Modern natural-gas-fueled engines have a high energy conversion efficiency. As a result, gas-engine-based cogeneration installations can have a CO{sub}2 emission per kWh that is a factor 5 lower than that for c
Figure 1 compares the ranges of country-specific average estimates of normalized (per kWh) GHG emissions from fossil fuel chains according to the ecoinvent database and the ranges according to the systematic literature review by NREL. (The figures provided by NREL (JoIE, 2012) correspond to harmo...
Liquefied Natural Gas (LNG) is a type of alternative fuel that ranks second in sales to LPG in the United States. It is estimated that in 2001, about 105 million gallons of gasoline equivalent of LNG were sold for transportation purposes. ...
Power factor: 0.8 Operating voltage V.: 400 Electrical efficiency %: 40.2 Fuel consumption at 100% load, 257.70 nm3/h Fuel consumption at 80% load, 206.16 nm3/h Oil consumption per carbon monoxide, 0.3 g/kWh Fuel Types CNG, LNG, PNG, Oilfield Associated Gas, Coalmine Gas, Coalbed Gas...
In the present study, the differences in emission between the liquid fuels were tested using a heavy-duty diesel engine that was attached to an engine dynamometer and the emission samples from compressed natural gas were collected from a bus that was driven on a chassis dynamometer. Thus, the ...
With large emission of the single cylinder of 300 Serise gas genset, low pressure gas and air can be inhaled natu rally by the prime mover( the pressure of the gas source only needs to be greater than 2kpa ), which makes the gas genset has wider application sco...
the feasibility of the different natural gas pathways used in motor vehicles were assessed to determine the advantages and disadvantages of each option. To demonstrate how differently each factor can weigh in, case studies were conducted in six different countries spanning three continents. (AMF Task...
Natural gas is the main energy source and carbon emission source of integrated energy systems (IES). In existing studies, the price of natural gas is generally fixed, and the impact of price fluctuation which may be brought by future liberalization of the terminal side of the natural gas marke...
The relevant emission factors are also shown in Table 5. It can be seen that Iran Offshore Oil Company had the highest emission factor (33.29 cubic meters of gas per barrel of oil) whereas the Arvandan Oil and Gas Company had the lowest (2.97 cubic meters of gas per barrel of oil) (...
GHG emissions of electricity production from PV technologies are assumed to be 31 g CO2-eq./kWh being between GHG emission for mono-silicon and cadmium telluride systems [66]. 5.2. Methane supply Natural gas is considered to be the methane source used for hydrogen production. Average cost for...
