Nel has published a dedicated status update and Q&A site to address the incident at the Kjørbo hydrogen station. The site can be accessed on www.nelhydrogen.com, and will be updated as new information becomes available.


Oslo, June 17, 2019 Nel ASA (Nel, OSE:NEL) announces new findings from safety consultancy Gexcon regarding the incident at the Kjørbo hydrogen station on June 10, 2019.

The preliminary Gexcon investigation shows that the incident started with a hydrogen leakage from the high-pressure storage unit and that a ‘cloud’ of hydrogen ignited. The investigations continue in order to identify the root cause of the leak as well as the source of the ignition.

“Based on further investigations, we can say with certainty that the leak started in the high-pressure storage unit, and we are now carrying out investigations to understand the detailed mechanisms of the leakage as well as what caused the ignition,” says Geirmund Vislie, Vice President Consulting of Gexcon.

Together with the authorities, Nel and Gexcon are conducting an off-site examination of the high-pressure storage unit, which comprises of both tanks and components from third-party suppliers and various components designed by Nel. Various tests and analysis have been initiated and will continue until the parties have a clear understanding of exactly where and how the leak started. Further investigations and data simulations will also look into the source of the ignition.

The low-pressure steel and composite storages were neither the source of the leak, nor the source of the ignition. No tanks ruptured in the incident.

Please see attached illustration of the site, including the highlighted high-pressure storage, which is now the main focus of the investigation.

“We can now conclude that Nel’s core technologies were not the source of the leakage. However, we are still searching for what ignited the hydrogen. We are grateful for all the parties that are working hard day and night to uncover the root cause of the incident, and are happy to see that good progress is being made,” says Jon André Løkke, CEO of Nel.


Oslo— Nel ASA (Nel, OSE:NEL) announces preliminary findings from safety consultancy Gexcon regarding the incident at the Kjørbo hydrogen station on June 10, 2019.

“Based on what we have seen at the site, we can conclude that neither the electrolyzer nor the dispenser used by customers had anything to do with this incident. We will continue to analyze the other components of the site to further narrow down the source,” says Geirmund Vislie, Vice President Consultant of Gexcon AS.

In addition to the electrolyzer and the dispenser used by customers, the Kjørbo site comprises of a stationary low-pressure storage unit, a low-pressure transport unit, a stationary high-pressure storage unit, various valve panels, and a hydrogen refueling station unit.

The Kjørbo site also includes a containerized, pressurized alkaline electrolyzer that produces hydrogen in part from solar power. This is delivered by the Nel Hydrogen Electrolyser division.

“We are pleased with the preliminary findings, and our electrolyzer division will now return to business as usual,” says Jon André Løkke,


Current status

Safety is Nel’s main priority and the company is working intensively to identify the root cause of the incident. Expert personnel are currently on the scene and actively contributing to the ongoing formal investigation. In addition, Nel has engaged independent fire and explosion safety consultants from Gexcon, who are on site and taking an active role to provide an independent incident report.
