CNG
CNG, a fuel based primarily on methane, is the cleanest of all fossil fuels, as when burned, it releases carbon dioxide and water vapor into the atmosphere: the same compounds we exhale when we breathe, helping to reduce the harmful effects of greenhouse gas emissions.
LPG
LPG is a mixture of gaseous hydrocarbons produced from natural gas and oil extraction and from oil refining. It is automatically generated during the production of methane and during the refining process itself. LPG has lower greenhouse gas emissions than other fossil fuels when measured on a total fuel cycle.
HYDROGEN
Hydrogen is a zero carbon gas and the most abundant element in the universe. It can be produced via a number of methods, including solar and wind power or water electrolysis. Transport and distribution can be done via pipeline, high pressure tube trailer and liquified form. Within a fuel cell, compressed hydrogen (up to 700 bar), in contact with oxygen from the air, generates electricity for the car engine and produces only water as exhaust.
LNG
LNG is a non-toxic liquid, formed when natural gas is cooled down to -160°C/-260°F. This non-flammable liquid is 600 times smaller in volume than when in its gaseous state, and therefore it is both easier and safer to handle and ship. LNG is the cleanest fossil fuel. It is an excellent alternative to reduce greenhouse gas emissions and help combat global warning. Combined with proper site equipment, LNG can be boiled off in order to produce and deliver CNG at the same station.
