Green hydrogen, also called renewable hydrogen, is hydrogen obtained by using renewable energies in its production.Hydrogen is not a primary energy source but an energy carrier, it requires a chemical process for its production. Green hydrogen is generated by a chemical process known as electrolysis. This method uses electric power to break the water molecule, generating hydrogen and oxygen in the process. There are different electrolytic technologies, mainly divided into four types: conventional alkaline electrolysis, protonated polymer membrane electrolysis (PEM), anion exchange polymer membrane electrolysis (AEM) and solid state electrolysis (SOE).
Green hydrogen generation currently accounts for only 0.1% of overall hydrogen production. This way of obtaining green hydrogen would save the 830 million ton of CO2 per year that are generated when this gas is produced by fossil fuels. EDIBON is therefore firmly committed to the development and optimization of this technology with great potential for transforming the industrial sector.
