Preliminary findings from the investigation into the recent explosion at a hydrogen station in Norway have found that neither the electrolyser nor the dispenser had anything to do with the incident.

Geirmund Vislie, Vice-President Consultant of safety consultancy Gexcon, said, “Based on what we have seen at the site, we can conclude that neither the electrolyser nor the dispenser used by customers had anything to do with this incident.”

“We will continue to analyse the other components of the site to further narrow down the source.”

In addition to the electrolyser 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 refuelling station unit.

The Kjørbo site also includes a containerised, pressurised alkaline electrolyser 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 electrolyser division will now return to business as usual,” said Jon André Løkke.

The Kjørbo hydrogen station, located just outside of Oslo, caught fire at around 17:40 CET on Monday (10th June).
