Special Issue Information
Dear Colleagues,
We are inviting submissions to the Energies Special Issue on ‘Advances in Green Hydrogen Production Technologies’.
The durability of green hydrogen production technologies is one of the most significant challenges for their wider commercialization. For instance, the fluctuating intensity of input electricity derived from renewable energy sources, utilized in the electrolysis process for producing green hydrogen, leads to variations in operating temperatures. Consequently, the maintenance of these temperatures becomes necessary, posing both operational challenges and safety risks—operation at very low input currents can cause the mixing of hydrogen and oxygen, while frequent switching the device on/off, as well as operation with variable currents and temperature, affect the durability of the device. Therefore, a deeper understanding of their processes and complex mechanisms of performance degradation during operation is still a hot research topic and indispensable requirement in practice, alongside a need for the advanced in situ diagnostics of the phenomenon itself and monitoring of its progression. This is especially crucial for identifying the cause(s) of performance degradation. The ultimate broader aim is collecting more comprehensive information on the current state of performance of these devices for more efficient (green) hydrogen production, as well as forecasting their remaining useful lifetime. On the other hand, the wide range of procedures for accelerated degradation testing makes it difficult to compare the obtained results. Hence, due to the presence of non-linearity and even pronounced data stochasticity, their practical application in further analysis and interpretation is often very inappropriate. Moreover, the biggest challenge is still to extract useful information from such a large set of measured data, especially during the operation of these devices in practice.
Therefore, further progress and the realization of the expected scientific contributions of novel and original scientific papers on this very attractive topic should certainly represent a great challenge and motivation for researchers in this field.

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 250 words) can be sent to the Editorial Office for assessment.
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. Energies is an international peer-reviewed open access semimonthly 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 2600 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.
