Hydrogen technologies could be one of the pillars of future European energy and transport systems


Hystories research project focused on the possibilities of storing hydrogen in porous reservoirs, such as depleted gas or oil fields and aquifers. Hystories developed technical solutions and produced socio-economic analyses to support the deployment of underground hydrogen storage.

This project ran from January 1st, 2021, to June 30th, 2023. Find below our synthesis on major project outcome and proposed implementation plan.



SUBSURFACE TECHNOLOGY DEVELOPMENT : Technical developments are still needed to validate pure hydrogen storage in porous media, particularly in terms of bio- and geo-chemical impacts or on the identification and ranking of trap candidates at European scale.

TECHNO-ECONOMIC FEASIBILITY : Future underground hydrogen storage and transportation network being infrastructure assets that typically require a decade to develop, it needs planning, social acceptability and financial security. Hystories has developed insights to inform decision makers in government and industry that will face these deployment decisions.



The Hystories project stems from a cooperation of European public entities (universities,
research centers) and private entities (consulting firms, industrial actors), grouped in a consortium led by Geostock, an underground engineering company. This European partnership consists of 7 main partners, 17 third-party entities, as well as an advisory board composed of 13 industrial operators in the gas market. These actors come from 17 countries:
Austria, Belgium, Croatia, Czech Republic, Denmark, England, Estonia, France, Germany, Greece, Italy, Norway, Poland, Portugal, Romania, Spain, Turkey.



Over two and a half years, 37 deliverables have been published and are available on this website. Scientific communication in peer-reviewed journal are also available in open access, as long as a link to two Web GIS.
