Our cutting-edge virtual pipeline (VP) trailers are redefining RNG transport, offering flexible solutions for a wide range of applications—including animal digesters, landfills, and flare gas capture. Engineered for efficiency, safety, and reliability, our lightweight, high-capacity trailers provide a seamless way to move RNG from source to destination.
With customizable options ranging from 534,290 standard cubic feet to 123 kilograms, we tailor each system to meet the specific demands of your RNG production and distribution process.
Renewable natural gas (RNG) is an upgraded form of biogas used as a substitute for natural gas. It is sourced from municipal solid waste landfills, digesters at wastewater treatment plants, livestock farms, food production facilities, and organic waste management operations.
Renewable gas has been safely used as a transportation fuel worldwide for many decades. It is lighter than air and thus much less volatile than gasoline or diesel. In the event of a leak, it wants to quickly rise from the scene rather than pooling like liquid hydrocarbon fuels. Because natural gas is stored in vehicles at high pressure, RNG tanks and systems are required to pass extensive tests and meet rigorous industry standards prior to operation. As a result, a Quantum Type 4 tank is actually more resistant to penetration than liquid fuel tanks used in production vehicles.
Pipeline natural gas traditionally comes from deep underground wells and is associated with petroleum production. RNG, on the other hand, is a purified form of biogas derived from organic waste material found in daily life, such as food waste, garden and lawn clippings, and animal and plant-based material. Raw biogas has a methane content of 45-65% depending on the source of the feedstock and must go through a series of steps to be converted into RNG. Treatment includes reducing nitrogen and oxygen content as well as removing moisture, carbon dioxide (CO2), and trace-level contaminants such as siloxanes, volatile organic compounds (VOCs), and hydrogen sulfide. Once upgraded, the gas has a methane content of 90% or higher. Typically, RNG injected into a natural gas pipeline has a methane content between 96-98%.
Similar to natural gas, renewable natural gas is odorless, so a distinctive sulfur-scented odor is added prior to distribution. This strong smell makes it easier to detect a leak. If you notice an odor, please inspect the vehicle for the source of the concern and then repair as needed. Note that the odorant becomes detectable at a concentration of approximately 1% by volume. However, the smell does not get stronger as the concentration increases. This means if you can smell it, the concentration is already at least 1%.
