Special Issue Information
Dear Colleagues,
The intermittent nature of renewable energy sources (RES), as non-dispatchable power generation units, has resulted in the need for sophisticated energy storage systems. Power-to-Hydrogen (PtH), which involves converting renewable energy surpluses into fuel, storage, and reconversion back to electricity, is a promising pathway to the decarbonization objective. Nevertheless, the interaction between the power grid, electrolyzers, hydrogen storage system, and RES creates a complex system with operational asymmetries. The electrolyzer, fuel cell efficiency, and the hydrogen pressure asymmetry have an impact on the symmetry of the hydrogen conversion system. Additionally, the value chain for renewable hydrogen may also represent economic asymmetries. Moreover, power electronic converters based on RES may create harmonics and other distortions that affect the symmetry of voltage and current waveforms as well as the instability of voltage and frequency. Therefore, understanding and addressing these operational asymmetries is crucial for the successful integration of hydrogen into a renewable energy system, ensuring a reliable, sustainable, and cost-effective energy future.
This Special Issue aims to highlight both theoretical and applied advances in RES-based hydrogen conversion systems by addressing optimal, advanced, and resilient control strategies for enhancing the efficiency and durability of electrolyzers and fuel cells and optimizing the integration of hydrogen systems with RES.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
