What's the difference between green and blue hydrogen?

Green hydrogen is produced using electrolysis of water, and blue hydrogen utilizes natural gas. Green hydrogen represents a major opportunity for governments and private business to harness a valuable, sustainable energy resource in the coming decades.

Can H2 exist?

Hydrogen, most abundant in the universe, is the chemical element with atomic number 1, and an atomic mass of 1.00794 amu, the lightest of all known elements. It exists as a diatomic gas (H2). Accordingly, what are oxygen atoms? Oxygen is represented by the chemical symbol O. In the air, oxygen exists mostly as molecules each made up of two atoms (O2), although small amounts of ozone (O3), in which three atoms of oxygen make up each molecule, are present in the atmosphere.

Where does hydrogen come from in the universe?

Hydrogen is found almost everywhere in the universe. It occurs between and within stars, and in the enormous gas and dust clouds that exist throughout interstellar space. Scientists have known since the 1970s that bonds between hydrogen atoms form on the very cold surface of interstellar dust grains. Correspondingly, is hydrogen better than electric? Depending on the model, they can boast a well-to-wheel efficiency of around 70 to 80 per cent. By comparison, a hydrogen fuel cell-powered electric vehicle (FCEV) is positively parsimonious, with an overall efficiency of somewhere around 30 to 35 per cent. The difference is in how the two process electricity.

You can also ask is hydrogen the future?

Clean hydrogen is touted as the future fuel of the EU, promising to deliver an abundance of carbon-neutral energy by 2030. It will power long haul freight vehicles, airplanes, steel production and domestic heating, proponents say.
