- Description
A dual phase hydrogen tanker was expected to refill the storage of a refuelling station for buses. Due to the failure of a bolt of the tanker pump, the refuelling could not take place. This resulted is that buses were unable to fuel for 3 days and loss of operations during this window. The faulty bolt was replaced.

- Post-event summary
The tanker was expected to deliver hydrogen to top up the gaseous hydrogen storage over the weekend. Due to the failure, the delivery could not take place.
Because of the lack of fuel in the storage, corresponding approximately to six fills, it was decided to keep the fuel cell buses out of service until a new dual phase hydrogen trailer arrived. This caused lack of service for two days. Buses returned to service once it was confirmed that a new dual phase hydrogen tanker would be arriving in time for fuelling .
