HyUnder - Hydrogen Underground Storage at large scale: Case study Spain
Energy Procedia, 2015Co-Authors: J. Simon, A. M. Ferriz, L. C. CorreasAbstract:Hydrogen as an energy carrier is understood as a system capable of storing energy for a later use in a controlled manner. Surplus electricity from renewable energy serves for green Hydrogen generation via electrolysis. Once produced, the Hydrogen is stored for later consumption. This paper describes the Spanish Case Study of the HyUnder project which aims to evaluate the potential of Underground Hydrogen Storage for large-scale energy Storage along Europe, analysing besides the Spanish Case, France, Germany, the Netherlands, Romania, and the United Kingdom. This case study has considered for the assessment, the competitiveness of Hydrogen Storage against other large scale energy Storage concepts, the geological potential for Hydrogen Storage in the region, how to embed the Hydrogen energy Storage in the energy market and the possible business cases in four different applications: transport, Power to Gas, re-electrification and industry, taking into account all the economic aspects such us the electrolyser OPEX and CAPEX or the cavern, electricity and water costs. It is shown that the Spanish geology can provide four technical options for Hydrogen Underground Storage. Results have shown the interest of the technology in short - medium term especially linked to certain conditions of high intermittent renewable energy penetration in the Spanish power grid that result in surplus or residual electricity. Hydrogen Storage is interesting because it can integrate renewable energy systems in other sectors which do not have overcapacity and a high use of fossil fuels as the natural gas sector and the transport sector. Moreover, all the economic issues have been analysed for two different horizons, 2025 and 2050; concluding that the average price of electricity is the main cost. From the financial results, transport application represents a business case which, although in order has enough values of Hydrogen demand to be stored, combination of different applications must be needed in order to make sense to the development of the cavern.

Hydrogen Underground Storage petrographic and petrophysical variations in reservoir sandstones from laboratory experiments under simulated reservoir conditions
International Journal of Hydrogen Energy, 2018Co-Authors: Steven Flesch, Daniel Albrecht, Dieter Pudlo, Arne Jacob, Frieder EnzmannAbstract:Abstract Fluctuating energy production by renewables is one of the main issues in transition times of energy production from conventional power plants to an energy production by renewables. Using excess produced electricity (windy/sunny periods) to convert water to oxygen and Hydrogen and storing the Hydrogen in depleted oil-, gas fields or sedimentary aquifer structures would provide the option to recover and convert Hydrogen to electricity in periods with an energy demand. Research focus is here the pore space in the geological Underground where still few studies exist. In static batch experiments up to six weeks long, under different reservoir-specific conditions; regarding pressure, temperature and formation fluid salinity, sandstones were exposed to 100% Hydrogen. Before and after these experiments microscopic, petrophysical and computer tomography analyses are conducted. The preliminary results from different scales (μm to cm) and dimensions (2D and 3D) of 21 samples indicate that Hydrogen Underground Storage is likely possible.

Hydrogen Underground Storage in siliciclastic reservoirs - intention and topics of the H2STORE project
EGU General Assembly, 2013Co-Authors: Dieter Pudlo, Viktor Reitenbach, Hilke Würdemann, Leonhard Ganzer, Michel Panfilov, Axel Liebscher, P. Pilz, Daniel Albrecht, Michael Kuhn, Steven Henkel, Marco Lucia, Michael Kuehn, Reinhard GauppAbstract:The transfer of energy supply from nuclear and CO2-emitting power generation to renewable energy production sources is strongly reliant to the potential of storing high capacities of energy in a safe and reliable way in time spans of several months. One conceivable option can be the Storage of Hydrogen and (related) synthetic natural gas (SNG) production in appropriate Underground structures, like salt caverns and pore space reservoirs. Successful Storage of Hydrogen in the form of town gas in salt caverns has been proven in several demonstration projects and can be considered as state of the art technology. However, salt structures have only limited importance for Hydrogen Storage due to only small cavern volumes and the limited occurrence of salt deposits suitable for flushing of cavern constructions. Thus, regarding potential high-volume Storage sites, siliciclastic deposits like saline aquifers and depleted gas reservoirs are of increasing interest. Motivated by a project call and sponsored by the German government the H2STORE ("Hydrogen to Store") collaborative project will investigate the feasibility and the requirements for pore space Storage of Hydrogen. Thereby depleted gas reservoirs are a major concern of this study. This type of geological structure is chosen because of their well investigated geological settings and proved sealing capacities, which already enable a present (and future) use as natural (and synthetic) reservoir gas Storages. Nonetheless Hydrogen and hydrocarbon in porous media exhibit major differences in physico-chemical behaviour, essentially due to the high diffusivity and reactivity of Hydrogen. The biotic and abiotic reactions of Hydrogen with rocks and fluids will be necessary observed in siliciclastic sediments which consist of numerous inorganic and organic compounds and comprise original formation fluids. These features strongly control petrophysical behaviour (e.g. porosity, permeability) and therefore fluid (Hydrogen) migration. To reveal the relevance of these interactions and their impact on petrophysics and fluid mechanics in H2STORE six subprojects are included, which are devoted to various aspects of Hydrogen Storage in pore space reservoirs. The analytical and (laboratory) experimental studies will be based on rock and fluid samples issued from different reservoir sandstone and cap rock mudstone types originated from different depths all over Germany. Thereby data on sedimentological, geochemical, mineralogical, hydrochemical, petrophysical and microbiological rock composition will be gained. These studies will be completed with conceptual mathematical and numerical modelling of dynamic reservoir processes, including basin/facies burial evolution, mineralogical alteration, hydro-/geochemical reactions and gas mixing processes coupled with population dynamics of methanogenic microorganisms and dynamic displacement instability effects. The estimation of the Hydrogen impact on reservoir behaviour of different rock types at depths will enable an evaluation of the feasibility of "Eco-/Green" methane and synthetic natural gas (SNG) generation by Hydrogen reaction with CO2. The verification/falsification of specific processes will also enhance predictions on the operational reliability, the ecological tolerance, and the economic efficiency of future energy storing plants. These aspects are main motivations for any industrial investors and the public acceptance of such new technologies within the framework of an overall power supply by renewable energy production.

The H2STORE Project: Hydrogen Underground Storage - A Feasible Way in Storing Electrical Power in Geological Media?
Springer Series in Geomechanics and Geoengineering, 2013Co-Authors: Dieter Pudlo, Viktor Reitenbach, Leonhard Ganzer, Michel Panfilov, Axel Liebscher, Michael Kuhn, Steven Henkel, Marco Lucia, Peter Pilz, Daniel AlbrechtAbstract:The large scale Storage of energy is a great challenge arising from the planned transition from nuclear and CO2-emitting power generation to renewable energy production, by e.g. wind, solar, and biomass in Germany. The most promising option for storing large volumes of excess energy produced by such renewable sources is the usage of Underground porous rock formations as energy reservoirs. Some new technologies are able to convert large amounts of electrical energy into a chemical form, for example into Hydrogen by means of water electrolysis. Porous formations can potentially provide very high Hydrogen Storage capacities. Several methods have to be studied including high Hydrogen diffusivity, the potential reactions of injected Hydrogen, formation fluids, rock composition, and the Storage complex.
