HYPRAEL analysis: does Berkeley’s AEM breakthrough threaten or validate alkaline electrolysis (AEL) leadership?

Posted on by

Experts at HYPRAEL evaluate the impact of UC Berkeley’s new AEM electrolyzer design on durability and cost. Discover why AEL technology remains the most viable and scalable choice for industrial green hydrogen production.

The global clean energy community is buzzing about the recent announcement from UC Berkeley regarding a significant milestone in Anion Exchange Membrane (AEM) electrolyzer technology. The research claims to have mitigated the crucial issue of polymer degradation, potentially lowering manufacturing costs dramatically. This development, while impressive, requires careful strategic context. As specialists in Alkaline Electrolysis (AEL), HYPRAEL recognizes the importance of the research, yet we must underscore the proven maturity of AEL. This article details the key differences, the strategic market response, and why AEL continues to hold the industrial advantage in longevity, tested efficiency, and current scale. Read on for our detailed technological comparison.

AEM’s theoretical cost vs. AEL’s industrial reality

While the cost reduction potential of AEM is appealing, the technology must now transition from lab success to multi-megawatt industrial reliability—a threshold AEL has surpassed for decades. AEL, by utilizing robust and inexpensive liquid electrolytes, avoids the high material costs associated with some membrane systems, making its operational expenditure (OPEX) highly competitive over the long term. This operational stability, essential for continuous industrial output, is the critical advantage AEM must still prove.

Why longevity and efficiency drive HYPRAEL’s AEL strategy

The key metric for industrial-scale deployment is the total cost of ownership (TCO). The long lifespan and established recycling processes of AEL components contribute significantly to its lower TCO. HYPRAEL remains focused on refining AEL’s efficiency curve and further reducing its capital expenditure (CAPEX) to maintain our edge. The Berkeley study, by tackling durability, highlights the fundamental engineering trade-offs inherent in all electrolysis methods.

The hydrogen future: a strong market built on strong competition

HYPRAEL views the progress in AEM as beneficial for the entire green hydrogen sector. Increased competition fosters innovation and validates the global commitment to electrifying fuel production. Our message is clear: the technology is mature, the investment is urgent, and Alkaline Electrolysis (AEL) is the reliable choice for today’s large-scale projects.

Alkaline electrolysis: 8% of european publications confirms its technological dominance

Posted on by

HYPRAEL, a leader in alkaline electrolysis (AEL) solutions for green hydrogen production, welcomes the publication of The Hydrogen Education and Research Landscape report (October 2025). The report highlights the relevance and growing attention the European scientific community is dedicating to alkaline technology.

The analysis, which tracks publications and patents across Europe (EU27, EFTA, and UK) from 2006 to 2025, reveals that alkaline electrolysis accounts for 8% of the total publications identified in the fields of clean hydrogen production, storage, and fuel cells.

The focus shifts to production

This data point is critical, as the study notes a “growing emphasis on publications and patents related to hydrogen production.”

AEL, being the most mature, proven production technology with lower manufacturing costs (as it does not require precious metals as catalysts), is positioned as the most robust and cost-effective solution to meet the increasing demand for green hydrogen at industrial scale.

The report also highlights the presence of alkaline technology in the fuel cell sector, where it accounts for 5% of publications.

HYPRAEL invites media and industry stakeholders to review the full report and visit its website to explore how its state-of-the-art alkaline electrolysers are optimising efficiency and lowering the cost of green hydrogen.

HYPRAEL: the project that wants hydrogen to breathe pressurized?

Posted on by

In European laboratories, driving high pressure green hydrogen production, where steel pipes intertwine like arteries and steam sketches invisible maps in the air, teams of engineers are driven by a shared obsession: to free hydrogen — as much as possible — from its dependence on mechanical compressors. Learn more about the project’s foundations on the  .

This isn’t science fiction. It’s HYPRAEL, a project that sounds futuristic but is being built, quite literally, with hands in the present. Its goal is as bold as it is concrete: to produce green hydrogen directly at pressures beyond today’s state of the art, drastically reducing the need for mechanical compression afterward.

When the challenge is invisible, but heavy: compression

Today, producing hydrogen isn’t the main issue. The real challenge comes next. To store or transport it, it must be compressed. And that costs energy, money, and time. HYPRAEL aims to skip that step — or at least, make it much smaller.

The alkaline alchemy

The chosen technology isn’t new, but the ambition behind it is. Alkaline electrolysis has been used for decades, but it has never been pushed this far: to operate above 30 bar, to explore its limits and aim for 50 or even 80 bar of pressure, while also improving efficiency at higher temperatures — with advanced, sustainable materials and minimal loss in performance. It’s like asking a bicycle to compete with a bullet train… and win. Discover the full scope of the initiative through its listing on .

But the researchers aren’t intimidated. They’re redesigning cells, testing new electrodes and separators, and fine-tuning each parameter like a symphony. Because they know that if this works, it could change the rules of the game.

Beyond the lab

HYPRAEL doesn’t stop at academic papers. It’s grounded and focused on the industry. The project will validate prototypes under real-world conditions, measure environmental and economic impact, and work toward a future where Europe not only consumes green hydrogen — but produces it with homegrown technology.

A European effort, built together HYPRAEL is not a solo endeavor — it’s powered by a consortium of leading institutions and companies across Europe. Coordinated by the Aragon Hydrogen Foundation, the project brings together key players such as Fraunhofer, Green Hydrogen System, AGFA, VECO, and Syensqo. Each partner contributes its expertise: from advanced materials and cell design to industrial validation and process engineering. This collective effort ensures that HYPRAEL’s innovations are not only technically sound, but scalable, sustainable, and aligned with Europe’s vision for clean hydrogen production.

HYPRAEL makes progress and plans ahead at Steering Committee Meeting

Posted on by

HYPRAEL makes progress and plans ahead at Steering Committee Meeting. The HYPRAEL project’s Project Steering Committee (PSC) convened in Milan, Italy, on February 21-22nd, 2024. This meeting served two key purposes:

  • Oversee and validate the overall direction and policy of the project.
  • Foster collaboration and knowledge sharing among partners.

During the meeting, each partner presented their progress in fulfilling their assigned roles within the project. Additionally, the team discussed various challenges encountered so far and strategized solutions for addressing them as the project moves forward.

Beyond the formal meeting, the partners gained a firsthand look at Syensqo’s facilities. This visit provided valuable insights into their expertise and contributions to the project.

The HYPRAEL consortium remains dedicated to achieving its primary goal: drastically reducing the energy consumption associated with hydrogen production. The collaborative efforts and shared knowledge gained at the PSC meeting will undoubtedly propel them closer to this crucial objective.
