Hydrogen Production: Electrolysis | Department of Energy

Electrolysis is a leading hydrogen production pathway to achieve the Hydrogen Energy Earthshot goal of reducing the cost of clean hydrogen by 80% to $1 per 1 kilogram in 1 decade ("1 1 1"). Hydrogen produced via electrolysis can result in zero greenhouse gas emissions, depending on the source of the electricity used.

Hydrogen

Hydrogen is produced on a commercial basis today – it is used as a feedstock in the chemical industry and in refineries, as part of a mix of gases in steel production, and in heat and power generation. Global production stands at around 75 MtH2/yr as pure hydrogen and an additional 45 MtH2/yr as part of a mix of gases.

A New Type of Material for the Recovery of Hydrogen from Gas Mixtures

Molecular gas works: p-tert-Butylcalix[4]arene crystals possess large interstitial cavities when grown by sublimation and, although nonporous, are able to absorb and retain gases such as O 2, N 2, and CO 2 under near-ambient conditions. H 2 is not retained and thus the material can be used to effect the separation of H 2 from gas …

Natural gas

Natural gas. Natural gas (also called fossil gas, methane gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (97%) [1] in addition to various smaller amounts of other higher alkanes. Traces of carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. [2]
