Medium and Heavy Duty Infrastructure

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 hydrogen
• Charger or Dispenser Count: Number of chargers for DCFC and number of dispensers for hydrogen
• Nozzle Count: Number of nozzles
• Address: Location of the station
• Latitude
• Longitude
• Funding Agencies: Agency/agencies that have provided funding for building the stations
