EDITOR'S NOTE: After this article was published, Cummins subsequently revealed the number and model of the affected electrolysers to Hydrogen Insight. Click here for the latest information.
Cummins has confirmed to Hydrogen Insight that it is recalling “a small number” of electrolysers produced by its Accelera segment (formerly Hydrogenics), owing to technical problems with that particular series.
“We are working with our technical team to resolve this issue as quickly as possible to minimize the impact on the customers affected,” a spokesperson told Hydrogen Insight.
While the US conglomerate has not disclosed which model is being recalled, Hydrogen Insight understands that the 2.5MW PEM electrolyser installed in December 2021, as part of the Green Hysland project on the Spanish island of Mallorca, is one of the units involved.
This would imply that an early series of the Accelera HyLYZER, the only PEM electrolyser the manufacturer offers, is the model that is experiencing technical problems.
However, Cummins has also not disclosed what issue has been identified with the series, only noting that it is limited to that specific model.
“We are confident in our electrolyzer portfolio overall, as the majority of our electrolyzers are operating normally,” the spokesperson said.
The company has also not confirmed how many electrolysers were affected, nor responded to allegations on social media that around 30 units have been grounded for more than a year with no offer to fix or replace the equipment.
Although Cummins has built an electrolyser order book worth more than $500m and 3.5GW of manufacturing capacity, the Accelera segment is projected to make a loss of $420m-440m by the end of the year due to continued investment into new hydrogen and battery-electric products and facilities.
