Description
A truck loaded with hydrogen came off the road on, crashed into a guardrail and overturned on the embankment.
The driver was taken to hospital with minor injuries. No other cars were involved in the accident.
The tanks were almost empty, with only a residual non-quantified amount of hydrogen.
A specialised company was called for the removal of the trailer.

Lesson Learnt

Lesson Learnt

The rollover did not caused hydrogen release. This speak for a sound design of the compressed hydrogen storage system. From the photos does not result any evidence of damage to the tubes. A much more sever test would have been a crash affecting the rear of the tubes.
It is unclear if the statement regarding no leak is based on measurement or on visual inspection of the pressure control system.
