Enapter develops multicore electrolyzer with AEM


Enapter expands its product portfolio to the megawatt-class with the multicore electrolyzer with AEM. The final development of the new model has begun, further reaching the innovative potential of anion exchange membrane (AEM) technology. Multicore AEM will be introduced to the market next year, allowing low-cost, flexible and reliable production of green hydrogen.

Enapter will reduce the cost of green hydrogen through the mass production of standardized products. The AEM Multicore is no exception: it will feature 440 mass-produced central electrolyzer modules, the “AEM batteries”, in a complete system that can produce ~ 450 kg of hydrogen per day. This is the energy equivalent of about 9.5 barrels of crude oil. With this modular approach, AEM Multicore offers an affordable alternative to traditional megawatt-class electrolysers, while being highly responsive to fluctuations in the renewable electricity supply.

Sebastian-Justus Schmidt, President, Enapter AG, said: “AEM ​​Multicore will be cheaper than comparable PEM electrolysers, and the use of mass-produced AEM battery modules makes the difference. The modular approach makes the whole system more accessible but also significantly more robust and extremely flexible. This makes it ideal for using intermittent renewable energy.”

Its multi-core approach also offers reliability advantages over conventional systems. If a battery module fails, it can be replaced in a few simple steps, while the “plant balance” system that supports hydrogen production also has built-in redundancy. Its unique modularity allows AEM Multicore to flexibly adjust production levels in response to changes in the supply of renewable energy.

Enapter, is approaching AEM’s full potential to accelerate the adoption of green hydrogen energy with the construction of its mass production facility, Campus, in Saerbeck, is scheduled to start this fall and is expected to end and start operating in 2022. With that, AEM Multicore will be ready to make a considerable contribution to the rapid increase in the capacity of the electrolyser. With Campus’ planned annual production capacity of 280 MW, more than 5% of its goal could be achieved every year.
