12 Facts About Hydrogen production

Hydrogen production is the family of industrial methods for generating hydrogen gas.

Hydrogen production separation occurs in one step via flow through a molten metal catalyst in a "bubble column".

Hydrogen production can be separated from other impurities by the pressure-swing adsorption process.

Hydrogen production is not only the cleanest fuel but widely used in a number of industries, especially fertilizer, petrochemical and food ones.

Fermentative hydrogen production is the fermentative conversion of organic substrate to biohydrogen manifested by a diverse group of bacteria using multi enzyme systems involving three steps similar to anaerobic conversion.

Fermentative hydrogen production can be done using direct biophotolysis by green algae, indirect biophotolysis by cyanobacteria, photo-fermentation by anaerobic photosynthetic bacteria and dark fermentation by anaerobic fermentative bacteria.

For example, studies on hydrogen production using H salinarium, an anaerobic photosynthetic bacteria, coupled to a hydrogenase donor like E coli, are reported in literature.

Hydrogen production produced using the newer, non-polluting technology methane pyrolysis is often referred to as turquoise hydrogen.

Hydrogen production produced from renewable energy sources is often referred to as green hydrogen.

Hydrogen production fuel, when produced by renewable sources of energy like wind or solar power, is a renewable fuel.

Hydrogen production produced from nuclear energy via electrolysis is sometimes viewed as a subset of green hydrogen, but can be referred to as pink hydrogen.

Hydrogen production is used for the conversion of heavy petroleum fractions into lighter ones via hydrocracking.
