Hard Working Trucks recently caught up with ampCNG CEO Grant Zimmerman who took on various topics, including Cummins Westport’s new ISL G Near Zero natural gas engines, California’s treatment of the natural gas vehicle industry, natural gas vehicle performance and the future of natural gas truck applications.
Besides owning and operating 19 compressed natural gas (CNG) stations across the U.S., Chicago-based ampCNG assists in designing CNG pilot projects to help fleets transition to the cleaner-burning fuel.
For even lower emissions performance, ampCNG also offers fleets renewable natural gas (RNG) which it produces in Indiana from organic waste at its farm-based anaerobic digestion facility, the largest of its kind in the U.S.
HWT: How much of an interest are customers taking in RNG vs. CNG?
Zimmerman: RNG is of huge interest to all of our customers. There’s not enough RNG to supply the demand; however, we and others in the industry are working hard to change that and bring on more supply. CNG is of interest primarily in selected markets where diesel prices remain above $2.50 such as California, Oregon, Washington, and several east coast states.
HWT: What are the cost differences between RNG and CNG? What accounts for that difference?
