The challengeTwo transitions
Two transitions
One materials challenge
The hydrogen economy needs reliable steel. Circular production needs recycled materials. CIRHY brings these transitions together to engineer steels that are both sustainable and resistant to hydrogen damage.
Make variability
Build confidence
in performance
Investigate hydrogen–microstructure interactions to help prevent embrittlement and support reliable steels for demanding applications.
Predict first
Design better
Connect advanced experiments with physics-based modelling to move beyond trial-and-error materials development.
Our approachFrom atomic interactions
From atomic interactions
to industrial impact
CIRHY is developing a predictive, digital design framework that connects knowledge across scales. Experiments and modelling work together to reveal how circular steels behave in hydrogen environments.
