The first fill up…
I recently had the opportunity to take the Tahoe for its first CNG fill up and took a few photos. A few comments about what CNG actually is…
We’re all familiar with gasoline, a liquid dispensed in gallons that flows from the station pump right into our tanks. And most know gasoline comes from oil which is refined into products we can use. So how does CNG differ?
First off, CNG is a gas, not a liquid. Most commonly, natural gas is produced from reservoirs underground but it can also be captured in the form of bio methane (more on this in a later post). You don’t have to do much to natural gas before you use it, no refining needed. Before it goes into your tank, however, it is compressed to about 1% of its original volume. Compressing just means the gas is brought under high pressure to really pack it in.
The equipment for refueling is a little different than gasoline in that the hose connects to the car with the nozzle locking in place to create a seal, meaning that during refueling there are no spills or noxious fumes like with a gasoline fill.
The pictures below are from the Clean Energy station on Washington Ave, just north of I-10 in Houston. If your from Houston you have probably passed it before. Its near Memorial Park. The day we filled up, gasoline was selling for about $2.40 a gallon, note the price photo below!
