Geological hydrogen storage, like today’s natural gas storage, is needed to store variable renewable energies and flexibly provide green hydrogen mobility, industry, and residential uses. The purpose of the EU-funded HyPSTER project is to demonstrate the industrial-scale operation of cyclic H2 storage in salt caverns to support the emergence of the hydrogen energy economy in Europe in line with overall Hydrogen Europe road-mapping. The specific objectives are to:

•Define relevant cyclic tests to be performed based on modelling and the needs of emerging hydrogen regions across Europe

•Demonstrate the viable operation of H2 cyclic storage for the full range of use-cases of emerging European hydrogen regions

•Assess the economic feasibility of large-scale cyclic H2 storage to define the roadmap for future replication across the EU

•Assess the risks and environmental impacts of H2 cyclic storage in salt caverns and provide guidelines for safety, regulations and standards

Microbiological consumption of hydrogen and potential generation of hydrogen sulfide has been identified as one of the potential risks related to hydrogen storage in salt caverns.

Together with Equinor, we in NORCE will address this risk with a microbiological assessment of the cavern brine before and after the hydrogen storage. This will provide valuable information about in-situ microbiological activity after hydrogen exposure over several months. We will further investigate the overall microbial community and how it will be affected by the contact with pure hydrogen over several months.

UHS is a concept for large-scale energy storage where excess hydrogen is pumped and stored in different deep geological formations. Salt caverns, aquifers and depleted hydrocarbon deposits (gas reservoirs) in the North Sea can be used for this type of storage. There the hydrogen can stay for days, weeks or months, until it is needed. When it is pumped back, it can be either directly used or transformed into electricity later. This means, UHS is like a big battery in 1000-meter depth! Also, it is very safe because the storage formations are so deep and oxygen-free, there is no risk for humans or nature.
