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…
This resulted in the destruction of the building where the explosion occurred and claimed the lives of two people. The triggering event was a blowing out of a gasket in a water pump situated in a 100…
A Worner 1000 STU gas balloon, of German registry D-OAGH, piloted by a commercial pilot was substantially damaged during landing, when the hydrogen-filled envelope came in contact with a power line,…
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…
A pressure relief device (frangible burst disk) on one of a hydrogen delivery tube trailer`s 26 tubes failed prematurely and released hydrogen while filling a hydrogen storage tank at a government…
The laboratory works with soil bacteria that cannot survive in the presence of oxygen. As a result, research work is conducted inside a plastic chamber in which the chemical constituents in the air…
Motorway accident which involved a large quantity of vehicles and a gaseous tube trailer which transported gas hydrogen in pressure. Some cars were burning under the back part of the gaseous tube…
A pipe rupture occurred in a steam condensing line of a residual heat removal system at the Hamaoka Nuclear Power Station Unit-1 (Hamaoka-1) during operation at rated power. The reactor was manually…
A cryogenic hydrogen laboratory had a power outage. The cryogenic hydrogen storage was no longer being cooled, therefore temperatures and pressures within the storage system started rising. There…
A tractor - semitrailer with horizontally mounted cylinders filled with compressed hydrogen struck a northbound pickup truck that had veered in front of it.The tractor-semitrailer then went out of…
Near the end of the process of filling a gaseous hydrogen tube trailer at a liquid hydrogen transfilling station, a safety pressure-relief device (PRD) rupture disc on one of the tube trailers ten…
A hydrogen safety sensor went into alarm at a hydrogen demonstration facility. The early morning temperature was near freezing and there was a trace of precipitation on exposed surfaces. Upon further…
On February, 20, 1987, the Vogtle nuclear power plant reported a hydrogen leak inside the auxiliary building. This plant was recently licensed, had never been critical, and was in cold shutdown at…
This accident happened on the SS66 road and involved a trailer transporting compressed hydrogen cylinders. The 50 l cylinders were in packages of 16 cylinders each. Due to the breaking of fixing…
During the start-up of a propylene hydrogenation reactor, very high temperatures were generated in the catalyst bed. At the time, propylene and hydrogen were being fed to the reactor which contained…
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…
The event occurred just after that start-up steam was introduced into the reformer furnace inlet. At this moment an very high pressure and a single loud bang was reported by the operations personnel…
A 24" pipe carrying synthesis gas (Hydrogen = 43.5%, Nitrogen = 14.08%, Methane = 0.2%, Carbon Dioxide = 12.3%, Water = 29.3% by volume) ruptured. About 60 kg of hydrogen contained in the gas…
The release of a blast furnace gas occurred at a section of pipework, due to the rupture of valve seal. The gas did not ignite and the fire service attended as a precaution. The gas was both…
A gaseous tube trailer gone off road in a countryside area and landed on one side. All cylinders were loaded to a pressure of 200 bars. The impact with the ground has caused the rupture of a high…
