Special Issue Information
Dear Colleagues,
Rising global energy demand coupled with the consequences of carbon emissions, especially from the transport sector, requires alternatives, such as biofuels. Microalgal biofuel could be a promising alternative, as microalgal biomass can be produced using seawater or wastewater, which improves the sustainability and economics of algal biofuel without competing for arable lands and freshwater for food crops. Since the biomass productivity of specific microalgae can exceed those of any other terrestrial plants, microalgal biofuel production can also be used as enhanced Carbon Capture and Utilization (CCU). Advances in microalgal biotechnology are improving feedstock yields while reducing biomass production costs. Similarly, there are ongoing efforts to reduce the energy and cost of various unit operations in the downstream feedstock processing to biofuels. Investing in microalgae could be crucial for transitioning to a low-carbon future while addressing key environmental and economic challenges.
This Special Issue welcomes all the recent advances in microalgal biofuel, including but not limited to the feedstock conversion processes to various fuels, environmental sustainability, and the economic viability of algal biofuel:
- Microalgal biomass production for biofuel applications;
- Hydrothermal Liquefaction (HTL) of algal biomass;
- Sustainable Aviation Fuel (SAF) from microalgal biomass;
- Biodiesel from algal feedstock;
- Pyrolysis of algal biomass;
- Anaerobic digestion of algal biomass;
- The application of Artificial Intelligence (AI) in algal biofuel;
- Biorefinery pathways for algal biofuel;
- Life Cycle Analysis (LCA) and Techno-economic Analysis (TEA) of microalgal biofuel.

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.
