Though some OEMs have signaled that the end of the ICE age is nigh, reports of the combustion engine’s death as the backbone of the commercial-trucking industry are greatly exaggerated. Battery-electric vehicles are seeing continued growth in various medium-duty and last-mile delivery sectors, but their lack of energy density and cost per have prevented them from gaining market share for Class 6 and larger commercial vehicles in North America.

Several suppliers are anticipating that this trend will persist over the coming decades and are making major investments in the development of alternative fuel systems for diesel combustion engines. One such supplier is Hexagon Agility. Based in the northern suburbs of Charlotte, North Carolina, Hexagon recently announced expansion plans of its Salisbury, North Carolina facility to field orders and installations of its compressed natural gas (CNG) fuel systems.
