HyLife – Microbial risks associated with hydrogen underground storage in Europe

Hydrogen underground storage is a good option to store large quantities of hydrogen for our future green society. But did you know that there are many microorganisms living within these sites? And many could actually feed on hydrogen? Up until now, we don’t really know who they are and how fast they will be.
In our HyLife project we will sample, analyze and characterize many different potential storage sites all over Europe with a focus on the microbial effects at the different sites . By discussing and aligning our methods between labs, we will be able to work on many samples simultaneously and compare results. We will also establish microbiological models and try to understand the effect on business decisions. With this we hope to find key factors for selecting sites and make safe and resilient hydrogen storage in the subsurface possible.
