Release from a compressed storage of an optics component plant The leak was observed on the hydrogen storage consisting of 19 racks of 16 cylinders each. Rescue teams set up a security perimeter and a specialized company inspected the leak.The activity of the establishment were interrupted during the night and resumed the next morning.

The event occurred in an atmospheric pressure tank storing effluents. The plant was in the production phase. The head of the overfill prevention valve located at the top of the tank was thrown a distance of 77 m. The tanks shell was deformed (curved downward) but not leaking. Employees noted a noise similar to the opening of a valve, and a low-pressure alarm in the tank appeared in the control room, despite the fact that the level and temperature were normal.

A fire started on the brakes of a truck carrying hydrogen. Due to the risk of extension of the fire to the hydrogen, the fire brigade install an emergency area until the fire is extinguished.There has been no release of hydrogen.

During a patrol, an operator detects a hydrogen leak in a refinery on a footbridge 30 meters high. The origin of the leak is identified 4 days later on a pipe under insulation. The operator proceeds to remove the insulation (under SCBA). The leak is located at the level of a reinforcing saddle. The installation is shut down and put under nitrogen. Thickness measurements and radiographic checks are used to characterise the nature of the crack defect. A leak sealing system (SOFM) is put in place while awaiting the removal of the pipework for assessment during the next shutdown.

A petroleum refinery experienced a catastrophic rupture of a heat exchanger in the catalytic reformer / naphtha hydrotreater unit (the NHT unit). The heat exchanger, catastrophically ruptured because of High Temperature Hydrogen Attack.Highly flammable hydrogen and naphtha at more than 500 degrees Fahrenheit (260C) were released from the ruptured heat exchanger and ignited, causing an explosion and an intense fire that burned for more than three hours.

A hydrogen and fuel cells bus experienced a hydrogen detection alarm in a city centre. This triggered the evacuation of the immediate surroundings and the towing of the vehicle to the maintenance garage.

This near miss occurred at a CHP plant operation with a SOFC. During the heating phase, the SOFC stopped due to the opening of the mainpower switch.This was due to a contact problem inside the SOFC module, but the reason was not clear at first.

A vehicle overlooked into a road, overlooking the presence of another vehicles. The latter tried to avoid the accident by crossing to the other lane, occupied by a FCEV. The car was hit in the front.

The FCEV driver did hit a pole with the left front at a relative low speed.

A truck conventional truck moved to another lane and did not see the FCEV. The collision caused a total loss to the latter.
