Fueling Technology

 

 

 

 

 

 

 

Fueling is Simple

Stations for cars are designed for consumer retail sales (accept credit cards, adhere to state standards for measurement and fuel quality). Stations for heavy-duty vehicles and material handling equipment may use a PIN or key to identify the person fueling.

 

When a vehicle operator activates the dispenser, hydrogen flows from the storage tanks to the dispenser and through the nozzle into the vehicle in a closed system. Initial safety checks ensure the integrity of the system before fueling starts. During the fill, the dispenser is designed to pause periodically for several seconds to conduct additional integrity checks, according to code and/or fuel protocol, and then resume filling. Most vehicles have a standardized communication system that sends parameters from the vehicle’s fuel storage system to the dispenser, which are used to calculate the pressure to stop the fill at a “full” tank. A car can fill up in less than five minutes.

Hydrogen Stations

Equipment

Hydrogen stations are in operation and under construction for light-duty vehicles (passenger vehicles), heavy-duty vehicles (trucks and buses), and material handling equipment. Stations dispense hydrogen as a compressed gas at pressures of 10,000 psi (H70) for light-duty vehicles and 5,000 psi (H35) for all other vehicles.

 

All stations generally have the same equipment, but station employs different designs depending on how the hydrogen is produced, delivered, stored and dispensed. Each station includes, at minimum:

  • Above-ground hydrogen storage equipment – based on the station’s location and capacity, hydrogen can be stored as a liquid, a low-pressure gas, or a high-pressure gas. Storage tanks follow ASME standards.
  • At least one compressor – Hydrogen is compressed to reduce volume and increase pressure. Typically, a compressor is used to replenish the buffer storage. Liquid and low-pressure storage tanks may use multiple compressors.
  • Chiller – Hydrogen is cooled as to not exceed the temperature threshold of the industry standard fueling protocol. (Stations for heavy-duty vehicles and material handling equipment may not use chillers.)
  • At least one dispenser – Dispensers look similar to gasoline dispensers. They may sit on the same island as other fuel dispensers, or sit on their own island. Dispensers for class 8 vehicles will be in there own islands, the same as diesel trucks.

Safety

Hydrogen is a non-toxic, environmentally benign natural element has been safely used in manufacturing for more than 90 years. It is a very small, diffusive molecule that is 14 times lighter than air. Like all fuels, hydrogen is flammable and safety systems at the station and in the vehicle are designed for hydrogen’s properties.

Hydrogen stations have standardized safety systems that include grounding, breakaway hoses, and fire sensors that are common for all fueling stations, plus sensors that measure pressure, temperature, and leakage of gaseous hydrogen. Stations are designed to safely vent hydrogen in case of an extreme emergency, such as a gasoline fire that increases the temperature of the stored hydrogen. Although the illustration shows a passenger vehicle, stations for heavy-duty and material handling vehicles use the same safety standards and systems.
