Tubos Reunidos Group has participated in the European Hydrogen Energy Conference (EHEC) 2026, held from 11 to 13 March at the Seville Conference and Exhibition Centre (FIBES II), one of Europe’s leading forums dedicated to hydrogen.
As part of the conference, the H2SALT Project Results Presentation Workshop: Hydrogen Storage in Salt Caverns showcased the main outcomes of the H2SALT project, developed over the past three years the PERTE Hydrogen Value Chain programme.
During the session, Marcelo López Belver, Business Development Manager at Tubos Reunidos, presented the project’s progress alongside Victoria Astigarraga Ruiz de Velasco, PhD Research Engineer at TUBACEX, focusing on the development of hydrogen injection and withdrawal systems and their auxiliary components.
The H2SALT project is led by TEAM Ingeniería and involves Tubos Reunidos Group, Tubacex Tubos Inoxidables (TTI), Tamoin and Iberdrola, with the collaboration of the Basque Energy Cluster and SIDEREX – Cluster Association of the Steel Industry. Its objective is to research and develop the technological solutions required for the safe, efficient and large-scale underground storage of hydrogen in salt caverns.
Hydrogen storage remains one of the key challenges of the energy transition. Although hydrogen has a high energy density by mass, its low volumetric density makes large-scale storage complex. In this context, salt caverns represent one of the most promising solutions, enabling the storage of large volumes of hydrogen at moderate pressures and competitive costs.
Within this technological challenge, Tubos Reunidos focuses on developing seamless steel materials and pipes capable of operating under the demanding conditions found in salt caverns, where hydrogen, brine and associated gases are injected and withdrawn. These developments are essential to ensure the safety, reliability and durability of underground hydrogen storage infrastructures.
The H2SALT project also addresses key challenges such as the characterisation of salt formations, hydrogen interaction with materials and rocks, leakage prevention and the definition of technical specifications for storage systems.
Beyond its technological scope, H2SALT has a significant strategic impact on the hydrogen economy, contributing to industrial decarbonisation, energy system integration through storage, and the development of new business opportunities for the industrial sector.
Tubos Reunidos’ participation in EHEC 2026 reinforces its commitment to developing innovative solutions that support the energy transition and positions the company as a key player in the hydrogen value chain.
