Heat and Mass Transfer in Energy Conversion and Storage Systems

Dear Colleagues,

Energy conversion and storage systems are pivotal in addressing global energy challenges, with heat and mass transfer playing a central role in their efficiency, performance, and sustainability. This Special Issue, titled “Heat and Mass Transfer in Energy Conversion and Storage Systems”, aims to explore cutting-edge research, innovative methodologies, and practical applications in this field. We invite contributions that advance the understanding of thermal and mass transport phenomena in systems such as lithium-ion batteries, phase-change materials (PCMs), fuel cells, thermal energy storage, and hybrid energy systems. The scope of this issue encompasses experimental, numerical, and theoretical studies focusing on the following topics:

• Enhanced Heat Transfer: Novel materials (e.g., porous media and nanofluids) and techniques (e.g., microchannel cooling and additive manufacturing) for thermal management.
• Mass Transport Optimization: Diffusion, convection, and reactive transport in energy storage devices (e.g., batteries and supercapacitors) and conversion systems (e.g., electrolyzers and solar–thermal systems).
• Phase-Change Phenomena: Solid–liquid and solid–solid transitions in PCMs for thermal storage or regulation.
• Multiphysics Modeling: Coupled thermal–fluid–structural interactions, degradation mechanisms, and lifetime prediction in energy systems.
• Sustainable Applications: Integration of renewable energy sources (wind and solar) with storage technologies, waste heat recovery, and system-level optimization.

This Special Issue seeks to bridge fundamental research with industrial applications, highlighting innovations that improve energy density, efficiency, and scalability.

Submissions addressing challenges such as thermal runaway mitigation, interfacial transport, or system-level integration are particularly encouraged.

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. 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.
