Project funded by the Department of Economic Development, Sustainability and Environment of the Basque Government (ELKARTEK 2022 Programme)

EKARRIH2 is funded by the Basque Government’s Department for Economic Development, Sustainability and the Environment (ELKARTEK 2022 programme).


EKARRIH2 aims to develop advanced liquid hydrogen carriers and hydrogenation and dehydrogenation technologies suitable to transport a high volume of hydrogen over long distances at competitive costs and in a more environmentally sustainable way.

This project also intends to improve the scientific, technological and commercial position of the Basque Science and Technology Network and of Basque companies in the hydrogen sector in general, and in green hydrogen transport and distribution technology in particular.


Development of ionic liquids as advanced liquid hydrogen carriers.

Development of several different hydrogenation and dehydrogenation technologies.
Development of key components for said technologies: catalysts, electrodes or membranes.
Comparison of liquid hydrogen carriers with other means to transport.
