Alternative Fuels for Marine, Aviation and Vehicle Transportation Sectors: Production, Propulsion and Power Generation Technologies

Dear Colleagues,

We would herewith like to welcome submissions to a Special Issue of Energies on the subject area of “Alternative Fuels for Marine, Aviation and Vehicle Transportation Sectors: Production, Propulsion and Power Generation Technologies”. The “Green Deal” and other environmental awareness initiatives that have been undertaken in the international fora of the marine, aviation and vehicle transportation sectors have focused on the production and utilization of alternative gaseous and liquid fuels, such as ammonia, hydrogen, natural gas, LPG and alcohols, because these fuels have the capacity to significantly reduce the operational carbon footprint of the transportation means in the previously mentioned transportation sectors. When the production of alternative fuels is based on the use of alternative energy sources, such as wind energy or solar energy, then the alternative fuels are called “green fuels”, and in this case, not only their operational carbon footprint but also their life-cycle carbon footprint is significantly lower compared to the corresponding life-cycle carbon footprint of conventional production methods used to produce alternative fuels. The most significant challenge of green and alternative fuels production is that most of the methods presented in the literature indicate high energy consumption rates, and they are not cost-effective. Hence, it is of the utmost importance nowadays and in the years to come to develop methods and technologies that reduce the energy consumption and the production cost of carbon-neutral alternative fuels to make them economically competitive with conventional liquid and gaseous fuels, thus strengthening the degree of penetration of alternative fuels in the marine, aviation and vehicle transportation sectors. On the other hand, the use of alternative fuels in marine, aviation and vehicle propulsion systems can significantly improve the environmental footprint of these propulsion systems; however, it is usually accompanied by serious technical, economic and environmental challenges, which should be confronted to develop economically viable and carbon-free contemporary marine, aviation and vehicle propulsion systems. For this reason, as Guest Editors, we kindly invite submissions relevant to production technologies of alternative fuels, either as green fuels or blue fuels or grey fuels, combustion of alternative fuels in internal combustion engines, gas turbines, steam turbines and combined cycles, electrochemistry power generation and propulsion systems utilizing alternative fuels, such as fuel cells with hydrogen carriers, on-board storage and distribution of alternative fuels and alternative fuels’ supply to propulsion systems.

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-anonymized 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.
