CALSTART, a leading clean transportation nonprofit, has updated its National Medium- and Heavy-Duty Zero-Emission Infrastructure Map, which now lists approximately 162 total infrastructure facilities in 17 states for medium- and heavy-duty trucks.

These additions are consistent with trends noted in CALSTART’s latest Zeroing in on Zero-Emission Trucks report, co-written by Trucks Project Manager Jacob Richard.

Enhancements to the map include:

• The addition of 64 new EV charging and hydrogen refueling sites.
• A new phasing-in strategy overlay showing how current charging availability compares with the broader network buildout projected in CALSTART’s Phasing in U.S. Charging Infrastructure Strategy. This is also consistent with the American Council for an Energy-Efficient Economy’s recent Pathways to Zero-Emission Freight report.
• Grid-capacity scenario layers showing projected peak load in 2026, 2030, and 2035, with managed and unmanaged charging scenarios that highlight where charging demand may place greater pressure on the grid and where additional planning or investment may be needed.

"This isn’t just a map of available ports; it’s a map of progress towards publicly available charging, which the industry needs to transition. The most detailed and accurate map on site features specific to trucking, it allows fleets and shippers confidence that these solutions will work with their needs,” said CALSTART’s program manager, Corridor Planning, Michael Joseph, lead author of the Phasing in U.S. Charging Infrastructure Strategy. “Fleets and shippers can also use it to shift plans to electrify sooner: They can connect with a public site developer to use their site if their own depot facilities are hampered by utility delays."

With this engaging tool, truck drivers can see where to access over 1,500 total EV charging plugs and 32 hydrogen refueling nozzles from leading operating organizations with a click of the mouse.

Background on the Infrastructure Map

Public and private charging networks are still maturing, making this a challenge to overcome for the next wave of zero-emission truck adoption, according to the latest Zeroing in on Zero-Emission Trucks report. While some key travel corridors, such as the I-5 or I-10, are ramping up public infrastructure development, other major highway systems, including I-80 and I-95, are still undergoing planning. Priority hubs based on freight volumes in Phase 1 are identified in the National Zero-Emission Freight Corridor Strategy.

Launched in 2024, CALSTART’s Medium- and Heavy-Duty Infrastructure Map helps truck drivers easily locate electric charging and hydrogen refueling stations from coast to coast and remains one of the leading publicly available U.S. resources for tracking key features related to truck charging; by doing so, this tool offers a more complete picture of charging availability.

“We work with the infrastructure providers to keep this map up to date,” said Jacob Richard. “Fleets need to know what charging or refueling stations are out there so that they can make informed decisions about acquiring zero-emission trucks for their fleet. We make sure that every station is quality-checked to be accessible for zero-emission trucks. Every station listed is available for fleets to use with confidence, and this is the only centralized map that truly provides that.”
