Abstract
This chapter comprehensively explores Hydrogen Production Technologies, recognizing them as a set of key techniques that play a crucial role in the generation of the fundamental energy vector for the future of the energy sector. The growing importance of these technologies is evident, especially in the face of the imperative need to meet the climate goals set out in the Paris Agreement. In this context, the study presents a detailed classification of Hydrogen Production Methods, taking into account three fundamental parameters: the Primary Energy Source used, the Physical/Chemical Process employed and the Substrate consumed in the process. This approach revealed the existence of eleven distinct production methods, all of which were grouped and identified through a "Hydrogen Rainbow". In each of the colors of this rainbow, we explore the main aspects of relevance, deepening knowledge in this area.
