Abstract

This study aims to assess different priority scenarios for developing Green Hydrogen (GH2) projects in Bahia, considering different input conditions in a mathematical model. This analysis supports the decision-making process regarding implementing GH2 production units, especially those utilizing the water electrolysis technique and electricity from renewable sources. Using the Analytic Hierarchy Process (AHP) method, eight hypothetical scenarios were modeled, considering the use of on-grid and off-grid renewable energy, production intended to meet local or external demands, and water availability for the electrolysis process. Due to the abundance of water resources and renewable energy sources, the Bacia do Rio Grande region emerged as the most suitable for the implementation of GH2 projects in the majority of the analyzed scenarios. However, the Metropolitano de Salvador region is the top option when factors such as development, infrastructure, and GH2 demand (internal and external) are more significant.
