- Solvay and Enagás are developing a hydrogen storage hub in Polanco, Cantabria.
- The project repurposes salt caverns originally used for soda ash production.
- It aims to support Spain's renewable hydrogen production and export goals.
- The initiative enhances network stability and addresses renewable electricity intermittency.
Project Overview
Solvay and Enagás have partnered to develop a hydrogen storage hub in Polanco, Cantabria. This initiative will utilize salt caverns, initially created for soda ash production, to store renewable hydrogen. The project aims to integrate this storage capacity into Spain’s future energy system, leveraging Solvay's expertise in salt cavern infrastructure and Enagás's experience in energy transport and hydrogen infrastructure.
Strategic Importance
The development of this hydrogen storage hub supports Spain’s ambition to become a leading producer and exporter of renewable hydrogen. By providing a safe, flexible, and scalable storage solution, the project will enhance network stability and address the intermittency of renewable electricity. This initiative is a significant step towards achieving both national and European decarbonization goals.
Local and European Impact
Coordinated with local stakeholders, the project strengthens Solvay’s position as a key provider of salt cavern infrastructure in Europe. With a legacy of over 100 caverns in Germany, Solvay is now expanding its operations into Spain. The collaboration with Enagás is seen as a milestone in developing Spain's hydrogen backbone, combining industrial capabilities with energy infrastructure expertise to lay the foundations for a robust hydrogen network.
