The natural gas vehicle market is limited to fleet vehicles and other public use vehicles like minibuses in larger cities. However, the state-owned bus company RTP Of Mexico City has purchased 30 Hyundai Super Aero City CNG-Propelled buses to integrate with the existing fleet as well as to introduce new routes within the city.
Bi-fuel vehicles switch between gasoline and the other fuel, manually or automatically. [2][3][4][5] A related concept is the dual-fuel vehicle which must burn both fuels in combination. Diesel engines converted to use gaseous fuels fall into this class due to the different ignition system. The most common technology and alternate fuel ...
Compressed natural gas. Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical ...
According to Primus Green Energy, the STG+ process converts natural gas into 90+-octane gasoline at approximately 5 US gallons per million British thermal units (65 litres per megawatt-hour). [4] The energy content of gasoline is 120,000 to 125,000 British thermal units per US gallon (9.3 to 9.7 kilowatt-hours per litre), making this process ...
[10] Vehicles that have already been certified can qualify for the tac credit by meeting these additional requirements. The vehicle must be new, and the original use for the vehicle by the taxpayer receiving the credit should not change. The tax credit will only be given to the original purchaser of the vehicle, and not to a secondhand owner.
A Shell Autogas refuelling station. Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane. Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared ...
Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems. SNG in the form of LNG or CNG can be used in road, rail, air and marine transport ...
The synthetic fuel is extremely clear because of the near-total absence of sulfur and aromatics. Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of ...
