The enduring US automaker Tesla has made a behavior of grabbing the electrical car highlight and focusing it on automobiles, pickup vans, and long-haul semis. Nonetheless, decarbonizing the trailer a part of a tractor-trailer truck may be simply as consequential, if not fairly as attention-getting. With that in thoughts, let’s check out the main US meals distribution agency Efficiency Meals Group, which is transitioning its diesel fleet to electrical vans outfitted with solar-enabled electrical refrigeration trailers.

Reefer Insanity: Decarbonizing The US Refrigerated Truck Fleet

Within the meals distribution enterprise, electrical vans solely resolve one a part of the diesel gas downside. If the meals being hauled requires temperature controls, that usually entails an onboard diesel generator devoted to producing the electrical energy wanted to run refrigeration programs.

A generally cited estimate is about 500,000 reefers — refrigerated trailers — on the roads within the US. Add in smaller refrigerated vans and that provides as much as a whole lot of diesel gas for that generator.

Our associates over at Freight Waves ran the numbers in January of 2023 and famous that reefer gas is equivalent to straightforward diesel, besides it’s dyed crimson to differentiate it from engine gas. Reefer gas shouldn’t be permitted to be used in powering the truck engine itself, just for refrigeration generator. It doesn’t fall beneath the identical taxes scheme as normal diesel, so it’s not as costly as common diesel. Nonetheless, it’s not low cost. “As of December 2022, the national average cost was $2.74 per mile,” noticed Freight Waves reporter Alex Dryjowicz.

Placing it one other approach, Dryjowice explains that reefer gas tanks usually have a 50-gallon capability and want refilling each 2–4 days, based mostly on a mean utilization fee of 0.75 gallons of gas per hour. That may range from 0.50 to 1.00 gallons per hour, relying on the effectivity of the system.

“If a reefer unit runs out of fuel, the refrigeration generators will shut down, and the temperature-sensitive goods inside will spoil,” Dryjowice cautioned.  “It can also be difficult to restart a reefer unit after running out of fuel, so it’s best to maintain at least a quarter tank of reefer fuel at all times.”

Efficiency Meals Group Banks On Electrical Vehicles

When you caught that factor about operating out of gas, that explains why refrigerated meals haulers must tread cautiously on electrical vans. Operating out of juice can spoil a complete cargo.

Nonetheless, Performance Food Group is keen to make a go of it, with a funding help from public businesses and help from dependable personal sector companions.

PFG tapped its sprawling distribution heart in Gilroy, California, to start out issues off. In an embargoed press launch shared with CleanTechnicaPFG listed six new Class 8 Volvo VNR electrical vans as one a part of the decarbonization venture, bought with vouchers from California’s Hybrid and Zero-Emission Truck and Bus Voucher Incentive Undertaking.

Photo voltaic Panels For Electrical Vehicles

The opposite half is the alternative of diesel-powered reefers, or TRUs (transport refrigeration items) as they’re formally recognized, with 100% electrical TRUs from the agency Advance Vitality Machines. The complete “SolarTechTRU” package consists of a rooftop solar panel array of 35 kilowatt-hours per day together with a lithium-ion battery pack. The corporate notes that its patented regenerative braking system additionally produces 12 kilowatt-hours per day on common.

AEM calculates that the solar-enabled system is ample to scale back if not remove grid-sourced electrical energy to run its high-efficiency refrigeration system — although, that will depend on the temperature. The photo voltaic panels alone present 100% of every day energy for 34 levels Fahrenheit and above, and about 35% for sub-zero temperatures.

In an fascinating twist, AEM additionally notes that its expertise is engineered to be eliminated and put in on one other new trailer, or put in as a retrofit on current diesel-powered trailers. “The SolarTechTRU outlives the typical life span of cold chain trailers. The SolarTechTRU is designed to be installed onto new trailers, or to take the place of dirty diesel TRUs, and it can be moved from trailer to trailer,” the corporate explains.

Thus far, PFG has changed greater than 30 typical TRUs with AEM’s new zero-emission SolarTechTRU fashions. “Each of the electric TRU installations completed within PFG’s fleet of refrigerated trailers has helped PFG eliminate approximately 20 tons of CO₂ per TRU, per year,” PFG experiences.

Who’s Going To Cost All These Electrical Vehicles?

As for charging up the brand new vans, PFG turned to FreeWire Technologiesa well-recognized face on the pages of CleanTechnica. The title FreeWire refers back to the firm’s battery-integrated EV charging stationswhich allow it to supply ultra-fast charging with out relying instantly on the grid.

For the Gilroy website, FreeWire put in 15 of its Increase EV charging stations, which PFG can use to cost as much as 30 Class 8 electrical vans at a time.

“FreeWire’s energy requirements are nearly 10x lower than traditional chargers, reducing peak energy demand and grid strain while providing more efficient power,” PFG enthused.

The vitality storage angle additionally enabled PFG to scoot previous the road for hookups. “PFG was able to add 3MW of power needed for ultrafast charging to their existing facility, leapfrogging the local utility company’s three-year timeline,” the corporate defined.

Extra Photo voltaic Icing On The Inexperienced Cake: What About Meals Vehicles?

Rounding out PFG’s decarbonization plan for the Gilroy facility is a brand new 1.5 megawatt rooftop photo voltaic array and a 500kW/1100kWh vitality storage system, designed round charging wants for the corporate’s rising fleet of electrical vans.

That’s only for starters. PFG notes it plans to proceed working with its companions on the Gilroy venture to decarbonize its different 150 areas unfold out throughout the US.

All this exercise within the long-haul refrigerated meals distribution space reminds us that it will be an amazing thought to decarbonize retail meals vans, too, starting with the diesel-spewing ice cream vans that poison the lungs of youngsters ready in line for his or her ice lotions.

Among the many main world automakers, Nissan has teased the concept with its repurposed e-NV200 electric vanin partnership with the renewables-friendly ice cream and chocolate maker Mackie’s of Scotland.

Startups are additionally stepping into the act. The New Jersey ice cream purveyor Scream Vehicles just lately bought a battery-powered makeover from the energy storage firm Joule Case.
