THE PROJECT

OPPORTUNITY

At a national level, underground storage is limited to natural gas, but there is some storage in saline cavities in Europe, although there is a certain lack of knowledge and limitations to having a large-scale, stable and leak-free hydrogen storage system.

THE CHALLENGE

H2SALT seeks to research and develop the necessary technological solutions for the safe, large-scale, efficient and cost-effective storage of underground hydrogen in salt caverns, in such a way that allows for technological growth and advancement.

Main Objective
Develop an integrated system for hydrogen storage in a salt cavern.

Structural and behavioural analysis of the gas in the cavern.

Tubular products for injection-extraction.

Necessary auxiliary facilities for the treatment of gas prior to its entry and after its removal from the cavern.

Development of a business model.

Ultimate Objective
Obtain an underground hydrogen storage solution in salt caverns.



Feasibility study and conceptual design.

Characteritation of the salt formations on the peninsula.

Development of materials and systems (injection – extraction, auxiliary facilities, etc.).

Business model for industrial projects.
