Special Issue Information

Dear Colleagues,

Developing green energy materials for generation and storage is crucial to advancing sustainable and resilient energy systems. In recent years, the convergence of traditional process modeling and artificial intelligence tools has created new opportunities to design, optimize, and scale these materials more efficiently and with a lower environmental impact.

This Special Issue, "Modeling and Optimization for Green Energy Materials: Machine Learning, Conventional, and Hybrid Approaches", aims to compile research that integrates mechanistic simulation methods, machine learning, and hybrid strategies to study energy materials. Topics of interest include, but are not limited to, the following:

  • Modeling, process simulation, and optimization to produce green energy materials using conventional or hybrid approaches.
  • Applications of machine learning and artificial intelligence in the design, prediction, and control of sustainable materials and processes.
  • The integration of digital tools and application of process simulators and data-driven models to enhance energy efficiency and material performance.
  • Techno-economic, environmental, and life-cycle assessments supported by simulation and intelligent modeling techniques.

We welcome original contributions, both experimental and computational, that advance the state of the art of materials science, process engineering, and data science regarding the energy transition.

We look forward to receiving your contribution and working together to establish a Special Issue with a significant scientific and technological impact.

Sincerely,

Dr. Anibal Alviz-Meza
Prof. Dr. Viatcheslav Kafarov

This study analyzes, quantifies, and maps, from a bibliometric perspective, scientific research on microalgae energy production. It includes traditional simulation, machine learning, and hybrid approaches, covering 500 original articles from 2005 to 2024 in Scopus. We used Biblioshiny 4.1.2 software in RStudio 4.3.0 [...] Read more.
This study analyzes, quantifies, and maps, from a bibliometric perspective, scientific research on microalgae energy production. It includes traditional simulation, machine learning, and hybrid approaches, covering 500 original articles from 2005 to 2024 in Scopus. We used Biblioshiny 4.1.2 software in RStudio 4.3.0 to categorize and evaluate the contributions of authors and journals. The studied field underwent an exponential growth in publications from 2004 to 2022, with an average annual increase of approximately 21%. Moreover, recent research focuses on photobioreactors, computational fluid dynamics, carbon dioxide capture, bio-oils, biodiesel, and hydrothermal liquefaction, increasingly integrating machine learning algorithms and hybrid methods. Since 2020, we have identified a clear trend toward combining modeling approaches to predict and improve energy efficiency, particularly for biodiesel, bio-derived hydrogen, and crude bio-oil produced via pyrolysis or hydrothermal liquefaction, which is often influenced by factors such as light, carbon dioxide, nutrients, and blending operations. Finally, recent advancements involve combining physical models with data to enable real-time optimization and control, supporting microalgae-based circular biorefining strategies. This review serves as a guide for future research in green energy materials and process modeling, inspiring colleagues to explore new ways for microalgae energy production and modeling. Full article
