Developing solutions for underground storage of hydrogen in salt caverns (H2SALT).

Project description

The technology for underground hydrogen storage is currently undeveloped in both Spain and across Europe, and there are presently no locations for this type of storage. As such, the aim of H2SALT is to research into and develop the necessary technological solutions for the underground storage of hydrogen in salt caverns.

The project will be the result of collaborative work between the different consortium members, namely four specialised companies (Team Ingeniería, Tubacex, Tubos Reunidos and Tamoin) and Iberdrola as an organisation interested in the potential of the project findings. This consortium, together with the contribution of Tecnalia and Tubacex Innovación, the work to be done by the Energy Cluster and SIDEREX (responsible for the communication and dissemination of results) and the know-how of experts at the IGME (Spanish Geological and Mining Institute), will ensure that the H2SALT initiative can call on a multidisciplinary team capable of managing a global project for hydrogen storage in salt cavities.

The main objective of the project is to develop an integral system for hydrogen storage in a salt cavern in line with the prevailing geological conditions, and to determine the technical and economic feasibility of such a system for industrial projects. This includes the structural and behavioural analysis of the gas in the cavern, the tubular products for injection-extraction, the auxiliary facilities required to treat the gas upstream and downstream of the cavern, and the development of a business model.
