Whereas clear automobile know-how has taken gigantic leaps ahead within the final decade, there’s nonetheless a protracted highway forward to satisfy the aggressive zero-emission targets ready on the too-near horizon.
Fleets will not be unwilling to vary, however in lots of circumstances do not need the cash, manpower, or administration to make a transfer that might disrupt their enterprise, making complementary applied sciences an vital ally for decarbonizing transportation shortly. Based on last year’s State of Sustainable Fleets, 85% of these surveyed reported that their use of unpolluted automobile applied sciences will develop throughout the subsequent 5 years. In that point, these fleets will steadiness the prices related to these rising applied sciences, in addition to approaching options in a multi-tiered method. Not all routes are the identical, particularly for long-haul fleets, and nobody utility will clear up all these points within the close to future.
For a lot of fleets, they should steadiness the great of the corporate with the great of the group.
ClearFlame Engine Applied sciences and its engine modification resolution began as a seed within the labs of Stanford College and Argonne Nationwide Laboratory. By retaining a lot of the nuts and bolts of this tried-and-true engine know-how, the group has developed a means to make use of varied liquid renewable fuels, resembling ethanol and methanol, with heavy-duty engines to considerably cut back emissions and enhance complete value of possession (TCO) — a should for any over-the-road fleet.
Diesel Tech, Supercharged
The diesel Class 8 vehicles of at the moment are a lot cleaner in comparison with their “soiled diesel” counterparts of greater than a decade in the past. OEMs have taken their efforts to a brand new degree, lowering general emissions drastically. Based on a 2021 report commissioned by the Diesel Know-how Discussion board, 2007-and-newer U.S. diesel vehicles have minimize 202 million tons of CO2, 27 million tons of nitrogen oxides, and 1.6 million tons of particulate matter from the environment.
Taking this success and constructing upon it, the ClearFlame know-how additional reduces emissions from these engines by 69-83% in contrast with diesel, relying on the area of the nation the automobiles are getting used.
“ClearFlame’s know-how has the potential to offer vital and cost-effective GHG and tailpipe emissions reductions as each EPA and CARB emissions laws name for dramatic NOx reductions by 2027,” mentioned Patrick Sofa, senior vp of technical providers at Gladstein, Neandross & Associates (GNA), whose group detailed these findings in a 2022 report. “Such options to conventional diesel gas are vital to accelerating decarbonization within the transportation trade.”
Chopping TCO and Emissions for Fleet Success
Lowered TCO is on the high of any fleet supervisor’s “will need to have” listing. To evaluate ClearFlame’s resolution versus battery-electric, gas cell, CNG, and diesel engines, GNA created a TCO model that evaluated the automobile buy value; federal excise and state gross sales taxes; upkeep, insurance coverage, and gas prices; depreciation tax advantages, incentives, and residual worth. Based mostly on gas costs from October 2021, the unique outcomes confirmed the ClearFlame retrofit choice had the bottom TCO at $1.45 per mile, averaging between $0.08 to shut to a greenback lower than different choices. When up to date with at the moment’s gas pricing, ClearFlame continued to have the bottom TCO of any choice, providing $0.29 per mile financial savings in comparison with its diesel-fueled counterpart.
The subsequent step was to create a mannequin that in contrast the potential emissions efficiency of the 5 engine choices. Whereas evaluating a zero-emission know-how resembling battery-electric and gas cell to a liquid gas like diesel or ethanol would possibly present vital variations in emission reductions, the mannequin took in a number of components. Other than tailpipe emissions, it additionally checked out wheel to effectively, tank to wheel, and effectively to tank greenhouse gasoline emissions (GHG).
Based on GNA’s analysis, ClearFlame’s know-how may considerably cut back well-to-wheels GHGs and tailpipe emissions when in comparison with diesel. Bearing in mind the impact that battery-electric charging infrastructure would have on an space’s electrical grid, and in flip a rise in emissions to offer that energy, the ClearFlame resolution supplies a near-term choice that enhances these creating applied sciences. For fleets that need to decrease emissions and cut back prices, ClearFlame’s resolution is an efficient choice that’s at the moment accessible and reduces the vary anxiousness for long-haul fleets.
