The biomethane, which consists of the same molecule as natural gas, namely CH 4 or methane, is then injected into the gas grid. The natural gas is subsequently extracted from the grid and compressed by means of a CNG installation to be used as transport fuel. Biomethane can be blended or used up to 100% depending on availability and customer Flex fuel is a system that can use similar fuels in the same system such as pure gasoline to 85% ethanol. Dual fuel will use two different fuels that will feed two systems. Sounds expensive, but LP gas is not the same as natural gas — the only similarities are that they’re crude oil products and highly combustible. They differ in their: Energy content: LP gas has a heat content of 93.2 megajoules per cubic meter (MJ/m 3), and natural gas has a heat content of 38.7 MJ/m 3. Density: LP gas is heavier than air, and natural gas is Natural Gas is also made up of a mixture of different hydrocarbons, such as gasses like ethane, propane, butane, and pentane. However, the greatest benefit of natural gas is that its main component (roughly 80%) is the relatively simple hydrocarbon methane. This simple structure makes natural gas much easier to refine for commercial use. Many heavy-duty natural gas vehicles use spark-ignited natural gas systems, but some systems use a diesel-like compression injection. In a spark-ignited system, the engine functions the same way as a gasoline engine. Natural gas is stored in multiple fuel tanks, or cylinders, typically behind the cab of the vehicle. Both have auto-ignition temperatures over 1,000°F, much higher than the auto-ignition temperature of gasoline vapor, as shown in Figure 2. Figure 2. Auto Ignition Temperature. Hydrogen's flammability range (between 4% and 75% in air) is very wide compared to other fuels, as shown in Figure 3. Under the optimal combustion condition (a 29% Over the past few years, however, CNG has widely become an alternative clean fuel to conventional fuels. According to worldwide natural gas vehicles (NGV) statistics, NGVs have reached more than 28,540,819 in 2019 and natural gas fueling stations have reached 33,383 in the same period. The Asia-Pacific region dominates the game with a sweeping There are benefits and drawbacks to both storage solutions, particularly when discussing mobile equipment. CNG is stored as a gas at 2,900 to 3,600 psi, while LNG is stored as a liquid at a very kTF6.
