Five Enapter AEM Electrolyser Stacks in a testing setup

About AEM Electrolysis

Enapter’s core technology is the patented Anion Exchange Membrane (AEM) Electrolyser.

We are the pioneers and market leader of commercialised AEM Electrolysers and at the forefront of R&D for AEM Electrolysis.

What are the benefits of AEM Electrolysis?

Unlike PEM electrolysers, AEM electrolysers need no titanium corrosion protection, nor costly iridium. Our standardised production also leverages significant cost advantages. They likewise avoid the downsides of alkaline technology: most importantly, that it is less able to cope with the load changes and dynamics of intermittent renewable energy.

AEM Electrolysis compared with Alkaline electrolysis and PEM electrolysis

Our AEM technology combines the best of PEM and alkaline electrolysers.

High operational flexibility

Its hydrogen output range matches energy fluctuations of renewable electricity sources.

Fast response time

Quick ramp-up/ramp-down in response to these changes in energy load from intermittent renewables

Price stability

AEM Technology avoids the use of expensive raw materials like iridium, promoting price and supply chain stability.

Future-proofed

AEM membranes and ionomers/binders do not require the use of non-degradeable PFAS materials, enabling AEM to comply with upcoming PFAS restrictions

Pioneering AEM Electrolysis

AEM Electrolyser technology first came to life through the Italian R&D firm ACTA S.p.A in 2009, before Enapter took over the core tech, patents and electrochemistry team in 2017.

As the world’s leading developer and manufacturer of AEM electrolysers, Enapter builds on more than 20 years of AEM experience with a strong R&D team advancing AEM technology.

H2 Dezentral Study - KeyVisual

Decentralized Green H2 Production

Study: H2 Dezentral

Decentralised H2 concepts that produce green hydrogen from renewable energies will be an increasingly important building block for climate neutrality and energy supply security in the future. Read more about how AEM Electrolysers fit in this study plublished by German Energy Agency dena.

Iridium and the Green Hydrogen Economy

Will Iridium shortage slow down the energy transition?

As demand for hydrogen rises, concerns about Iridium scarcity grow. Delve deeper into this widely discussed topic and learn how a surge in demand could cause supply shortages and higher costs, potentially slowing the green hydrogen transition.
