CNG Now Fueling Lebanon Transit
Ride On With CNG
Lebanon Transit’s new Compressed Natural Gas (CNG) buses
have hit the road!
So what is CNG and how is it different than the other buses in LT’s fleet?
CNG or Compressed Natural Gas is a readily available alternative to gasoline that’s made by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. Consisting mostly of methane, CNG is odorless, colorless and tasteless. It’s drawn from drilled natural gas wells and is an abundant American Made energy source.
CNG is also an affordable alternative when compared to gasoline or diesel fuel. CNG can cut fuel costs by about 50% and lower vehicle maintenance costs.
In addition to being an abundant and lower cost fuel, CNG is also environmentally friendly and produces up to 29% less greenhouse gas emissions than gasoline & diesel vehicles.
Lebanon Transit will be fueling the new buses at its own CNG station. LT’s fueling station is part of PennDot’s P-3 project, which is slated to open 29 new CNG stations throughout Pennsylvania. The diagram below shows how the CNG Station at 200 Willow St in Lebanon Operates. (diagram from trilliumcng.com)
- 1. Gas Meter
Your local gas utility will supply a meter for the CNG station to measure the amount of gas you use. It is important to work closely with the utility to determine the pressures and flow rates that are available at your site, and if any service upgrades will be needed.
- 2. Gas Dryer
In the dryer, gas flows through filters and a desiccant bed to remove moisture and contaminants. Only clean, dry gas flows to the compressors.
- 3. CNG Compressors
The compressors are the workhorses of every CNG station and they must withstand the rigors of heavy-duty daily use over many years. To meet this demand, Trillium installs reliable Ariel compressors, as they have an unmatched record of service, long life, and superior factory support. Compressors are housed in sound-attenuated enclosures that minimize noise.
- 4. High Pressure Storage
From the compressors, Trillium’s advanced control system will manage the flow of gas and determine whether to send it to storage or to bypass storage sending the gas directly to the dispensers.
- 5. CNG Fuel Dispenser
Fuel can be dispensed through a Fast-Fill or Time-Fill system. Fast fill systems provide fill times that are similar to gasoline and diesel fuel dispensing, and often include fuel management and credit card payment systems. Time-fill systems refuel vehicles overnight while they are not in service.
