standard atmospheric pressure. Consisting
mostly of methane, CNG is odorless, colorless and tasteless. It's drawn from
domestically drilled natural gas wells or
in conjunction with crude oil production.
CNG is typically stored within fuel tanks
and onboard the vehicle in a gaseous state
at a pressure of 3,000 to 3,600 pounds per
square inch (psi).
A CNG engine pulls the gas out of the
onboard tank through a series of highly
pressurized lines until the gas reaches the
regulator. Inside the regulator, the pressure on the gas is reduced until it matches
the amount needed by the fuel injection
system of the vehicle's engine. Once
the gas has reached the right pressure,
it moves into the fuel injection system
and then into the engine. The gas is then
ignited inside the combustion chamber
which provides the energy to move the
vehicle forward.
According to the U.S. Energy Department,
there are about 150,000 natural gas vehicles (NGVs) on the road in the United States
and approximately 15.2 million worldwide.
NGVs can use either CNG or liquefied natural gas (LNG).
However, because of LNG's higher production cost and the need to store it in
cryogenic tanks, the widespread use of this
fuel in commercial applications has been
limited. CNG does not have these same limitations. In fact, a CNG powered vehicle gets
the same fuel economy as a conventional
diesel or gasoline powered engine and has
a number of supplemental benefits. Also,
CNG vehicles can be slow-filled overnight
or over a long period of time, making it an
ideal fuel source for COTA buses and other
fleet vehicles.
To accommodate the fueling needs of
its new CNG fleet, COTA began renovating
its existing operations and maintenance
facility and opened a second fueling station
this March, built in partnership with the
City of Columbus. The new facility is open
24 hours a day and serves COTA buses,
city CNG vehicles, and provides additional
quick-fill access lanes to the public.
Columbia Gas of Ohio, the largest natural
gas utility in the state, installed more than
4,500 feet of 8-inch plastic mainline pipe
and a metering service that provides gas at
an average pressure of 31 psi to bring the
CNG station online. In fact, according to

"We're happy to help COTA with its fleet transformation
and new CNG station," said Kurt Waninger, Manager of
Major Accounts for Columbia Gas of Ohio. "There are
numerous environmental and monetary advantages to
CNG powered vehicles. CNG vehicles produce fewer
emissions and reduce fuel costs. Natural gas, in general, is
non-toxic, non-corrosive, and non-carcinogenic. Columbia
Gas is proud to assist organizations in meeting their
sustainability and infrastructure goals."
Columbia Gas, the COTA CNG station uses
the equivalent gas volume of more than
4,400 residential homes.

Private and public organizations around
the state have also begun a similar process
of either converting or adding new CNG
vehicles into their fleets. In Lorain, Medina,
and Cuyahoga counties, Republic Services,
an industry leader in recycling and waste
services, recently announced the addition of 25 CNG-powered waste collection
vehicles into its fleet. In Dayton, the County
of Montgomery recently completed transitioning 14 tractor-trailers used to haul solid
waste to landfills from diesel fuel to CNG.
And in the city of Hamilton, Ohio the local
city government claims a fleet of 10 CNG
vehicles operated by the Electric, Utilities,
Meter Reading and Police Departments.
As diesel and gasoline fuel prices continue to rise, organizations using NGVs in
their fleet operations will continue to see
advantages and savings. However, lower
fuel prices may not be the only reason an
organization might choose to pursue this
alternative fuel.
CNG vehicles are comparable in performance to those of their mainstream fuel
brethren. Things like horsepower, acceleration, and cruise speed are all comparable in both CNG and traditional fuel
vehicles. Furthermore, compared with

conventional diesel and gasoline vehicles,
CNG vehicles offer a number of additional
environmental benefits.
When looking at the environmental impact of gasoline and diesel fueled
vehicles, compared with those powered
by CNG, NGVs produce significantly
lower carbon monoxide and greenhouse
gas emissions.
COTA reports that its CNG buses produce
approximately 15 to 30 percent lower greenhouse emissions. CNG exhaust emissions
are also significantly lower than gasoline
and diesel emissions. COTA's CNG powered buses can achieve a 70-to-90-percent
reduction in carbon monoxide (CO) emissions and a 75-to-95-percent reduction in
nitrogen oxides (NOx) emissions.
While there is an increasing number of
NGVs on Ohio's roadways - thanks, in part,
to diesel fleet transitions and the technology to retrofit gasoline or diesel engines -
there are certain costs associated with CNG
vehicles that may slow down this pace.
One of these costs is creating the
necessary infrastructure needed to support an increase in NGV use. Ohio has an
extensive natural gas distribution system
in place; however, CNG vehicle fueling
infrastructure is limited. This limited fueling infrastructure and initial high costs for
consumers may make the switch to CNG
less viable for some business, organizations, and consumers.
Finding ways to overcome these challenges and costs may be worth it in the
long run. While the path an organization
may take on this issue may vary, it is clear
that alternatives to gasoline and diesel fuels
exist and can be implemented into fleet
operations successfully.
