In recent years, hydrogen has been shown to be one of the alternatives for decarbonising both industrial and domestic activity. Currently, hydrogen is produced through chemical processes using fossil fuels, causing this production to generate GHG emissions. There are several alternatives to fossil or non-renewable hydrogen production such as the use of electrolysers, photocatalysis reactors, hydrogen production by microorganisms or adding carbon capture and storage (CCS) to non-renewable hydrogen generation. It is estimated that renewable, or low-emission, hydrogen can avoid the generation...
