Advances in Green Hydrogen Production, Storage, and Applications

Dear Colleagues,

Green hydrogen has the potential to be a pivotal enabler of the global energy transition, serving as a carbon-neutral fuel and energy carrier for transport, energy storage, and power generation, as well as a feedstock for decarbonising hard-to-abate sectors such as steelmaking. Despite rapid technological progress, key challenges remain in enhancing electrolyser efficiency and durability, reducing production and storage costs, integrating variable renewable energy, and scaling up infrastructure for global deployment.

This Special Issue welcomes original research that advances the full spectrum of green hydrogen production, storage, and applications. We particularly encourage interdisciplinary studies that bridge techno-economic analysis, system modelling, materials science, and policy perspectives to accelerate the sustainable development of the hydrogen economy.

We invite contributions on:

• Production: Innovations in electrolyser technologies (PEM, alkaline, solid oxide), advanced modelling, renewable integration, dynamic operation, cost-reduction strategies, and scalability.
• Storage: Novel materials and systems, including compressed/liquid hydrogen, metal hydrides, chemical carriers (LOHCs), underground storage, and safety protocols.
• Applications: Deployment in ammonia synthesis, steelmaking, heavy transport, power-to-X, grid balancing, and emerging uses in aviation and shipping.

Our goal is to bridge fundamental research with practical implementation, fostering a platform for sharing insights that address technical, economic, and policy challenges. By uniting advances across disciplines, this Special Issue aims to accelerate the role of green hydrogen in achieving global net-zero targets.

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-anonymized 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.
