Special Issue Information
Dear Colleagues,
Sustainable fuels are derived from renewable materials rather than fossil fuels and include biofuels like ethanol, green gasoline, and hydrogen-based fuels.
While fossil fuels have been crucial for modern life, their use contributes significantly to environmental depletion. Sustainable fuels represent a potential solution; indeed, they could reduce greenhouse gas emissions by up to 90% if deployed at scale. For instance, certified sustainable aviation fuels (SAFs) emit about 80% less greenhouse gas than traditional jet fuel.
Sustainable fuels can be categorised into three types:
- Conventional biomass-based fuels, made from organic matter, such as first- and second-generation ethanol, biodiesel (FAME), and biogas from waste;
- Drop-in fuels, which can replace fossil fuels in existing engines and are produced from various biomass sources using low-carbon hydrogen;
- Non-drop-in e-fuels, produced by using captured carbon and hydrogen from renewable energy, including e-methanol and e-ammonia.
Despite some sustainable fuel industries still being in their infancy, demand is expected to quadruple by 2050, potentially accounting for up to 37% of energy used in transportation.
However, sustainable fuel production must be balanced with food needs, necessitating a careful approach to sourcing feedstocks. Lastly, regulation will be key in shaping future sustainable fuel demand.

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. Inventions 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 1800 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.
