FEBRUARY 1, 2025: First Anniversary
On the 1st of February, we marked 1 year since we first met as a consortium to kick off the CirculH2 project. One year more of working towards a sustainable future with hydrogenases applied in industry. 🧪
I would also like to take this opportunity to present a bit more about us, CirculH2 and its importance, to a broader audience in the following months, starting here:
Why hydrogenases?
Enzyme-based biotechnology is a powerfool tool for producing chemicals, however, many processes still rely on fossil ressources and inefficient bio-based materials. In contrast, chemical industry has already optimized the energy use by incorporating H2 as a clean and efficient energy carrier. But traditional H2 catalysts such as noble metals lack selectivity and biocompatibility that is needed for enzyme-driven reactions.
Nevertheless, recent breakthroughs in hydrogenase research to replace tranditional H2 catalysts has created a paradigm shift: Hydrogenases, nature’s catalyst for H2 conversion, are highly selective and have energy efficiencies that compete with those of precious metals. NiFe- and FeFe-hydrogenases have been discovered and engineered to efficiently regenerate key cofactors, making them valuable for industrial biocatalysis.
With the high activity, scalability, and ideal properties of hydrogenases, the perspective for their large-scale deployment in enzyme-based biotechnology has opened up and serves as a sustainable alternative to conventional chemistry.
📌 TLDR: Hydrogenase research breakthroughs enable enzyme-based biotech to harness H2 as an energy carrier, making biocatalysis more efficient and sustainable.

APRIL 28, 2025: Publication Alert! Switching the Cofactor
Can we use NADH instead of NADPH to drive enzymatic carboxylic acid reduction for the synthesis of industrially relevant compounds? Yes, we can!
Have a look at this work by our partner Margit Winkler from the TU Graz, recently published in the special collection of ChemCatChem “Women of Catalysis 2024”. 👩🔬
This is a great example of women driving the field of biocatalysis forward! 🧪

OCTOBER 29, 2024: Publication Alert! Reviews on Hydrogenases
Have a look at this review exploring methanogenesis in wastewater treatment that highlights the role of hydrogenases in methane production by our partner University of Zagreb Faculty of Chemical Engineering and Technology! Hydrogen activation by hydrogenases in methanogenesis enables the efficient biogas production and supports circular economy by turning organic waste into renewable energy!
They’ve also published a second review on hydrogenases—the key enzymes in our project—exploring their types, sources, and potential for industrial application in biocatalytic cascades for green hydrogen processes.

OCTOBER 21-23, 2024: [FeFe]-H2ase Workshop at the TUM
We recently wrapped up the Hydrogenase Workshop at the Technical University of Munich Professorship of Electrobiotechnology organized by Nicolas Plumere and Kelly Lim-Trinh.
The sessions covered both theory and lab work on the expression and handling of [FeFe]-hydrogenases, led by Jan Jaenecke, Martin Winkler, and Kasia.
Discussions centered around the potential applications of hydrogenases in future industrial processes, particularly in sustainable energy and biotechnology.
We welcomed participants from both industry and academia, including EvoEnzyme, Enzymicals AG, and Axxence, as well as representatives from the University of Zagreb / Sveučilište u Zagrebu, Delft University of Technology, and Technische Universität Graz. Each of them also held a presentation on the potential applications of hydrogenases, exploring how these enzymes could be scaled up for industry and used sustainably for future technologies.
Apart from the scientific aspect, we enjoyed informal conversations over great dinner with everyone. Thank you for participating and we look forward to meet again at the consortium meeting next year! 🔜
