Near Zero: Natural gas can help fleets meet decarbonization objectives


Because the trucking trade embarks on its transition to zero emissions, there are available and straightforward to implement applied sciences that may get it near that concentrate on.

Take for instance, pure gasoline. A fleet powered with renewable pure gasoline may even be carbon unfavourable in the present day, for the reason that gas is created from methane that will in any other case be launched into the ambiance.

C.A.T. is already working 12-liter pure gasoline engines, however a 15-liter model will open extra lanes. (File picture)

“The gas is cheaper. It provides fleets the power to scale back their emissions with none will increase prices – possibly with some financial savings and possibly with a chance to generate some [carbon] credit,” mentioned Bruce Winchester, govt director of the Canadian Pure Fuel Automobile Alliance. He was talking at a Greentech panel at Truck World April 19. “Not one of the different applied sciences actually supply that.”

Pure gasoline is getting renewed curiosity after Cummins introduced plans to carry to market a 15-liter pure gasoline engine, extra able to assembly the Canadian trade’s energy calls for than the present 12-liter.

15-liter CNG engine

“The 12-liter product Cummins had within the market didn’t fairly meet muster,” Winchester mentioned. “The X15N is considerably higher. It’s very, similar to diesel efficiency and we’re beginning to hear how nice the engine really is.”

One of many first Canadian fleets to get its palms on the brand new 15-liter pure gasoline engines is C.A.T. It already had deployed about 100 vans with the 12-liter engine.

“The 15-liter has been performing nice,” mentioned Jonathan Royal, senior director of asset administration for C.A.T. “So removed from what we’ve seen, the horsepower and torque is corresponding to diesel.”

Along with offering extra energy, the gas financial system is the same as its smaller sibling, Royal mentioned, and oil intervals have been practically doubled. C.A.T. runs its pure gasoline vans between Quebec Metropolis and Laredo, Texas. It labored with a gasoline provider to make sure a fueling community was in place alongside that route.

Fueling easy

The largest problem associated to the tools is staying on prime of upkeep schedules. “You’ve obtained to watch out with it,” he mentioned, noting pure gasoline engines are much less forgiving when scheduled upkeep is missed. “In case you do, these vans carry out nice.”

Fueling the vans is straightforward, and, provides Royal, “The largest constructive is whenever you get to the station there’s usually no line. You may refuel straight away. It doesn’t odor. You don’t get leaks in your boots and gloves. You simply take the nozzle and hook it to the tank.”

Kyle Cooper, enterprise improvement – low carbon transportation options with Enbridge, can be seeing elevated curiosity in pure gasoline as a trucking gas. He mentioned the launch of the 15-liter Cummins is “an enormous sign to the trade that we’re right here to remain, we’ve invested on this expertise, and we see pure gasoline as a future answer for decarbonizing the trade.”

When fueled by renewable pure gasoline, vans really act as “carbon sinks” mentioned Winchester. Nonetheless, he acknowledged there are some tailpipe emissions, even when the general carbon output is unfavourable. Changing to pure gasoline permits fleets to generate carbon credit which might then be bought.

Royal, nonetheless, acknowledged thar RNG is priced at a premium. “In in the present day’s world, RNG is kind of costly. However RNG makes whole sense a minimum of for the subsequent decade.”

The extra prices of RNG comes from the method required to wash it to the wanted purity. It’s then blended with typical pure gasoline within the pipeline, nonetheless, Cooper mentioned. At a molecular stage, RNG performs precisely the identical as typical pure gasoline.

Store retrofits

Requested what fleets have to learn about changing to pure gasoline, Royal mentioned “It’s a challenge in itself. It’s a must to take into consideration not solely shopping for the truck and spec’ing the truck correctly, however spec’ing the correct tanks. The place are your lanes? Is there good help on the highway? Is there an satisfactory fueling community to service your lanes? It’s a must to prepare your technicians, prepare your drivers. You actually should map out and calculate the ROI on it…all variables have to be mapped out earlier than launching your self into that new journey.”

Present retailers could should be retrofit, their air flow techniques tailored. Fuel-fired heating is a no-go and even {the electrical} conduit could have to be tailored. This may be cheap on a brand new construct, however expensive when retrofitting an current store.

“In case you do issues proper, it’s a expertise that’s working and has been confirmed,” Royal mentioned. “CNG and RNG is the one different power obtainable available on the market that we are able to apply now.”
