Hydrogen Fueling Station Design Standards
A large number of possible codes and standards can come into play for permitting design and construction of hydrogen fueling stations. Additional federal, state, and local requirements may also apply.
Model code provisions related to general design issues include:
The safety of employees and customers depends on proper design, location, and operation of storage and dispensing equipment and the proper installation and operation of leak detection, fire detection, and fire suppression equipment. In addition, incompatible materials or improperly installed equipment can lead to fuel contamination, which can degrade the performance of the fuel cells that power hydrogen-fueled vehicles. Model code provisions related to equipment specifications include:
On-site production
Fire safety equipment
Dispensing, operations, and maintenance safety equipment
Storage and compression equipment
- Compressed hydrogen gas storage
- Liquid hydrogen storage
- Compression systems and equipment
- Vaporizers
- Canopy Tops
Dispensing
- Hoses and connectors
- Liquid dispensers
- Gaseous dispensers
- Vehicle connectors
- Electrical equipment
- Fuel lines
Balance-of-plant components
Model code provisions related to footprints for hydrogen fueling stations address where equipment is located and appropriate separation distances among equipment, systems, and external exposures include:
