Special Issue Information

Dear Colleagues,

The issue and tasks of decarbonizing the maritime sector are inseparably linked to the global strategic goals of achieving climate neutrality, becoming the foundation for the advancement of smart ships and the development of maritime port infrastructure technologies. The problem of decarbonization is just as relevant for the maritime sector as it is for land transport, which is a major air pollutant. In the future, the environmental impact from ships will increase due to the increase in the global fleet and the associated consumption almost exclusively of fossil fuels. In this regard, the International Maritime Organization adopted amendments to MARPOL 73/78, which introduced the CO2 emission limitation indicator, the Energy Efficiency Design Index (EEDI), since 2023 m. January 01 Energy Efficiency eXisting ship Index (EEXI), and carbon intensity indicator (CII), which also serves as an indicator of a ship's energy efficiency. The regulated improvement in the short-term EEDI 20-30% allows for the implementation of a wide range of innovative technologies, which provide a reduction in the resistance to movement, cogeneration and trigeneration of secondary heat sources, effective use of unconventional and alternative fuels (including natural gas, synthetic alcohols, hydrogen, ammonium, etc.), improvement propulsion of ship by sources of alternative energy such as wind power (Magnus effect, for instance), solar power, etc. Achievement of a synergistic effect from the application of innovations provides a systematic approach of multilevel parametric optimization of the indicators of systems and power plants of the ship.

Ports are also a crucial link in improving shipping technologies to enhance environmental indicators and generally reduce the carbon dioxide emissions in the maritime sector towards sustainable development. Measures outlined in the "Fit for 55 package" foresee the implementation of such a comprehensive approach. Primarily, this includes transitioning energy facilities to renewable and low-carbon (RLC) options, reducing greenhouse gas emissions throughout the supply chain, developing and enhancing RLC and LNG bunkering port infrastructure, supplying electricity from shore to main EU TEN-T maritime ports, expanding the emissions trading system to the maritime sector, controlling energy consumption efficiency, and digitizing port management systems, among other initiatives.

This Special Issue is focused on a broad presentation of the results of scientific research, technological design, and regulatory decisions related to the above-mentioned aspects of the problem.

The results of scientific research and statistical data largely indicate a successful resolution of the decarbonization issue in the maritime sector, allowing for potential authors to publish articles in a Special Issue and to garner reader interest.

Abstract
The International Maritime Organization (IMO) has set targets to reduce carbon emissions from shipping by 40% by 2030 (IMO2030) and 70% by 2040 (IMO2050).

The International Maritime Organization (IMO) has set targets to reduce carbon emissions from shipping by 40% by 2030 (IMO2030) and 70% by 2040 (IMO2050). Within the framework of decarbonising the shipping industry, liquefied natural gas (LNG) fuel and carbon capture technologies are envisioned as a transitional option toward a pathway for clean energy fuels. The aim of the complex experimental and computational studies performed was to evaluate the CO2 capture potential through the utilisation of LNG cold potential on the FSR-type vessel within a dual-fuel propulsion system. Based on the experimental studies focused on actual FSRU-type vessel performance, the energy efficiency indicators of the heat exchanging machinery were determined to fluctuate at a 0.78–0.99 ratio. The data obtained were used to perform an algorithm-based systematic comparison of energy balances between LNG regasification and fuel combustion cycles on an FSRU-type vessel. In the due course of research, it was determined that LNG fuel combustion requires 18,254 kJ/kg energy to separate and capture CO2 in the liquid phase to form exhaust gas; meanwhile, low sulfur marine diesel oil (LSMDO) requires 13,889 kJ/kg of energy. According to the performed calculations, the regasification of 1 kg LNG requires 1018 kJ/kg energy, achieving a cryogenic carbon capture ratio of 5–6% using LNG as a fuel and 7–8% using LSMDO as a fuel. The field of carbon capture in the maritime industry is currently in its pioneering stage, and the results achieved through research establish an informative foundation that is crucial for the constructive development and practical implementation of cryogenic carbon capture technology on dual-fuel ships.
