Showcasing the pathways and values of underground hydrogen storages

Artelys has been selected by GIE to undertake an in-depth analysis of the values brought by underground hydrogen storage, and to illustrate how these values can emerge in a selection of territorial use-cases. To proceed with the identification of the values brought by hydrogen storage, Artelys has taken into account the flexibility needs that are specific to electrolytic hydrogen, and considerations related to the nascent nature of the hydrogen economy. Artelys has relied on the multi-energy modelling platform Artelys Crystal Super Grid to evaluate the level of benefits brought by hydrogen storagte in four territorial use-cases, including reduction of levelized cost of hydrogen production, avoided investments, reduction of GHG emissions, reduction of RES curtailment. The results of this study can help inform policy recommendations to support the emergence of underground hydrogen storage that can help kick-start a cost-efficient and sustainable hydrogen ecosystem.
