Lessons Learned

The hydrogen facility does not meet industrial guidelines for facilities of this type, from the standpoint of (1) the separation distance needed between a hydrogen pipe break and the building ventilation intake to prevent buildup of a flammable or explosive gas mixture inside the enclosure, and (2) the separation distance needed to prevent damage to safety-related structures resulting from the explosion of an 8,000-scf hydrogen tank.

Safety concerns such as hydrogen leaks and storage tank detonations must be considered and used to create effective new construction designs which mitigate the consequences of such events. Existing buildings which house hydrogen storage tanks need to properly analyze all of the risks associated with the use and storage of such systems.

Key:

  • = No Ignition
  • = Explosion
  • = Fire
