These will be repurposed into storage under the coordination of Enagás, which brings its expertise in energy transport and hydrogen infrastructure to integrate this capacity into Spain’s future energy system.
This initiative supports Spain’s ambition to become a key producer and exporter of renewable hydrogen. The caverns will provide a safe, flexible, and scalable solution for storing renewable hydrogen – supporting the network stability and helping address renewable electricity intermittency.
“This collaboration with Enagás underscores the European chemical industry’s strategic role in enabling clean energy solutions,” said Etienne Galan, President of Solvay’s Soda Ash and Derivatives business. “We are especially grateful to partner with Enagás, whose proven infrastructure expertise and strong commitment are accelerating green hydrogen development.”
Enagás CEO Arturo Gonzalo emphasised that: “This agreement is a key milestone in the development of Spain's hydrogen backbone. By combining our experience in energy infrastructure with Solvay’s industrial capabilities, we are laying the foundations for a robust and flexible hydrogen network that will help achieve both national and European decarbonisation goals and boost competitiveness.”
