Scientific Advances and Challenges in Ship Waste Heat Utilization

Dear Colleagues,

Marine transportation plays a very important role in the trade transportation of all countries. According to statistics, the cargo carried by ships accounts for more than 80 percent of the global trade volume. However, ships that consume fossil fuels emit large quantities of greenhouse gases. The main fuel-consuming devices are the main engine, auxiliary engine and auxiliary boiler. Among them, the consumption of the main engine is the largest, accounting for about 70%~90%. According to literature statistics, the comprehensive energy utilization rate of modern marine diesel engines can only reach half of the energy, and the other half of the energy is discharged into the external environment in different forms of waste heat. Finding ways to harness this energy could greatly improve ship efficiency and reduce greenhouse gas emissions. Ship waste heat utilization technology covers many interdisciplinary disciplines, such as engineering thermophysics, materials, chemistry, etc., and requires in-depth academic and technical exchanges between experts and scholars in different fields. Therefore, Applied Sciences plans to organize this Special Issue entitled "Scientific Advances and Challenges in Ship Waste Heat Utilization" to explore the scientific frontier and ongoing challenges of ships’ waste heat utilization. The key topics of interest include (but are not limited to):

• Ship waste heat utilization;
• Ship waste heat power generation;
• Ship waste heat refrigeration;
• Ship waste heat heating;
• Ship waste heat desalination;
• Ship waste heat storage;
• Ship waste heat deep utilization;
• Ship waste heat utilization at ultra-low temperatures.

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. Applied Sciences 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 2400 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.
