The H2BASQUE project is developing a prototype for the generation of green hydrogen using PEM electrolysis.

At a time when green hydrogen is being held as the mainstay of the economy of the future, the race to democratise its use requires many developments. CIDETEC Energy Storage is participating in the H2BASQUE Project, where it is working on key components of technologies for the generation of green hydrogen at a competitive cost, such as water electrolysis or thermochemical cycles.

In relation to water electrolysis, the project will address the development of components for alkaline and acidic polymer electrolyte membrane electrolysis technologies, AEM and PEM, respectively. In addition, economically viable inorganic and organic thermochemical cycles for hydrogen generation in the lowest possible temperature range (< 500 °C) will be developed.

Within the H2BASQUE Project, CIDETEC coordinates the PEM Electrolysis Activity.This line develops key components of the technology, such as membrane electrode assemblies (MEA), catalysts, the separation membrane and the bipolar plate. The ultimate goal of the proposed development is to reduce the cost of the hydrogen produced, reduce the use of critical materials and improve the performance of the hydrogen production process.

In the final phase of the project, thanks to the developments obtained, a prototype will be available for the generation of green hydrogen using PEM electrolysis.

Funded by the ELKARTEK programme, in addition to CIDETEC Energy Storage, the project involves Tecnalia (coordinator), CICenergiGUNE, University of the Basque Country (UPV/EHU), Tubacex, Petronor, Tekniker and the Basque Energy Cluster.
