Sustainable Biofuels for Carbon Neutrality: Progress, Challenges, and Prospects

Dear Colleagues,

Sustainable biofuels play a major role in climate mitigation since they can lower net emissions across sectors that struggle to electrify. This Special Issue invites studies that show how advanced biofuels contribute to carbon neutrality through measurable gains in conversion efficiency, improved feedstock use, and realistic deployment pathways. We welcome research that links process engineering with system analysis, policy, and supply chain design. The scope covers biochemical and thermochemical routes, waste-based feedstocks, algal systems, fuel quality, integration with existing energy infrastructure, and the life cycle of greenhouse gas emissions. We also seek papers that test economic feasibility, quantify environmental trade-offs, and assess social impacts in regions with different resource conditions. Submissions may rely on laboratory experiments, pilot-scale trials, modelling, or comparative assessments. Review papers with a clear research question are encouraged. The goal is to identify gaps that limit the wide deployment of sustainable fuels.

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

• Sustainable biofuels for carbon neutrality;
• Advanced conversion pathways in biofuel production;
• Low-carbon supply chains for biomass;
• Waste- and residue-based feedstocks;
• Algal and microbial fuel systems;
• Thermochemical routes for renewable fuels;
• Biochemical routes and enzyme-based processes;
• Greenhouse gas accounting across the fuel life cycle;
• Integration of biofuels in the aviation and maritime sectors;
• Regional resource potential and deployment scenarios;
• Techno-economic evaluation of biofuel processes;
• Environmental and social impacts of biofuel expansion;
• Policy frameworks that support sustainable fuel markets.

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-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.
