Avaliação de rota de produção de eletrocombustíveis para aviação utilizando eletricidade solar fotovoltaica e captura de dióxido de carbono diretamente do ar

Abstract

This work evaluated a production route for electrofuels, which store renewable and potentially carbon neutral electricity in their chemical structure. The evaluated route produces hydrogen by providing solar photovoltaic electricity to the electrolysis process. Direct air capture (DAC) technology relying on absorption provides carbon dioxide. Both gases take part in a synthesis process, in which the main unit is the Fischer-Tropsch synthesis. Aviation kerosene was chosen as the final product to be obtained. Among the reasons that led to the choice of studying this route, it is important to highlight the recent interest in the use of photovoltaic and DAC technologies for fuel production. The main results showed a limited production potential as well as high costs if compared to conventional aviation fuel, which might lead to the need of incentive policies. As a conclusion, it can be stated that the studied route is a niche opportunity to produce electrofuels. Thus, this work contrasts with current optimistic expectations for this type of electrofuels production route by academic literature and companies.
