Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe.Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans. But while...

Hydrogenation is a chemical reaction between molecular hydrogen and an element or compound, ordinarily in the presence of a catalyst. The reaction may be one in which hydrogen simply adds to a double or triple bond connecting two atoms in the structure of the molecule or one in which the addi...

When it comes to power, hydrogen is one of the most energy dense fuels. One kilogram of hydrogen gas generates the same amount of energy as almost three kilograms of gasoline, making the chemical element a highly efficient fuel source. With water and heat as its only by products, hydr...
Hydrogen is the lightest element in the universe and the most abundant, so on paper, hydrogen fuel has a lot going for it. Although it rarely exists on its own on Earth, it can be produced using clean energy to split essentially inexhaustible water molec

Verb1.hydrogenate- combine or treat with or expose to hydrogen; add hydrogen to the molecule of (an unsaturated organic compound) alter,change,modify- cause to change; make different; cause a transformation; "The advent of the automobile may have altered the growth pattern of the city"; "Th...
What is renewable hydrogen? Renewable hydrogen is hydrogen derived from water. It’s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes from renewabl...
Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Hydrogenation is not thermodynamically favorable at ordinary temperatures, so a catalyst is needed. Usually this catalyst is a metal. Examples of hydrogenated products include margarine, mineral turpentine, and aniline. ...
