ICCT briefing paper estimates infrastructure cost and buildout required for 100% sales of zero-emission tractor-trailers by 2040

A new working paper from the the International Council on Clean Transportation (ICCT) estimates the order of magnitude in scale and pace of national infrastructure investment required to meet the goal of 100% sales of zero-emission tractor-trailers (Class 7 and Class 8)—battery-electric and fuel-cell electric—by 2040.

For battery-electric trucks, the results include the number and type of charging stations needed in each year. For hydrogen fuel cell trucks, the results include the total number of hydrogen refueling stations needed in each year. The result is an estimate of the total up-front public and private sector investment needed to deploy this scale of charging and refueling infrastructure.

The ICCT team modeled the future growth and activity of the US tractor-trailer fleet, and then made further projections for the two zero-emission powertrains: battery-electric and hydrogen fuel cell electric. The share of vehicles allocated to each of these two powertrain types was determined based on the estimated daily range required of vehicles in each vehicle category. . . .

For charging needs, they assume direct current (DC) chargers at three nominal power levels: 100 kW (overnight chargers), 350 kW (fast chargers), and 1,000 kW (megawatt chargers), coupled with a variety of optimized charging strategies.

For hydrogen fuel cell trucks, they assumed that the average hydrogen refueling station will have the capacity to deliver 4,800 kg of hydrogen per day.

Among their findings:

The national fleet of Class 7 and Class 8 tractor-trailers will grow by 3.5% in the next 30 years, totaling around 3 million tractor-trailers in 2050. Sales are projected to remain stable at around 145,000 units over the same period.

By 2030, approximately 127,000 charging points and 2020 hydrogen refueling stations will be necessary to support a fleet of 103,000 zero-emission tractor trailers. The cumulative investment needed to install publicly available infrastructure is $6.4 billion, beginning in 2021. Of 32,000 publicly accessible chargers, 14,000 will require a charging speed of 350 kW or greater.

By 2050, the network of national charging points will need to support a fleet of 2.4 million zero-emission tractor trailers. This will require 2.5 million charging points and 6,900 hydrogen refueling stations, while the cumulative investment in publicly accessible infrastructure will need to equal approximately $122 billion.

Total cumulative public and private investment through 2050 is estimated to be $238 billion.
