COMMENT ON DE BOOK:
Hydrogen in not found free in nature. We have the example in water whose molecules results from the union of two hydrogen atoms with one oxygen. Returning to the case of water, if we want to separate its components, it can be done by electrolysis. But the basic question is that the electrolysis process requires energy, which is obtained through electricity generated in thermal, nuclear, etc. Another example, methane (CH4), can be used to make hydrogen, but it is a polluting fossil source. And this is where the concept of GREEN HYDROGEN comes in: it is that which is obtained through renewable energies (wind, solar, etc.), with zero polluting emissions. This work is of great interest to engineering companies, energy companies, construction companies, installers, designers, electrical companies, energy agencies, state companies, official bodies, etc. It is also very suitable for training courses.
