CRS Engineering, present at the Renewable Hydrogen and Underground Storage Conference (Pure H2). (2026)

November 6, 2026

The PUREH2 project, focused on the optimization of purification systems for the storage of renewable hydrogen in saline cavities, held its first event “Renewable hydrogen and underground storage” on June 4, 2026 at the E.T.S.I. Mines and Energy (UPM).

The event has been organized by the Official College of Mining Engineers of Central Spain (COIMCE), MINERGIA and the Higher Technical School of Mining and Energy Engineers (ETSIME-UPM). The meeting brought together professionals, companies and reference entities to share advances, experiences and projects linked to the development of renewable hydrogen and its underground storage. The conference allowed us to address, from a technical and applied perspective, some of the main challenges of the sector: the European decarbonization strategy, the deployment of hydrogen infrastructure in Spain, storage, certification and new hydrogen separation and purification solutions.

The project, PUREH2, which is financed by the IDAE (Institute for Energy Diversification and Saving), It has key partners: CRS Ingenieria, Trinity Energy Storage, H2SITE, Iberpotash (ICL Iberia) and Enagás as coordinator, working on the development of innovative solutions that guarantee the quality of stored hydrogen through advanced purification technologies.
