Proposta de implementação do hidrogênio verde para abastecimento da frota de ônibus na cidade de Sobral

Abstract

Fossil fuels were of great help to the development of the society in which we live, but with their use they brought an increase in the concentration of greenhouse gases in the atmosphere, causing an acceleration in the increase in global temperatures and strongly impacting the greenhouse effect. To minimize this damage, society proposes an energy transition in order to emit fewer greenhouse gases. This work proposes the application of Hydrogen supported by Renewable Energy to reduce greenhouse gas emissions in the transport sector of the city of Sobral, in Brazil, by replacing diesel-powered public buses with fuel cell buses powered by hydrogen. To serve the new bus fleet, it is necessary to produce 457.38 kg per day of hydrogen gas, which goes through several processes until it is supplied by the buses. The entire production, storage and supply system requires a total of 27,754 kWh of energy per day, so a Solar Park was designed to meet this demand. Finally, an economic analysis was carried out which showed a negative Payback at the end of 20 years, mainly due to the high cost of buses powered by hydrogen fuel cells, but these are technologies that tend to reduce their price over the years and the change pays off. as the amount of harmful components that are released into the atmosphere annually is very large and amounts to tons.
