H2SALT Project Advances Hydrogen Storage Solutions in Spain
The H2SALT project showcases the viability of hydrogen storage in salt caverns, enhancing operational flexibility and competitiveness for renewable hydrogen production. This strategic initiative supports the European energy transition, with projections indicating significant hydrogen project expansions by 2040.

The H2SALT project, led by Team Group and involving Iberdrola, Tamoin, Tubacex, and Tubos Reunidos, focuses on hydrogen storage in salt caverns to enhance production competitiveness in Spain. Presented on March 12 at the European Hydrogen Energy Conference in Seville, findings indicate that shared storage infrastructure can optimize operational flexibility for hydrogen production, reducing the levelized cost of hydrogen (LCOH).
This flexibility enables electrolysers to operate efficiently during low electricity cost periods and provides ancillary services to grid operators, enhancing overall grid stability. As Europe aims for a significant increase in hydrogen production capacity by 2040, the demand for storage solutions will escalate to ensure a stable supply across various industries. The project has secured €1.66 million in funding under the PERTE ERHA programme to foster technological advancements in this area.
