Special Issue Information

Dear Colleagues,

It is difficult to envision an energy future without a comprehensive understanding of the economic viability and environmental impacts of emerging energy carriers and systems. As global efforts intensify to reduce emissions for sectors such as transportation, aviation, and industry, a wide range of solutions are being actively developed and deployed, including bio-derived fuels, hydrogen, synthetic fuels, electrified systems, and hybrid energy pathways.

This Special Issue aims to integrate the techno-economic analysis (TEA) and life cycle assessment (LCA) of energy carriers and systems to support the global transition toward low-emission and cost-effective energy solutions.

Topics of interest for publication include, but are not limited to:

  • TEA and/or LCA analysis on energy carriers and systems;
  • Alternative energy carriers, such as bio-derived fuels, hydrogen, and synthetic fuels;
  • System-level evaluation of energy pathways from resource extraction to plant-gate or end-use;
  • Cost, emissions, and performance trade-offs across energy technologies;
  • Supply chain design, optimization, and resilience for energy systems;
  • Integration of renewable energy with existing energy systems;
  • Simulation of energy systems under varying market, policy, and operational conditions;
  • Data-driven and AI-enabled approaches for TEA and LCA;
  • Comparative assessment of energy carriers across sectors (transportation, aviation, or industry);
  • Policy, regulatory, and market implications for the deployment of energy technologies.

Woody biomass is often promoted as a low-carbon energy source in global decarbonization efforts. However, LCA (life cycle assessment) evaluations of woody biomass-to-energy systems show very different environmental performance. Variations in technology and methodology across investigations can cause these inconsistencies. This review paper analyzes methodologies of LCAs of woody biomass conversion routes such as combustion, combined heat and power, gasification, pyrolysis, torrefaction-assisted systems, and new bioenergy with carbon capture configurations. A systematic literature review was conducted using Scopus, SpringerLink, and ScienceDirect, identifying 4272 records, of which 98 studies were retained for detailed analysis following the application of defined inclusion and exclusion criteria. Functional unit selection, from biomass mass per unit to power or heat per unit, is highly variable, affecting comparability. Forest carbon stock fluctuations, infrastructure, and end-of-life treatment are inconsistently included in cradle-to-grave system boundaries. Static GWP100 methods are often used in biogenic carbon removal without considering temporal carbon dynamics. The importance of pretreatment steps like drying, pelletizing, and torrefaction cannot be overstated, even though they have a direct impact on the quality of the fuel, the efficiency of transportation, and the effectiveness of the conversion process downstream. The large range of stated emission levels for comparable technologies is further influenced by logistics assumptions, plant scale, and allocation mechanisms in cogeneration systems. The review synthesizes these methodological differences and proposes a harmonization methodology to increase woody biomass LCA transparency and comparability. By identifying important sources of outcome variability, this study helps policymakers, project developers, and industry stakeholders evaluate biomass energy investments and bring clarity to environmental decisions.

This integrative critical review examines how biomass and bioenergy can contribute to energy diversification while accounting for constraints related to climate mitigation, energy security, resource availability, and technology readiness. The review combines a targeted literature synthesis with expert-informed insights from the international seminar Energy Transition and Biofuels held at the Federal University of Itajubá in October 2025. The seminar and COP30-related discussions were used as contextual and conceptual inputs, while peer-reviewed literature, policy documents, and technical reports provided the evidentiary basis for the analysis. The manuscript evaluates biomass and biofuels utilization, refinery integration, sustainable aviation fuels, biochar, BECCS, hydrogen synergies, life-cycle assessment, artificial intelligence, and logistics. The synthesis indicates that biomass is not a universal substitute for fossil fuels. Still, it has distinctive value in applications requiring renewable carbon, dispatchable energy, process heat, liquid fuels, carbon removal, and compatibility with existing infrastructure. The analysis also shows that these contributions are contingent on feedstock governance, land and water safeguards, logistics, fertilizer inputs, technology maturity, and verified life-cycle performance. The food–fuel discussion is therefore reframed as a context-specific problem of land-use, access, productivity, and governance rather than a simple competition between energy and food production. The study concludes that bioenergy can most credibly support the energy transition when deployed through differentiated pathways tailored to regional resources, sustainability constraints, and sector-specific decarbonization requirements.
