Electric truck vs HVO renewable diesel is the most common decarbonization choice facing fleet buyers who cannot wait for hydrogen. A Dongfeng TE8L electric tractor with a 400 kWh pack and 360 kW motor competes head to head with a diesel tractor running hydrotreated vegetable oil. This article compares CO2 per km, energy cost, maintenance, infrastructure, residual value and a worked fleet example, then sets out where each option fits a realistic overseas transition plan in 2026.
HVO, or hydrotreated vegetable oil, is a drop-in renewable diesel made from waste fats, oils and greases. It burns in a standard compression-ignition engine with no hardware change, cuts well-to-tank CO2 by 80 to 90 percent versus fossil diesel, and is available today across parts of Europe, the Middle East and selected African ports. It is not free of tailpipe CO2, but it removes most lifecycle emissions. For a fleet that cannot install chargers, HVO is the lowest-friction decarbonization step and can be adopted in a single fuel contract without any vehicle change.
The catch is price and supply. HVO typically costs 1.2 to 2.0 times fossil diesel, and in many export markets it is scarce or blended to low percentages. A truck running HVO still pays the diesel engine's maintenance, noise and local air quality costs. It is a transition fuel, not a destination, and buyers should plan a path off it rather than assume it will stay cheap as demand rises.
A TE8L on a regional haul uses about 1.1 to 1.4 kWh per km, so a 40-tonne gross combination at 1.3 kWh per km with a grid mix of 0.4 to 0.6 kg CO2 per kWh yields 0.5 to 0.8 kg CO2 per km at the tailpipe-plus-grid. A comparable diesel tractor burns 0.30 to 0.38 L per km and emits about 0.8 to 1.0 kg CO2 per km from fuel alone, before the higher well-to-tank figure of HVO improves its standing. On a clean grid the EV truck wins clearly; on a coal-heavy grid the gap narrows but the EV still leads once HVO's own production energy is counted in the full lifecycle.
| Metric | TE8L electric tractor | Diesel on HVO |
|---|---|---|
| Energy use | 1.1 to 1.4 kWh per km | 0.30 to 0.38 L per km |
| Energy cost at typical rates | $0.05 to $0.18 per kWh | $0.9 to $1.4 per L equivalent |
| Cost per 100 km | $5.50 to $25.20 | $27 to $53.20 |
| Tailpipe CO2 | 0 (at wheels) | About 0.8 to 1.0 kg per km |
| Brake and maintenance | Lower, regen cuts wear | Standard diesel service |
The cost-per-100-km row is the headline for most fleets. Even at the high electricity rate of $0.18 per kWh, the TE8L stays well below HVO diesel on energy alone, and at $0.05 per kWh the gap is more than fourfold, which is why per-kWh electricity price dominates the EV business case.
Beyond energy, the EV truck saves on maintenance. Regenerative braking recovers 15 to 25 percent of energy on hilly routes and dramatically cuts brake wear. The TE8L carries an 8-year or 4,500-cycle battery warranty, and the CATL LFP chemistry is known for long cycle life and thermal stability. A diesel on HVO keeps its engine, exhaust aftertreatment, oil changes and filter costs. Over a 5-year, 600,000 km life, maintenance savings of $0.02 to $0.05 per km are realistic for the EV, adding $12,000 to $30,000 of lifetime saving on top of the energy gap.
Infrastructure is the swing factor. HVO needs no depot investment beyond a fuel contract. The TE8L needs charging: a DC fast charger doing 20 to 80 percent in 45 to 90 minutes costs $20,000 to $80,000 installed depending on power, plus any grid upgrade. For a single-truck operator, that upfront can erase the per-km saving; for a 10-truck depot, it spreads thin and the EV wins decisively, especially when night-rate electricity is available.
The EV case lives or dies on the electricity tariff. A depot that can negotiate $0.05 to $0.10 per kWh, or that adds solar plus storage, makes the TE8L unbeatable on operating cost. A depot stuck at $0.18 per kWh with no charger and no grid headroom should not force an EV onto a lane it cannot serve. The practical test is simple: take your annual km, multiply by 1.3 kWh per km, multiply by your tariff, and compare to diesel-plus-HVO cost. If the EV line is below, electrify that lane; if not, run HVO and revisit when the tariff improves.
Resale risk is often overstated for EVs. The TE8L's LFP pack is durable, and an 8-year warranty transfers confidence to the second owner. Diesel on HVO faces its own risk: if HVO supply tightens or a city bans combustion, the diesel's value falls. A blended fleet hedges both. Buyers should also note that many tenders now score zero-tailpipe vehicles higher, which can win contracts worth more than the residual difference, an angle pure cost models miss.
Consider 20 tractors each running 80,000 km per year on a 300 km regional loop. On HVO at $1.10 per L and 0.34 L per km, fuel is about $29,900 per truck per year, or $598,000 for the fleet. On the TE8L at $0.09 per kWh and 1.3 kWh per km, electricity is about $9,360 per truck per year, or $187,200 for the fleet, a saving of roughly $410,800 annually before maintenance. A shared charging hub at $400,000 installed is recovered in about one year on energy alone, after which the saving is almost pure margin for the operator.
The Morocco electric truck market suits a staged approach. The kingdom has growing renewable generation and industrial corridors around Casablanca, Tangier and Kenitra where depots and predictable routes make the TE8L practical, while HVO or fossil diesel can cover long cross-border legs to sub-Saharan neighbors where charging is thin. A Moroccan fleet can start with HVO on the hard lanes and electrify the fixed ones, reducing risk while building charging infrastructure and driver confidence.
There is no single winner. HVO is the fastest, lowest-capital decarbonization and a genuine bridge fuel. The TE8L electric tractor beats it on cost per km and tailpipe CO2 wherever cheap charging and predictable duty exist, and the maintenance and regen advantages compound over the truck's life.
A practical transition rarely flips the whole fleet at once. Start by mapping every lane by daily km, charging access and electricity price. Lanes that are predictable, depot-based and under 300 km round trip move to the TE8L first; lanes that are long, erratic or charger-poor stay on HVO. Re-map every six months as chargers are built and HVO prices move, and shift more volume to electric as the case strengthens. This staged method keeps service levels stable while the saving compounds, and avoids stranding capital in a premature full conversion that the depot cannot yet support with reliable power.
HVO's price tracks biofuel feedstock and policy, and supply can tighten during demand spikes, leaving a fleet exposed. Running a diesel on HVO as a bridge, rather than retiring the diesel, preserves optionality: if HVO gets scarce or pricey, the same truck runs fossil diesel, and if chargers arrive, the diesel is redeployed to the hardest lanes. The TE8L then takes the clean, cheap corridors. This hedge is especially useful in markets where the electricity tariff is still being negotiated, because it prevents a forced EV commitment on a lane the numbers do not yet justify and keeps the operation moving through supply shocks.
The balanced fleet plan is to deploy EVs on the routes that fit and keep HVO or diesel for the rest, rather than betting the whole operation on either technology at once.
