Oklahoma Firm Operates 44 CNG-Fueled Peterbilts,
Shifted to Momentum for Its Ten Most Recent Trucks

Clean Energy Fuels is talking up Oklahoma’s Schwarz Ready Mix as a family-owned company that’s taking advantage of compressed natural gas to lower its operating costs while doing its part for cleaner air.

Schwarz began using CNG trucks when the 11.9-liter ISX12 G engine by Cummins Westport became available. The firm began with 16 Peterbilt trucks, Clean Energy says, and then added another 16.

Schwarz now operates 32 Peterbilt 365 mixers and 12 Peterbilt 365 tractors. The tractors have 145-diesel-gallon-equivalent back-of-cab CNG fuel cylinders assemblies by dHybrid (now Worthington), says company president Philip Schwarz.

Side-Mount for the Mixers

The mixers have 80-DGE fuel systems, consisting of two side-mounted unit on each truck. The ten most recent trucks have twin rail-mounted units by Momentum Fuel Technologies, Schwarz told F&F. Momentum is a unit of Rush Enterprises, a major Peterbilt dealer.

Schwarz has invested in private filling stations at two separate facilities, Clean Energy says. One is a compact, self-contained CNG-in-a-Box unit by GE installed and supported by Clean Energy.

Schwarz Ready Mix supplements its in-house time-fill CNG fueling with public-access infrastructure.

‘Oklahoma City Is Blessed’

“Oklahoma City is blessed with lots of places to fuel,” Schwarz says.

The Schwarz fleet currently uses from 550,000 to 650,000 gallons of fuel per year, Clean Energy says. “By switching to CNG, their emission improvement with the low-end estimate includes a reduction in greenhouse gases of approximately 1,640 metric tons every single year,” Clean Energy says, “the environmental equivalent to annually planting over 41,992 trees, removing over 340 cars from the road or recycling 580 tons of waste that would have been landfilled.”

Using CNG has also helped Schwarz secure work on LEED (Leadership in Energy & Environmental Design) certified construction projects, the fuel provider says.
