Published by California Energy Commission | State of California | Catalog Last Checked: July 31, 2026 at 08:44 PM | Dataset Last Updated: March 11, 2026 at 03:59 PM
Medium- and heavy-duty (MDHD) zero-emission vehicle (ZEV) hydrogen refueling and charging station data was collected from the following agencies: California Air Resources Board (CARB), California Energy Commission (CEC), CALSTART Inc., California State Transportation Agency (CalSTA), California Department of Transportation (Caltrans), California Transportation Commission (CTC) and San Diego Gas & Electric (SDGE).  “Chargers” (charging): Typically high-powered (150 kW or more) direct current fast chargers (DCFCs) for simultaneous charging at each location. “Dispensers” (hydrogen): Typically 700-bar dispensers for simultaneous refueling at each location. “Nozzles” (both charging/hydrogen): Connector that latches to the ZEV for charging or refueling.Following data fields are included:Charging or Hydrogen: Whether the station is classified as charging or hydrogenCharger or Dispenser Count: Number of chargers for DCFC and number of dispensers for hydrogenNozzle Count: Number of nozzlesAddress: Location of the stationLatitudeLongitudeFunding Agencies: Agency/agencies that have provided funding for building the stations
