HYUSPRE Project

 The "National Hydrogen Strategy 2030", adopted by the Government and published on 23 May 2021, requires the examination of domestic natural gas storage reservoirs by 2030 to determine their suitability for storing hydrogen or hydrogen-enriched natural gas.  In Hungary, the absence of such an established review procedure means that there is currently no capacity or research experience to assess the hydrogen stability of storage reservoirs.


Addressing the challenges of hydrogen storage in porous rock has also been raised at EU level through a restricted call for proposals launched by the Fuel Cells and Hydrogen Joint Undertaking as the sponsor ("Sponsor"), to which the Hungarian Gas Storage Limited Company ("Hungarian Gas Storage Ltd." or “HGS" or "Company") was invited to join by the TNO project office leading the consortium.  The Sponsor is a public-private partnership (PPP), involving the European Commission, dedicated to promoting the research and development of fuel cell and hydrogen technologies in Europe with a view to achieving carbon neutrality. In total, 16 organisations joined the call for proposals launched by the Sponsor: TNO project office (based in the Netherlands) leading the consortium, 8 industrial participants (Centrica, EBN, NAFTA, RAG, Shell, SNAM, EQUINOR, NEPTUNE) in addition to HGS, 4 research institutes (TNO, Energy Institute Linz, Fondazione Bruno Kessler, FZ Jülich) and 3 academic institutions (University of Edinburgh, Clausthal University, Wageningen University).

 

Objectives:

In porous reservoirs:

o   to establish the methods to examine geochemical, microbiological and flow processes caused by hydrogen,

o   to develop a methodology to determine the recoverability of hydrogen and the extent of hydrogen loss,

o   to investigate the potential reservoir deterioration and gas well integrity.


 

o   To estimate the cost of hydrogen storage conversion and to identify potential business opportunities.

o   To identify underground gas storage sites where long-term hydrogen and hydrogen-enriched natural gas storage projects are feasible on a demonstration basis, including access to external EU funding.

o   As a result of the R&D project, to upgrade TLR level 3 (technology under laboratory conditions) to TLR level 5 (validation of hydrogen storage in porous rock under industrial conditions).

Implementation

The research programme will be implemented in 7 working groups, concurrently, each tasked with the following specific responsibilities:

  1. Study of hydrogen production, use and storage in the case of industrial actors
  2. Exploring geochemical reactions in the reservoir
  3. Microbiological activity in the reservoir
  4. Carrying out hydrogen flow studies in the reservoir
  5. Investigation of the durability and integrity of well structures and (cap and reservoir) rock.
  6. Integrated composition modelling based on the above to assess suitability for hydrogen storage
  7. Techno-economic assessment and preparing a roadmap




Expected Results

o   Complementing the Aquamarine Project to cover our underground storage processes

o   Establishing an international hydrogen benchmarking system

o   Further EU and national funding may be involved through the established cooperation

o   Playing a leading role in the development of both national and EU hydrogen strategies, and spearheading the launch of demonstration and R&D projects for the long term

o   Long-term R&D cooperation

o   access to international laboratories

o   building a new hydrocarbon field assessment framework,

o   enhancing professional expertise by integrating innovative technologies

o   innovative energy system modelling techniques

 

The findings could significantly advance the exploration of hydrogen storage potentials within HGS-operated storage facilities. In this context, it is significant that the project organically complements the HGS-led Aquamarine Project, since the latter focuses on assessing and readying the Hungarian natural gas infrastructure for the hydrogen integration, whereas this project concentrates on preparing the storage reservoirs for the same purpose.
