Deep Dive into Green Hydrogen: CLEANHYPRO Experts Master Four Core Electrolysis Technologies

The CLEANHYPRO consortium recently concluded a highly specialised two-day Workshop in Dresden, Germany, hosted by our partner Fraunhofer IFAM. This intensive training session was devoted entirely to the four core electrolysis technologies that form the foundation of our project: Alkaline Electrolysis (AEL), Proton Exchange Membrane (PEM) Electrolysis, Anion Exchange Membrane (AEM) Electrolysis, and Solid Oxide Electrolysis (SOEC).

Enhancing Expertise Beyond Specialisation

The goal of the workshop was clear: to ensure every consortium member has a deep, mutual understanding of the technological landscape we are working to accelerate. Experts from each respective field shared detailed insights, carefully explaining the technical differences and individual advantages of each method to an international audience.

AEL (Alkaline Electrolysis): A mature and reliable technology known for its low cost and long lifespan.
PEM (Proton Exchange Membrane) Electrolysis: Highly dynamic and compact, making it ideal for direct coupling with fluctuating renewable energy sources like solar and wind.
AEM (Anion Exchange Membrane) Electrolysis: A promising technology that combines the high performance of PEM with the lower material costs of AEL.
SOEC (Solid Oxide Electrolysis): The most energy-efficient technology, operating at high temperatures to produce hydrogen using less electricity.

As the participants exchanged knowledge, they enhanced their expertise beyond their own specialisation. This collaborative approach is expected to significantly facilitate the future close collaboration within CLEANHYPRO, ensuring a seamless approach to innovation.

From Knowledge to Industrialisation

The cross-technology understanding achieved in Dresden is vital for the success of our Open Innovation Test Bed (OITB). It ensures that when external companies—particularly innovative SMEs—apply through our Open Calls seeking support for their specific component or material (TRL 4–7), our consortium can provide holistic, integrated expertise across the full spectrum of electrolysis solutions.

Ultimately, by mastering these four core methods, CLEANHYPRO is positioning Europe to industrialise green hydrogen production faster and more efficiently.
