Propane, which is generally known as liquefied petroleum gas (LPG or LP-gas), or AutoGas in Europe, is a three-carbon alkane gas (C3H8). Propane has one of the highest energy densities of all alternative fuels, so propane vehicles can go farther on a tank of fuel. This is one of the reasons that it is used by many fleets, … Continue reading
In 2003, President George Bush, in his State of the Union address, announced a $1.2 billion hydrogen fuel initiative with the express intention to reduce America's dependence on foreign oil and to provide the fuel we need to reduce gasoline consumption in our vehicles. That financial commitment enabled scientists to … Continue reading
