Infrastructure to support a 100% zero-emission tractor-trailer fleet in the United States by 2040

The authors estimate how many electric vehicle (EV) chargers and hydrogen filling stations will be needed in the United States by 2040 to meet 100% sales of zero-emission tractor-trailers. By 2030, around 127,000 EV charging points and 220 hydrogen filling stations will be necessary to support a fleet of 103,000 zero-emission tractor-trailers. The investment to install public charging infrastructure is $6.4 billion, beginning in 2021. Of 32,000 public chargers, 14,000 will require a charging speed of at least 350 kilowatts (kW). By 2050, the national network of charging points must support a fleet of 2.4 million electric tractor-trailers, requiring 2.5 million charging points and 6,900 hydrogen filling stations, while the required cumulative investment will be about $122 billion. Most of the investments will support overnight charging. Most chargers will be installed in private depots, with growing private investment in the depot charging infrastructure coming to about $116 billion through 2050. Public overnight chargers at truck stops by 2050 would need about $20 billion of increasing investment. Because of the long-distance travels of tractor-trailers, overnight chargers will not be enough to meet the energy needs of the fleet. Filling these needs will require public fast chargers at truck stops with power levels of up to 1 megawatt (MW). The growing investment by 2050 on such 350 kW and 1MW chargers will be about $76 billion. For tractor-trailers traveling more than 650 miles per day, a network of hydrogen filling stations at a cumulative cost of $26 billion, or 21% of the total, may be needed though only 12% of the fleet would use them. Public investment would speed the installation of charging infrastructure, though most of the cost could be met by private investors after 2030. Government incentives for installation of infrastructure, with guaranteed public charging along crucial highways, would initiate deployment before 2030. Earlier arrival of government support would speed the market growth for zero-emission tractor-trailers.
