Green Hydrogen
Production Solutions
Green hydrogen refers to hydrogen produced using renewable energy sources, such as solar or wind power, through a process called electrolysis.
Green Hydrogen Production
Hydrogen production by electrolysis generally takes place in 3 steps;
Electrolysis
Splitting water into its components hydrogen and oxygen in the electrolyzer,
Lye Collection
Collection of electrolyte alkali residues in the resulting hydrogen gas via gas-lye treater and feeding electrolyte back to the electrolyzer,
Purification
The high-purity hydrogen is then ready for direct use or storage for later use.

Purification of Hydrogen
Hydrogen purification is an important step in the hydrogen production process, especially when the end-use requires high purity levels, such as in fuel cells for electric vehicles or in certain industrial processes. The purity of hydrogen affects its efficiency and performance, making purification technologies an essential aspect of the hydrogen supply chain.
Hydrogen Purification Technologies
Industrial hydrogen purification typically involves technologies like Pressure Swing Adsorption (PSA), Membrane Separation, and Cryogenic Distillation. PSA is widely used for its efficiency in separating hydrogen from other gases in a mixture, utilizing materials that adsorb impurities at high pressures. Membrane Separation employs semi-permeable membranes to selectively allow hydrogen to pass through, leaving impurities behind. Cryogenic Distillation, though less common, is used in scenarios requiring extremely high purity levels, involving the cooling of gas mixtures to very low temperatures to separate components based on their boiling points.
