Glossary

B:

Blue Hydrogen: Hydrogen produced with CO2 emissions but the CO2 could be captured and sequestered (stored permanently)

C:

Cryogenics: The production and behavior of materials at temperatures <80k

D:

Deflagration: Propagation of a combustion zone at a speed less than the speed of sound in the unreacted medium. Deflagration burns outward radially and requires a fuel to continue.

Detonation: Propagation of a combustion zone at a speed greater than the speed of sound in the unreacted medium. More commonly associated with the term “explode”.

G:

Green Hydrogen: Hydrogen produced without CO2 emissions from clean and renewable electricity and water or biomass and algae.

Gray Hydrogen: Hydrogen produced with CO2 emissions (typically through steam methane reformation

H:

Hydrogen: Symbol H on the periodic table, it is the lightest element with an atomic mass of 1. It is the most abundant element in the universe and the HYPER lab seeks to further understand how it can be applied for energy research.

Hydrogen Fuel Cell: A device that generates electrical power through the chemical reaction of Hydrogen and Oxygen gas which results in the production of water.
