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 ...
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). [22]
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.
In 1994 the U.S. National Institute of Standards and Technology (NIST) introduced gasoline gallon equivalent (GGE) as a metric for fuel economy for natural gas vehicles. NIST defined a gasoline gallon equivalent (GGE) as 5.660 pounds of natural gas, and gasoline liter equivalent (GLE) as 0.678 kilograms of natural gas. [18]
Gas plants could be sited within cities, and many major U.S. cities such as New York, Chicago, San Francisco had gas distribution lines for manufactured gas by the 1870s. [ 9 ] The first major U.S. city to pipe in natural gas was Pittsburgh, in 1883, sold by Penn Fuel Gas Company from a well twenty miles from the city, and transported via a ...
Based on research by CARB and UC Riverside, if all gasoline in California had been E15 in 2022, there would have been a 450-million-gallon reduction in petroleum consumption and greenhouse gas ...
California natural gas production typically is less than 2 percent of total annual U.S. production and satisfies less than one-sixth of state demand. [ 106 ] [ 107 ] California receives most of its natural gas by pipeline from production regions in the Rocky Mountains , the Southwest, and western Canada . [ 107 ]
Today a gallon of gasoline in California today costs $4.61 on average, just over 10 cents lower than the last month and more than 50 cents lower than last year, according to the latest prices from ...
