Smart Air-Cleaning Technologies for Next-Generation Energy Systems

Dear Colleagues,

The rapid evolution of clean and efficient energy systems requires advanced methods for particulate and gas emission control. Electrostatic precipitators (ESPs), traditionally used in large-scale power and industrial applications, are now being reimagined through hybrid designs with plasma-assisted technologies and intelligent control systems.

ESPs remain some of the most energy-efficient technologies for emissions reduction in industrial and energy systems. However, the recent use of plasma reactors, catalytic surfaces, advanced electronics, and intelligent control has opened new research directions with strong environmental, industrial, and domestic potential.

This Special Issue aims to highlight recent advances, models, and applications of modern filtration technologies across diverse energy platforms, from wood, biomass, and waste to smart air-cleaning technologies.

This Special Issue welcomes contributions with focuses including, but not limited to, the following:

-Design optimization and new materials for high-efficiency filters;

-Filtration systems for particulate and gas removal;

-Filtration applications in biomass-, pellet-, and wood-based energy systems;

-Numerical modelling of electric fields and particulate dynamics;

-Intelligent control, optimization, and automation in filtration operation;

-Experimental studies on PM, NO_x, hydrocarbons, SO₂, and VOC reduction;

-Miniaturized and hybrid filtration for domestic and transport applications;

-Plasma-assisted oxidation and electro-catalytic emission control;

-Integration of cleaning technologies in circular energy and energy recovery systems.

This Special Issue aligns with the mission of Energies to promote sustainable, interdisciplinary approaches for energy conversion and pollution control. It will provide a platform for engineers and researchers, and technologists to share recent results and stimulate international collaboration in this rapidly developing field.

We invite original research articles, reviews, and case studies focusing on the integration of electrostatic, plasma, catalytic, and intelligent systems for environmental and energy applications.

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.
