HyStorIES: Hydrogen Storage In European Subsurface
Renewable hydrogen combined with large scale underground storage enables transportation of energy through time, balancing out the impacts of variable renewable energy production. While storing pure hydrogen in salt caverns has been practiced since the 70s in Europe, it has never been carried out anywhere in depleted fields or aquifers.
Technical developments are needed to validate these two solutions. As subsurface technical feasibility studies for a future hydrogen storage in depleted field or aquifer will be site-specific, as for other geology related activities, HyStories will provide developments applicable to a wide range of possible future sites: the addition of H2-storage relevant characteristics in reservoir databases at European scale; reservoir and geochemical modelling for cases representative of European subsurface, and tests of this representativeness by comparing it with results obtained with real storage sites models; and lastly an extensive sampling and microbiological lab experiment programme to cover a variety of possible conditions.
Complementarily, techno-economic feasibility studies will provide insights into underground hydrogen storage for decision makers in government and industry. Modelling of the European energy system will first define the demand for hydrogen storage. Environmental and Societal impact studies will be developed. For a given location and hydrogen storage demand, a high-level cost assessment for development of each of the competing geological storage options at that location will be estimated, and the sites will be ranked based on techno-economic criteria developed within the project. Finally, several case studies will enable consideration of the implementation of potential projects, notably by considering their economic interest.
This will provide substantial insight into the suitability for implementing such storage across EU and enable the proposition of an implementation plan.
- Enhance the characterization of the underground aquifers or depleted fields at European scale, largely built for CO2 geological storage capacity assessment, to characteristics specific to hydrogen storage;
- Identify the suitability of the reservoir structures that can be found in European subsurface for hydrogen storage, assess the mixing aspect when the structure is a depleted fields;
- Identify geochemical reactions that can alter stored hydrogen purity in the underground, at the batch scale and at the reservoir one;
- Carry out an extensive test programme of microbiological brines and rock samples from porous media reservoirs, thanks to the support of gas storage operators to provide data;
- Recommendation on completion materials to be used in underground hydrogen storage facilities;
- Define a hydrogen storage need at Member State level, at various time horizons (prior to having a hydrogen transportation system, and assuming one develops);
- Assess the regulatory framework at the EU level;
- Analyse the environmental and socioeconomic impacts of the project Estimate the costs of developing an underground hydrogen storage in aquifer, depleted field or salt cavern for any of the possible stores;
- Estimate the costs of developing an underground hydrogen storage in aquifer, depleted field or salt cavern for any of the possible stores;
- Rank the storage sites based on their development costs and technical aspects from the technical feasibility work;
- Case studies to analyse the economic opportunity for several locations;
- Development of an implementation plan for Underground Storage of Renewable Hydrogen in EU by 2050.
