Análisis de ciclo de vida de combustibles por proceso Fischer-Tropsch para la descarbonización en Imbabura, Ecuador

Abstract

From industrial revolution has been detected an increased on carbon dioxide (CO2) in the atmosphere. An essential part is attributed to use of fossil fuels, that improved the economic development, while contributed to global warming. Some governments are promoting alternatives for the decarbonization of the energy matrix. In Ecuador, fossil fuels account for 71 % of the energy matrix, emitting greenhouse gases due to energy use. Therefore, the objective of this work is to analize mitigation of the global warming potential due to the use of synthetic alternative fuels in Imbabura. The methods addressed involve (I) Determination of objetctive and scope of the system, II) Determination of system boundaries using process diagrams for the synthesis of carbon dioxide (CO2) and green hydrogen (H2) for the production of electrofuels; (III) development of the life cycle inventory; and (III) calculation of global warming potential. The results indicate that for 1 MJ of electrofuel, 0.03041 kg of CO2-equivalents are generated, which reduces emissions from traditional fuels by 33 %. In the province of Imbabura, for the complete substitution of gasoline, has the potential to decrease global warming in 388 thousand tons of CO2 per year.
