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 in Qatar from natural gas (79%), whilst the balance is supplied by oil. In 2009, Qatar produced of natural gas, three times the amount produced in 2000. Although the increase in natural-gas production fuels the growing natural-gas requirements of domestic industry and its GTL projects, the bulk of this increase is going towards LNG exports. Qatar's natural-gas consumption in 2009 was approximately . During 2009, Qatar exported over of natural gas, 70% of which was LNG. Qatar currently exports about of natural gas per day to the UAE and Oman through the Dolphin pipeline. In 2016, Qatar Petroleum has entered into an
