Overview of the Trucking Industry (2025)

The U.S. trucking industry is a cornerstone of the economy, responsible for moving over 72% of the nation’s freight by weight, equating to more than 11 billion tons annually. It is valued at approximately $700 billion in the U.S. and $2.7 trillion globally, with projections to reach $3.4 trillion by 2030 at a 5.4% compound annual growth rate (CAGR). The industry employs over 3.5 million drivers in the U.S. alone and supports 8.4 million jobs overall, with 96% of fleets operating 10 or fewer trucks. Despite its critical role, the industry faces challenges such as driver shortages (estimated at 80,000 open positions in 2024), rising fuel costs, and increasing regulatory pressure to reduce emissions. Sustainability is a growing focus, with a shift toward alternative fuels and electric vehicles, though diesel remains dominant.

Number of trucks: 13.5 million (3 million semi-trucks, 10;5 million single-unit).

Cost of fuel: Trucking spends $40 billion/year on diesel.

Emissions: The trucking industry produces 27% of annual carbon emissions.

Engine life: Emission controls degrade efficiency and can cause early engine failure.

ACE engines eleminate fuel costs, extend engine life, and are emission-free.

ACE conversions typically pay for themselves in six months.

Market Size Calculation: Target Market

Total Class 8 Trucks: 2.97 million in the U.S. (2025 estimate).
Eligible for Retrofit: Assume 80% of trucks (2.376 million) are diesel-powered and suitable for retrofit, excluding new BEVs/FCEVs and incompatible older models.

Adoption Scenarios

Low Case (10% by 2035): 2.376 million × 10% = 237,600 trucks retrofitted.
Base Case (20% by 2035): 2.376 million × 20% = 475,200 trucks retrofitted.
High Case (50% by 2035): 2.376 million × 50% = 1.188 million trucks retrofitted.

Revenue per Unit

Price Range: $25,000 (low end, scaled production) to $35,000 (high end, early adoption).
Assumed Average Price: $30,000 per unit, reflecting a midpoint that accounts for economies of scale with a strong manufacturer.

Market Value Estimate (2025–2035)

Low Case: 237,600 trucks × $30,000 = $7.128 billion.
Base Case: 475,200 trucks × $30,000 = $14,256 billion.
High Case: 1.188 million trucks × $30,000 = $35.64 billion.
