Local gas company trials diesel dual-fuel kits on long-haul trucks

As fleet operators increasingly aim to enhance fuel efficiency and reduce costs, natural gas company Tetra4, a subsidiary of JSE-listed energy company Renergen, has started trialling diesel dual-fuel (DDF) kits on two European brands of trucks to establish the advantages of natural gas as a fuel source. Preliminary results of the trial show that at least 50% of diesel can be substituted with gas, says Renergen CEO Stefano Marani, who tells Engineering News that depending on further initial results, the company aims to introduce the trucks with the DDF units to run in fleet operations for a similar or shorter timeframe.
