Wind and solar hydrogen for the potential production of ammonia in the state of Ceará - Brazil

The main objective of this article is to analyze the feasibility of producing ammonia as main component for the synthesis of nitrogen fertilizers in the state of Ceará - Brazil. The potential for the ammonia production, via the Haber-Bosch process with electrolytic wind and solar photovoltaic hydrogen, is described with maps showing it per unit area in each municipal division of the state. Thus, by using high resolution solar radiation digital databases and average wind regimes databases (speed, Weibull factor, terrain roughness) available for Ceará, news maps of the potentials for solar and wind hydrogen are developed. Then a map of renewable hydrogen as the sum of both was created along with the corresponding potential for ammonia production with this renewable hydrogen. Land use and environmental externalities were considered as areas where energy development would be restricted.
