Compressed natural gas Compressed natural gas Compressed natural gas (CNG) (methane stored at high pressure) is a fuel which can be used in place of gasoline, diesel fuel and propane/LPG. CNG combustion produces fewer undesirable gases than the fuels mentioned above. It is safer than other fuels in the event of a spill, because natural gas is lighter than air and disperses quickly when released. Biomethane – cleaned-up biogas from anaerobic digestion or landfills – can be used. CNG is made by compressing natural gas, (which is mainly composed of methane, CH), to less than 1 percent of the volume it occupies at
Natural gas prices above shale deposits compared to the rest of the US, highlighting that natural gas markets have become less integrated due to pipeline capacity constraints. Prices of natural gas for end-consumers vary greatly throughout Europe. One of the main objectives of the projected single EU energy market is a common pricing structure for gas products. A recent study suggests that the expansion of shale gas production in the U.S. has caused prices to drop relative to other countries, especially Europe and Asia, leaving natural gas in the U.S. cheaper by a factor of three. It is expected that the TTIP trade
