Summary: Ammonia is a promising carbon-free alternative fuel for reducing carbon emissions in marine engines. The study found that ammonia-diesel stratified injection technology can significantly reduce CO2 and NOx emissions, improve energy ratio, and meet future low-carbon emission regulations without the need for after-treatment. Increasing injection pressure and reducing pilot fuel proportion is the optimal solution for achieving high IMEP, low NOx, and carbon emissions.

Summary: This paper presents a new design of marine engines that replace two-stroke internal combustion engines with a combination of gas Brayton cycle, solid oxide fuel cell, and two organic Rankine cycles. Sustainable fuels such as hydrogen, methane, dimethyl ether, ethanol, and methanol are used, along with liquified natural gas for cooling processes. The thermodynamic analysis shows that the integrated hybridized marine engine has improved performance with a total power boost of 33% and average energetic and exergetic efficiencies of 38% and 46% respectively. The proposed engine achieves maximum power with sustainable fuel blends, resulting in an 83% reduction in carbon emissions and minimum specific fuel consumption.

Summary: Any equipment submerged in the ocean will be attacked by fouling organisms, causing serious damage. Traditional antifouling coatings with heavy metal ions have negative effects on the marine environment and are not practical. With increasing environmental awareness, new environmentally friendly and broad-spectrum antifouling coatings have become a hot topic in marine antifouling research. This review outlines the formation process and mechanism of biofouling, and describes recent research progress in new environmentally friendly antifouling coatings, including fouling release coatings, photocatalytic coatings, biomimetic antifouling agents, micro/nanostructured materials, and hydrogel coatings. Future research directions are also discussed to guide the development of efficient and green marine antifouling coatings.

Summary: The global issue for countries currently is the search for raw materials and the production of bioenergy, such as biodiesel fuels. Promising biodiesel fuels include green diesel fuel produced from hydrogenation of vegetable oils. Three methods have been proposed to obtain high-quality and environmentally friendly diesel fuel: compounding green diesel with hydro-treated diesel fuel, compositions of improved fuel with bio-additives, and two-component mixtures of environmentally friendly diesel fuel with bio-additives. These methods can produce fuel for diesel engines with improved lubricating properties and reduced wear scar diameter.
