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 deal between the U.S. and Europe opens up access to cheap American natural gas, which allow Europe to diversify its supply base, but may threaten the Renewable Energy transition. Currently, Europe's main natural gas supplier is Russia. Major pipelines pass through Ukraine and there have been several disputes on the supply and transition prices between Ukraine and Russia. In September 2013, it was reported that multiple factors have conspired to cause Europe as a whole to decrease its use of natural gas and make more use of coal. The report also contains updated price trends. In South America, the second
