Análise de viabilidade técnica e financeira de uma planta de produção de amônia verde no estado do Ceará

Abstract

The energy transition has been one of the main topics discussed in the electrical sector. In this view, green hydrogen is deemed as primary input to support the reduction of carbon dioxide emissions into the atmosphere. Brazil could be one of the most important players on the hydrogen international market due to its renewable energy generation. The state of Ceará stands out as a result of its strategic location and natural resources being suitable for renewable energy generation and transportation worldwide. This study shows an economic evaluation of a photovoltaic power plant (500 MW) located in the city of Umari (CE). Also, it details the sizing of a green ammonia production plant (123,2 MW of electrolyzers) and its financial assessment of feasibility. The energy will be purchased via a Power Purchase Agreement (PPA). Once the location for the photovoltaic power plant is defined, it is conducted a simulation via PVsyst in order to evaluate the amount of energy to be sold to the hydrogen plant. In this way, the energy produced is the constraining factor in resource production (H2). Therefore, the energy consumption of each process in the proposed plant (electrolysis, Haber-Bosch, water treatment, air separation unit) will be determined.
