The PureH2 project, with H2SITE and Enagás as project partners, awarded over 2 million euros in funding from the IDAE for its innovative green hydrogen storage system.

The PureH2 project, based on optimising purification systems for green hydrogen storage in salt cavities, has been awarded 2,089,014 euros in funding by the Institute for Energy Diversification and Saving (IDAE).

The project partners, coordinated by Enagás, are the consultancy firm CRS Ingeniería, the energy company Trinity Energy Storage, H2SITE, the manufacturer of hydrogen separation units based on palladium alloy membrane technology, and the mining company Iberpotash (ICL Iberia). PureH2 falls within the framework of the aid programme for the innovative renewable hydrogen value chain of the Recovery, Transformation and Resilience Plan, part of the NextGenerationEU package financed by the European Union.

With a duration of 36 months and a total budget of 2,888,719 euros, PureH2 will help gain a wider insight into the potential development of future hydrogen storage in saline cavities in the geological area of the Ebro Basin.

The project focuses on developing a purification solution for hydrogen stored in salt cavities by using and comparing different membrane technologies (palladium and carbon), once the hydrogen has been extracted. Membrane technology is new and, depending on the type of application, can be much more efficient than existing systems such as PSA (Pressure Swing Adsorption).
