A new ICCT analysis estimates the number of charging points and hydrogen refueling stations needed to enable the transition to 100 percent sales of zero-emission Class 7 and Class 8 tractor-trailers by 2040 in the United States. By 2030, approximately 127,000 charging points and 220 hydrogen refueling stations will be necessary to support a fleet of 103,000 zero-emission tractor-trailers.
