The FCEV was travelling at approx. 75 km/h (80 km/h speed limit) on a straight, downhill part of the road. Another vehicles was waiting at a STOP sign on the right side, did not see the incoming FCEV and drove into the road at the moment of the FEV passing. The second vehicle hit the FCEV on the back right side. There were only body parts damaged and no hydrogen was released. There was no oil or other fluid spillage and no people were injured.The diagnostic system of the FCEV did not issue any alarm, and there were no warning lights to indicate a problem with the hydrogen systems on-board.

The incident involves a gas booster provided by a manufacturer. This device is used in the experimental platform of the project to raise the pressure in pipelines from 60 to 80 barg (from 6 to 8 MPa), allowing the gas to flow in a close loop. After 5 weeks of operation, a critical gas leakage through the vent port was detected.At the moment of the incident, the compressor was working with a mixture of hydrogen and methane (H2/CH4 blend 20/80 %v/%v). The booster was sent to the manufacturer for inspection and reparation. Severe damage in the seals of the vent port was found.

The fire developed an early morning on a hydrogen bus at a refuelling station for public transport. The fire Department was called to site responding to reports of a fire on the property. A section of the highway was closed as firefighters.According to the bus company release, one bus was destroyed and the dispenser of the hydrogen fuelling station was damaged. The stationary hydrogen storage and the rest of the Explosions were heard and seen from the tanks on the bus that had just been filled.

DISCLAIMER: this event description is unsatisfactory. Details on the system and the real incident evolution are (still) missing. The incident affected a prototype light hydrogen vehicle in a hydrogen research centre of a university. The vehicle was a kind of a four-wheeled scooter. The fire started on the vehicle while being filled. Apparently, the hydrogen storage system was a hydrogen hydride. The site was evacuated and the building isolated from its hydrogen supply. The firefighters attacked the fire with a hose and extinguished it one hour later.

The vehicle was being driven in traffic at low speed when it was struck from behind by a full-size pickup which forced the fuel-cell vehicle forward into another pickup. No hydrogen was released and no one was injured.The vehicle was extensively damaged on both front and rear ends and later declared a total loss. A vehicle data analysis indicates that the vehicle and controls operated as designed.

The accident occurred at a production, distribution and storage station for hydrogen city busses. After filling the hydrogen cylinders of a bus, the hydrogen detection system of the bus triggered an alarm. The site technician pushed the emergency button and the station was put in safety mode. The technician in charge of filling disconnected the hydrogen hose that connects the station to the bus. The maintenance manager of the bus manufacturer was alerted and arrived 20 minutes later and evacuated the personnel. They closed the valves of the on-board storage system.

The hydrogen bus was in the workshop. The fire started on the bus and expanded to the shed, which was containing also a conventional bus. Due to the presence of hydrogen, the fire brigade intervened only from outside the shed. During the fire, loud bangs could be heard from time to time inside, caused by exploding tires, as reported by Omroep Gelderland.

A hydrogen and batteries driven aircraft was forced to land after a flight incident. According to the aircraft company the aircraft was forced to an emergency landing, but landed normally on its wheels in a flat grass field and almost came to a stop, but was damaged as it caught the left main gear and wing in the uneven terrain at the end of the field at low speed.According to the sources, the flight conformed to the approved test route over the airport, and that the aircraft structural integrity was maintained throughout the incident sequence.

According to the media news, the accident involved an explosion of a fuel cell driven forklift during driving, resulting in an employee's death and 6 light injured other employees. The fire did not spread. This has been confirmed by an OHSA investigation (see references), which however does not specific any cause and responsibility.

The boat was performing a drive test when one of the 280 lead gel batteries exploded and took fire. The local fire brigade was able to extinguish the fire but the above deck section of the boat was extensively damaged. According to Volger and to Wannemacher (see references), the automatic fire-alarm system of the hydrogen storage and the fuel cells were "brought in a safe state" and did not suffered any damage.
