The Green Fuel

In a context of increased public awareness of the importance of environmentally responsible energy use, there is a tendency for all energy sectors to position themselves as “GREEN”. Indeed, the term is so frequently invoked that its meaning is often obscured.

CO2 affects the climate negatively by depleting the ozone layer and increasing global warming. Moreover, Increased concentrations of carbon dioxide (CO2) lowers the content of zinc and other nutrients in important food crops. Zinc deficiency is currently responsible for large burdens of disease globally, and the populations at highest risk also receive most of their dietary zinc from crops.

Autogas’ status as an eco-friendly fuel is based not on rhetoric but rather on a solid platform of tangible and scientifically-proven advantages. LPG has three physical properties that are particularly relevant to its carbon footprint:

>>In comparison to most hydrocarbons, LPG has a low carbon to hydrogen ratio, which means that it will generate lower amounts of CO2 per amount of heat produced.

>>It has a comparably high heating value, meaning it contains more energy per kilogram than most competing fuels.

>>According to the United Nations, International Panel on Climate Change (IPCC), LPG is not a greenhouse gas, meaning it is assigned a global warming potential (GWP) factor of zero. The IPCC lists the GWP factor of CO2 as 1 (by definition as it is the equivalent measure of a carbon footprint) and methane as 25.

An Overview Result of the Auto-Oil II Program

The report highlights not less than 16 specific advantages of Autogas, including:

>>Relatively high octane number providing room for increase in the compression ratio and fuel efficiency of dedicated engines;

>>Lower particulate emissions and lower noise levels relative to diesel and petrol, making it more attractive in urban areas;

>>Its low emissions have low greenhouse gas effect and low NOx precursors;

>>It contains negligible toxic components;

>>It has no sulphur levels giving rise to no sulphur dioxide emissions;

>>Autogas offers a series of comparative advantages as regarded non-regulated pollutants:

 PAH (polycyclic aromatic hydrocarbons) and aldehyde (formaldehyde, acetaldehyde, acrolein) emissions are much lower than diesel-fuelled vehicles;

 Benzene, Toluene, Xylene (BTX) emissions are absent in autogas vehicles;

 Summer smog formation potential is lower than that of petrol.

Recognizing these advantages, the European Parliament has called on the Commission to consider the role and potential of gaseous alternative fuels, such as Liquefied Petroleum Gas (LPG) and natural gas, which can contribute to the immediate reduction of CO2 emissions and diversification of the energy supply. LPG Autogas out-performs petrol and diesel, and most alternative fuels in majority of studies, comparing the environmental performance of conventional and alternative fuels that have been conducted around the world in recent years.
