In quest for a sustainable motorisation: the CNG opportunity

Abstract

This article describes the opportunity deriving from the substitution of conventional fuels with the compressed natural gas (CNG). The advantages of this fuel are: a relevant, as it concerns consumer's expenses and ecological aspect b rapidly achievable c close to hand for Europe, the USA and other countries where the motorisation is at the take-off stage, like the BRIC countries and Iran, Pakistan, Indonesia and so on.These advantages makes CNG a viable solution, with relevant advantages both on the side of pollution and expenses, while waiting for the availability of new technologies. Presently, the most important bottleneck for a large-scale implementation of this solution is represented by a possible shortage in the distribution network. Those countries crossed by gas pipeline could rapidly overcome this bottleneck without relevant costs. Otherwise, the solution could be achieved either through gas carrier's ships or through local production of biomethane by the exploitation of biomasses.

Implementation of CNG as an Alternative Fuel for Automobiles in Nigeria: Benefits and Recommendations

“…However, currently, Nigeria depends mainly on gasoline and diesel as fuel for automobiles [21]. Any little increase in CO2 emission from human activities has a destabilizing effect globally, as an increase in CO2 emission leads to an increase in temperature which results in increased emission from natural sources leading to increased occurrence of natural disasters [23]. There is a steady rise in CO2 emissions in Nigeria due to the transport sector (Fig.…”

“…CNG has a high octane number, making it less likely to need antiknock additives, such as benzene and lead [44]. Also, this feature means CNG has a higher heat of combustion and lower emission [23]. This makes CNG engines superior in performance than gasoline and diesel engines.…”

“…These highly populated cities are also likely the most polluted too. Therefore, the use of CNG automobiles in highly populated cities would abate both emission and noise pollution [23]. This strategy was very effective in India.…”

The Second Automotive Revolution Is Under Way: Scenarios in Confrontation

“…The second group covers countries that have chosen agrofuels, such as Brazil and Sweden (Amatucci and Spers, 2010). The third group is composed of the countries preferring natural gas, such as Italy, Pakistan, Russia, Poland and Iran (Stocchetti and Volpato, 2010). In the fourth group, we find the countries that have chosen electricity, promoting plug-in hybrids and electric vehicles.…”

Implementação de corredores azuis na Região Sul do Brasil: uma avaliação baseada no fluxo e na autonomia dos veículos pesados de carga

“…As principais vantagens da substituição do óleo diesel pelo gás natural para a realização do transporte de cargas são: menores emissões de poluentes e gases de efeito estufa após a combustão no motor, redução da demanda por petróleo aproveitando a ampla disponibilidade do gás natural no mundo, competitividade do gás natural como combustível e desenvolvimento tecnológico já existente de veículos movidos a gás natural (GALBIERI et al, 2018;ROSE et al, 2013;SEMIN, 2008;STOCCHETTI;VOLPATO, 2010 Os principais critérios levados em consideração pelo estudo para a seleção da rota latinoamericana foram: (i) a disponibilidade de acesso à rede de gás natural da área, (ii) a importância da rota para a integração entre os centros econômicos e industriais da região e (iii) a alta intensidade de tráfego de veículos. Os autores estimaram a necessidade de instalação de 34 postos de abastecimento ao longo da rota para que a mesma pudesse atender os veículos a gás Figura 7 -Corredores azuis para o estado de São Paulo, considerando os cenários 1 (linha cheia, limitado às regiões com presença de gasodutos) e 2 (linha pontilhada, para todo o estado, independente da presença de gasodutos).…”
