Resumen
O biometano é um combustível renovável promissor para utilização em veículos leves e de passeio. Através da reação de combustão completa em condições estequiométricas, é possível identificar o potencial de redução nas emissões de dióxido de carbono em até 15,06% ao substituir o gás natural por biometano. Cinco cenários foram avaliados, nos quais 1%, 5%, 10%, 15% e 20% da frota veicular de veículos leves e de passeio alimentados com gás natural seriam substituídos por biometano. Para 1% de substituição é possível reduzir 9.230 tonCO2/ano. Para 20% de substituição seriam reduzidos 184.593 tonCO2/ano. A produção atual de biometano nos países avaliados aponta que no Chile seria possível a substituição de 15%, reduzindo em 390,93 tonCO2/ano, enquanto o Brasil, com 20% de substituição, reduziria as emissões em 13.244 tonCO2/ano.
Biomethane is a promising renewable fuel for use in light and passenger vehicles. Through complete combustion reaction under stoichiometric conditions, it is possible to identify a potential reduction in carbon dioxide emissions by up to 15.06% when replacing natural gas with biomethane. Five scenarios were evaluated, in which 1%, 5%, 10%, 15%, and 20% of the light and passenger vehicle fleet powered by natural gas would be replaced by biomethane. For a 1% substitution, it is possible to reduce emissions by 9,230 tonCO2/year. For a 20% substitution, emissions would be reduced by 184,593 tonCO2/year. The current biomethane production in the evaluated countries indicates that in Chile, a 15% substitution would reduce emissions by 390.93 tonCO2/year, while in Brazil, a 20% substitution would reduce emissions by 13,244 tonCO2/year.
