Upfit Initially for Cummins ISX Trucks Allows CNG or LNG

Chesapeake Energy’s Peake Fuel Solutions unit has launched DNG – for diesel natural gas – as a “transformative” new dual fuel system for heavy duty trucks, starting with the 15-liter Cummins ISX.

It’s another arrow in the quiver as natural gas-producing Chesapeake seeks to boost the transportation market. Chesapeake-Peake has partnered with GE for a self-contained CNG fueling unit called CNG In A Box, and is backing 3M’s bid to produce a new line of economical compressed natural gas fuel systems.

Peake showed this Kenworth T800 with CNG-fueled DNG upfit at last month’s ATA 2012 Management Conference & Exhibition in Las Vegas.

And DNG? “It will save you a truckload of money,” Peake says. DNG is based on “Peake Fuel Solutions technology developed with both internally and externally sourced resources,” says Chesapeake natural gas ventures VP Kent Wilkinson.

300-Plus Orders

The company has secured U.S. EPA IUL-Inside Useful Life certification of the product, he says, allowing it to target both new trucks and, more importantly, relatively new trucks already in service for retrofit.

“We are currently evaluating the market to determine if we proceed with final CARB [California Air Resources Board] certification,” Wilkinson says.

Peake notes that trucks may be outfitted for either CNG or liquefied natural gas fuel, and that the DNG-converted engines can fall back on pure diesel if necessary.

E&P Too

The company has back orders for more than 300 systems, Wilkinson told F&F. Chesapeake’s Oilfield Trucking Solutions affiliate (the former Hawg Hawling), which hauls water to and from frack sites, is the initial fleet customer.

Chesapeake Energy’s Oilfield Trucking Solutions and Nomac Drilling affiliates are among the initial customers for the new DNG dual fuel system from Peake Fuel Solutions.

“We are working on a dealer program for companies wishing to distribute DNG,” Wilkinson says.

Peake also reports an EPA exemption allowing DNG kits to be used on Caterpillar 3512B engines on energy exploration and production drilling rigs.

“These DNG conversions can pay for themselves in just one year if diesel is mixed with natural gas from a gathering system,” the company says.

Chesapeake says it plans to convert some of its Nomac Drilling rigs to DNG.
