The next step of the global energy transition will be based on the hydrogen economy.

Green hydrogen is hydrogen that is produced using renewable energy sources rather than fossil fuels. Hydrogen is a versatile energy carrier that can be used in a wide range of applications, including transportation, electricity generation, and industrial processes. It is a clean-burning fuel that produces only water when it is burned, making it an attractive option for reducing greenhouse gas emissions.

Traditionally, hydrogen has been produced using fossil fuels, such as natural gas, which has contributed to greenhouse gas emissions. Green hydrogen, on the other hand, is produced using renewable energy sources such as solar or wind power to generate the electricity needed for the production process. This can help to reduce the carbon footprint of hydrogen production and make it a more sustainable option.

Green hydrogen can be produced using a process called electrolysis, in which water is split into hydrogen and oxygen using electricity. It can also be produced through the process of reforming, in which natural gas is converted into hydrogen and carbon dioxide. However, the latter process is not considered to be a truly "green" method of hydrogen production, as it still involves the use of fossil fuels.
