FuelMule from Ultimate CNG is a mobile, self-contained CNG station providing
onsite fast-fill fuel delivery.
Mobile Onsite Fueling
Though not yet a common practice, some fleets are exploring mobile
onsite CNG fueling options, also known as ―wet hosing.‖ In this scenario, all
vehicles return to the yard in the evening, and a CNG supplier fuels the
vehicles overnight. A fleet may choose this option instead of building onsite
infrastructure. Mobile onsite fueling can also be used as a temporary
arrangement when CNG vehicles arrive before infrastructure is operational or
when infrastructure is out of service. This option may not be available in all
geographic areas. A fleet should consult local code authorities to identify any
restrictions to mobile fueling.
Renewable Natural Gas
Renewable natural gas (RNG), produced at locations such as landfills or
dairy farms, can supply gas to onsite fueling infrastructure for vehicles such as
refuse haulers and dairy trucks. There are equipment costs associated with
refining RNG into pipeline-quality gas. Once the RNG has been refined,
equipment and installation costs for a fueling station using RNG are similar to
