Enapter has unveiled a new AEM electrolyser stack designed to serve in 100MW-plus installations, marking a significant increase in both the company’s system capacities and the broader scale ambitions of AEM electrolysis.
The German firm’s Stack 250 is ten times larger than its predecessor and can produce around 100kg of hydrogen per day.
Until now, the company has largely focused on small, modular AEM systems ranging from single-kilowatt units up to low-megawatt platforms. Its 2.5MW Nexus platform comprised its largest AEM system.
AEM electrolysers across the market have also typically sat in the kW range, with emerging systems peaking at around 5MW.
Available in a containerised or skid-mounted format, Enapter said the Stack 250 is compatible with alkaline electrolysis systems – enabling hybrid combinations to optimise efficiency across intermittent renewable power sources.
Dr Jürgen Laakmann, CEO of Enapter, said the new system meets the rising demand the firm has encountered for electrolysers in the megawatt range.
Enapter saw a with receivable impairments and returned stacks pushing EBIDTA losses of €18.1m ($21.3m).
AEM remains a nascent hydrogen production technology. While it’s pitched as a low-capex alternative that can achieve the small footprint and flexibility of PEM without the use of precious metals or PFAS, its remains susceptible to degradation.
