O gás natural veicular no município de Manaus: uma análise de disponibilidade, economia e meio ambiente

Abstract

With the increasing concern about fluctuations in fuel prices, the need to search for options offering greater economic viability becomes evident. In this context, compressed natural gas (CNG) emerges as a promising alternative, not only providing price stability but also significant economic advantages when compared to gasoline and ethanol. The conducted study also aims to assess the availability of natural gas in the Amazon region, with a focus on its supply in the municipality of Manaus. This involves examining existing distribution infrastructure and expansion possibilities to meet the growing demand for cleaner and more economical fuels. Another relevant aspect addressed is the analysis of exhaust emissions indices in a sample of vehicles powered by compressed natural gas in the city of Manaus, compared to conventional liquid fuels such as gasoline and ethanol. The reduction of atmospheric pollutant emissions represents a significant advantage of CNG, contributing to improved air quality and the mitigation of climate change. Through this research, the feasibility of CNG utilization in Manaus is sought to be demonstrated, while also providing insights for public policies promoting the transition to more sustainable and economical energy sources in the transportation sector.
