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 shapes.
Methane, the main component of natural gas, has an autoignition temperature of 580 °C, [47] whereas gasoline and diesel autoignite at approximately 250 °C and 210 °C respectively. With a compressed natural gas (CNG) engine, the mixing of the fuel and the air is more effective since gases typically mix well in a short period of time.
2010: Juniper Engines Inc. (now Westport Light Duty Inc.) became a wholly owned subsidiary of Westport as a result of the acquisition of OMVL SpA in July 2010 and OMVL's 51% share of Juniper. Westport LD now offers natural gas and liquefied petroleum gas engines and fuel systems for the OEM light-duty automotive and industrial market.
EPA's greenhouse gas score [27] reflects the amount of greenhouse gases a vehicle will produce over its lifetime, based on typical consumer usage. The scoring is from 0 to 10, where 10 represents the lowest amount of greenhouse gases. The Greenhouse gas score is determined from the vehicle's estimated fuel economy and its fuel type.
In 2010, the company received a $1.8 million state grant to assist in putting biodiesel into more tanker trucks. [5] In 2014, Pearson Fuels received a $1.35 million grant from the California Energy Commission. This funding was used to convert two diesel terminals into biodiesel blending terminals, allowing for the simultaneous loading of ...
One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values : 900 BTU/cu ft (9.3 kWh/m 3 ) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline).
California’s gas prices already average $4.00 per gallon, about a dollar higher than the national average. High gas prices hit the state’s low- and middle-income households, and rural ...
The remaining 15% of California's natural gas is produced in-state, both off-shore and onshore. Natural gas-fired electricity generator plants have been the dominant use of natural gas California for many years. Natural gas is a dispatchable resource that fills in the gaps from other electrical resources when peak power loads are needed.
