Green hydrogen is a clean and renewable energy vector. The use of this gas as an energy source could transform our industry and mobility sustainably. Additionally, it can be considered as a solution for storing electricity produced by intermittent renewable energies. For instance, green electricity generated by wind turbines or solar panels could be converted into hydrogen through electrolysis, which could then be stored underground and finally reconverted into electricity, which would be injected back into the grid through fuel cell systems. This “Power to Gas to Power” scheme could mitigate the inherent intermittency of renewable energies. To accelerate the deployment of this value chain, it is necessary to find solutions for massive storage. Storage in porous media would open up very interesting possibilities for the European Union.
What is Hystories?
Hystories is an acronym that stands for “HYdrogen STORage In European Subsurface”. It is a scientific research project on the possibilities of storing hydrogen in porous environments, such as depleted gas or oil fields and existing aquifers. Hystories is a collective that brings together public actors (European universities, research institutes) and private actors (consulting firms, industrial and energy storage site operators) to develop technical solutions and produce socio-economic analyses on the possibilities of such geological storage.
This project, funded by the European Union and led by Geostock, ran from January 1st, 2021, to June 30th, 2023.
The conference presenting all the project work took place on May 25th and 26th, 2023, in the main auditorium of Mines ParisTech.
