane, etc.), and the emissions that result thereafter, are labeled as three main color distinctions: brown, green, and blue.
Brown hydrogen – which comprises 95% of hydrogen production – is the byproduct of fossil fuels. Steam reforming and gasification is the separation of hydrogen atoms from carbon atoms in either natural gas or coal production. During this process of gasification, carbon dioxide emissions are high.
Electrolysis is the process in which an electrical current is used to split water molecules into hydrogen and oxygen. When hydrogen is harvested, only oxygen is left over. The lack of Co2 emissions makes this production method green.
Blue hydrogen is the capture and storage of hydrogen during steam methane reformation, which causes some, but reduced, carbon dioxide emissions.
