In the latest CORDIScovery podcast episode from February 2026, our project manager Benedikt Hasibar spoke about EUH2STARS and why large-scale hydrogen storage is essential for Europe’s energy transition. 

If we can’t store renewable energy efficiently, we risk curtailing it during periods of oversupply - instead of using it when it’s really needed. Large-scale underground hydrogen storage can provide exactly that flexibility.

With Benedikt representing the underground dimension of hydrogen, the episode also covers interesting applications on the ground and above ground, discussed at the beginning of the episode by two experts in the fields of public transport and aviation.
