The 520-Bar GH2 Trailer Retrofit operates as a productized upgrade system within the gaseous-hydrogen distribution sector. This retrofit system replaces existing valves, vessel side skins, and thermal pressure-relief devices on 520-bar trailers. It converts the trailer configuration so individual storage vessels can be isolated independently, allowing a single vessel to be serviced without disabling the rest of the trailer. For enhanced ventilation safety, dedicated vent lines for each thermal pressure-relief device discharge gas directly at the roof level. The system provides an upgrade path for existing trailers in mobile fueling, backup storage, and distribution applications.

Use Cases

  • Mobile hydrogen fueling
  • Backup hydrogen storage
  • Hydrogen distribution trailers
  • Upgrading legacy gaseous-hydrogen trailers to the 520-bar retrofit configuration

Capabilities

  • Upgrades a hydrogen trailer to the verified 520-bar configuration
  • Allows individual storage vessels to be isolated
  • Routes thermal pressure-relief venting to roof level
  • Supports repair of an isolated vessel while other vessels can remain in service
  • Replaces specified trailer valves, side skins and pressure-relief devices
