The company affected manufactures valves and other hydrogen-storage components, equipment tests. It has offers as well a testing laboratory. The accident happened during testing of a hydrogen tank. A dull bang and a huge pressure wave was felt kilometres away. News report massive damage to the test facility, but a very small fire. Still according to the news, the most probable cause emerging from the investigation is the over-pressuring of the tank due to an erroneous connection of a compressed air hose.

On a highway, a truck loaded with 400 gas cylinders crashed at night for an undetermined cause against a concrete wall and overturned. It slipped 150 m, before several 200 litre cylinders of hydrogen caught fire and set the truck on fire as well. The police stated that it was a large fire with detonations. The 400 gas cylinders were connected together and many of the cylinders had fallen out of their racks. In order to reduce the danger of further explosions, the fire-brigade cooled the gas cylinders with water for two hours. The highway remained closed for eight hours.

A hydrogen leakage caught fire in the hydrogen compressor area of the continuous reforming unit. The reforming unit and the hydrocracking unit were immediately stopped. The hydrogen flow was cut off, a protective combustion was carried out and the fire was completely extinguished after approximately 20 minutes, with no casualties. The cause of the accident is being investigated.

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.

This near miss occurred at a depot site with 20 fuel cell buses are operated by a local bus company. A hissing sound was heard coming from a hydrogen tank at the refuelling facility, and the local fire department was alerted.After roughly two hours, the fire brigade managed to close the main hydrogen supply, temporarily solving the problem, and local buses were able to resume their service, but were not able refill their H2 cylinders.

A hydrogen leak took place on a trailer carrying compressed hydrogen, located inside the fenced perimeter of a hydrogen station. According to the company managing the hydrogen delivery and refuelling station, the leak did not pose any risk to people or the environment. A preliminary assessment identified a faulty valve s source of the leak, but t was unclear a that time if it was a single defect or a systemic (i.e. design) problem.

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.

a gas leakage (approximately 70% hydrogen, 21% nitrogen and the rest carbon monoxide and other impurities) occurred at the connection between a temperature measurement casing and a flange in the carbonization workshop cleaning tower. The leakage was reported to the plant leader, who issued the request to the workers to use iron cards and rubber plates to plug the leak. The operation failed and the leakage continued. At 17:00, at the request of the plant leader, the workers used a tire inner tube to wrap the leak.

A mixture of mainly carbon monoxide and hydrogen was released from a pipeline transferring process gases in a not further specified unit of a chemical plant, generating a flammable mixture which ignited possibly due to static electricity and resulting in 22 deaths and 8 injuries.

In a residual-oil hydrotreatment unit (also called residual oil hydrogenation) plant, a hydrogenation unit caught fire with a huge bang, followed by a fireball in the form of a mushroom cloud. Black smoke began to billow up in the sky and was clearly visible from several kilometres away
