New Publication in MDPI's Energies Journal: Advancing Renewable Energy Optimization
We are proud to introduce the latest publication in MPI’s “Energies” journal, an open access journal on scientific research, technology development, engineering policy, and management studies related to the general field of energy.
The paper “Wind-Photovoltaic-Electrolyzer-Underground Hydrogen Storage System for Cost-Effective Seasonal Energy Storage” was written by our VTU colleagues Process Engineer Martin Hunyadi-Gall and Senior Process Engineer Andreas Lunzer, together with Torsten Clemens, Vladislav Arekhov, Martin Datler, and Albert Gauer from the Austrian multinational integrated oil, gas and petrochemical company OMV.
About the content:
Solar (PV) and wind energy systems can power the grid or produce hydrogen, which can be stored underground for use during times of high demand. However, designing these systems is challenging due to the interactions between components.
To address these challenges, process modelling was applied using cost components and parameters from a project in Austria. The hydrogen storage part was derived from an Austrian hydrocarbon gas field considered for UHS. The results highlight the impact of the renewable energy source (RES) sizing relative to the electrolyzer capacity, the influence of different wind-to-PV ratios, and the benefits of selling electricity and hydrogen.
Overall, the analysis demonstrates the feasibility of integrated RES–hydrogen generation-seasonal energy storage projects in regions like Austria, with systems that can be dynamically adjusted to market conditions.
