Underground Energy Storage Operators (UESO) Joins Forces with H2eart for Europe to Advance Underground Energy Storage

Recognising the pressing challenge of climate change and the increasing use of intermittently produced
renewable energy sources (RES) by many EU member states, H2eart for Europe emphasizes the need for
clean storage options capable of providing necessary flexibility.
HyStorage first test phase successful – hydrogen extracted again after injection into porous rock

The first operating phase of HyStorage with a 5% hydrogen blend was successfully completed end of
January 2024. The partner companies presented the first interim results of the research project, which
examines the integrity of porous rock formations for the storage of hydrogen.
Billions must be invested in hydrogen storage this decade to provide long-term flexibility to future grids: industry group

A new industry group, H2eart for Europe, has warned in its launch report that between €18bn and €36bn ($19.5bn-39bn) will be needed to set up enough underground hydrogen storage systems to provide long-term flexibility for zero-carbon grids.
