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.
