Green hydrogen is widely regarded as a key energy carrier for a climate-neutral future, but safely storing and transporting this gas remains a major technical challenge due to its extremely low molecular weight and high diffusion rates. Addressing this issue, an international consortium involving Pannon University has developed advanced polymer-based materials designed to significantly reduce hydrogen permeation and prevent material degradation, extending the lifespan of critical components by over 20 percent compared to current industry standards.
The project employs cutting-edge artificial intelligence and multi-scale modelling techniques, ranging from molecular simulations to full-scale component digital twins, to rapidly identify optimal polymer formulations. This innovative approach minimizes the need for costly and time-consuming physical experiments. Researchers aim to produce elastomers and thermoplastics with at least 10 percent lower hydrogen permeability, meeting the growing demands of the hydrogen economy.
Funded by the European Union’s Horizon and national innovation programs, the initiative supports the EU’s “Fit for 55” climate package by promoting safer, more durable, and cost-effective hydrogen infrastructure. The project will deliver standardized polymer materials certified for high-pressure hydrogen applications, establish open-access digital databases for industry and academia, and facilitate technology transfer to European and international industrial partners.
Pannon University, alongside partners from Germany, Belgium, and Austria, is driving this transformative research that not only enhances the technical viability of green hydrogen but also strengthens Europe’s leadership in sustainable energy innovation. The project, which started in May 2025 and will run through 2028, marks a significant step toward a cleaner, more sustainable energy future.
