Hamburg-- Enapter AG (ISIN: DE000A255G02) has concluded a core partner agreement with the Dutch energy company Adsensys B.V. (“Adsensys”). As a core partner, Adsensys will receive stacks from Enapter. These core components of every electrolyzer for the production of green hydrogen will be used by Adsensys in the future to build its own electrolyzer in the megawatt range. These Adsensys AEM electrolyzer will then bear the addition “AEM powered”, an Enapter brand that refers to Enapter’s patented AEM-stacks in the electrolyzer.

Adsensys plans to implement AEM-powered electrolyzers in hydrogen projects with a total electrolysis capacity of 10 MW for customers by 2026. The electrolyzer will be controlled by Enapter’s EMS software (Energy Management System), which will be licensed and labeled for Adsenys as part of the core partnership. Enapter expects the first revenues from stack sales to be realized as part of this core partnership from 2025. In addition, this core partner agreement will commercialize the Enapter software for the first time.

 

Dr. Jürgen Laakmann, CEO of Enapter: “Our first core partnership is only a short time after our strategy adjustment and is clear evidence of the growth course we have embarked on. Enapter is fully focused on its core competence of stack production, while third-party suppliers can use our technology to build their own electrolyzer. In addition, the first commercialization of our software marks another milestone.”

Helmholtz-Zentrum Berlin für Materialien und Energie

A team has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium.

 

Hydrogen will play a major role in the energy system of the future, as an energy storage medium, a fuel and valuable raw material for the chemical industry. Hydrogen can be produced by electrolysis of water in a virtually climate-neutral way, provided this is done with electricity from solar or wind power. Scale-up efforts for a green hydrogen economy are currently largely dominated by two systems: proton-conducting membrane electrolysis (PEM) and classic liquid alkaline electrolysis. AEM electrolysers combine the advantages of both systems and, for example, do not require rare precious metals such as iridium.

Alkaline Membrane (AEM) Electrolysers without Iridium

Now, research teams from TU Berlin and HZB, together with the Department of Microsystems Engineering (IMTEK) at the University of Freiburg and Siemens Energy, have presented the first AEM electrolyser that produces hydrogen almost as efficiently as a PEM electrolyser.

Instead of iridium, they used nickel double hydroxide compounds with iron, cobalt or manganese and developed a process to coat them directly onto an alkaline ion exchange membrane.

Insight into molecular processes during electrolysis at BESSY II

During the electrolysis in the cell, they were able to carry out operando measurements at the Berlin X-ray source BESSY II at the LiXEdrom end station.

A theory team from Singapore and the USA helped to interpret the experimental data.

'This enabled us to elucidate the relevant catalytic-chemical processes at the catalyst-coated membrane, in particular the phase transition from a catalytically inactive alpha phase to a highly active gamma phase and the role of the various O ligands and Ni4+ centres in the catalysis,' explains Prof.

Peter Strasser, TU Berlin. 'It is this gamma phase that makes our catalyst competitive with the current state-of-the-art iridium catalysts.

Our work shows important similarities to iridium in the catalytic mechanism, but also some surprising molecular differences.'

The study has thus significantly advanced our understanding of the fundamental catalysis mechanisms of the new nickel-based electrode materials. In addition, the newly developed coating method for the membrane electrode promises excellent scalability. A first fully functional laboratory cell has already been tested at IMTEK. The work lays the foundation for further industrial evaluation and demonstrates that an AEM water electrolyser can also be highly efficient.

Strasser. High-performance anion-exchange membrane water electrolysers using NiX (X = Fe,Co,Mn) catalyst-coated membranes with redox-active Ni–O ligands. Nature Catalysis, 2024; DOI: 10.1038/s41929-024-01238-w

Recent efforts in anion-exchange membrane water electrolysis (AEMWE) focus on developing superior catalysts and membrane electrode assemblies to narrow the performance gaps compared with proton-exchange membrane water electrolysis (PEMWE). Here we present and characterize Ir-free AEMWE cells with NiX (X = Fe, Co or Mn) layered double hydroxide (LDH) catalyst-coated membranes with polarization characteristics and hydrogen productivities approaching those of acidic PEMWE cells, achieving >5 A cm−2 at <2.2 V. Operando spectroscopy revealed a correlation between Ni4+ centres and redox-active O ligands with an O K-edge feature, attributed to µ3-O ligands in the γ-LDH catalytic phase via density functional theory calculations. This computational–experimental study challenges the previously assumed correlation between spectral O K-edge features and oxygen evolution reaction performance in Ni-based LDH catalysts and provides insights from the molecular to the technological level demonstrating how redox-active Ni–O species and innovative catalyst-coated membrane preparation boost AEMWE performance to values rivalling state-of-the-art PEMWE cell technology.

Verdagy has opened the first electrolyzer manufacturing facility in the United States supported by the U.S. Department of Energy (DOE). Located in Newark, California, the new Silicon Valley factory spans over 100,000 square feet and has the capacity to produce several gigawatts of electrolyzers.

 

The factory, first announced in 2023, was awarded a $39.6-million grant from the DOE in March 2024 to accelerate high-volume production of Verdagy’s advanced alkaline eDynamic® electrolyzers. Full-scale production is slated to begin in the first quarter of 2025.

 

Peter Cousins, COO of Verdagy, commented: “With deep experience in both utility-scale solar and automotive battery manufacturing, we knew the importance of designing and solving for scale from the very beginning. This motivated us to look end-to-end as we approached green hydrogen electrolyzer manufacturing.

 

“Verdagy partnered with ATI to optimize everything, with innovations from molten metal through coils to completed electrolyzer cells. Our new multi-gigawatt factory in California is intentionally simple, precisely what is needed to solve for the scale and fossil parity costs required to decarbonize hard-to-abate industries.”

 

Verdagy’s manufacturing process will begin with ATI’s metal coils and produce finished electrolyzer cells by vertically integrating subassemblies with minimal manual handling and processing. This streamlined approach, coined ‘Coils-to-Cells,’ was developed in partnership with ATI.

 

“ATI’s partnership with Verdagy is an ideal opportunity for our high-performing, high-quality materials in the specialty energy market,” said Tom DeLuca, President, ATI Specialty Rolled Products.

 

The ‘Coils-to-Cells’ manufacturing system aligns with the DOE’s goal of supporting domestic electrolyzer manufacturing through a domestic supply of metals, thereby fostering a ripple effect on domestic production.
