The emissions problem caused by rapid maritime trade development cannot be overlooked, as the toxic substances in ship exhaust are harmful to the environment and human health. To mitigate these adverse effects and comply with stricter emission regulations, the shipping industry is advised to adopt new clean energy sources and efficient exhaust control technologies. This paper reviews the impact of ship emissions on the environment and health, new regulations, clean energy application, and exhaust gas after-treatment technologies.
Ship emissions problems caused by the rapid development of maritime trade can't be ignored. The NOX, SOX, CO2, PM and other toxic substances contained in the exhaust gas are extremely harmful to the environment and human health. In order to cope with the adverse effects of ship emissions and the increasingly stringent emission regulations formulated by the IMO and governments, the shipping industry needs to adopt new clean energy and high-efficiency exhaust control technologies to reduce ship emissions. This paper provides a comprehensive review, including: (1) The impact of pollutants such as NOX, SOX, CO2 and PM emitted by ships on the environment and human health; (2) New regulations about ship exhaust emissions; (3) Application of clean energy such as LNG, biodiesel, methanol, hydrogen and ammonia on ships; (4) After-treatment technology of ship exhaust gas such as SCR and EGR. And focusing on the principles, uses, characteristics, implementation obstacles and prospects of different energy and technologies, with a view to provide some help for the research on ship exhaust emissions control.
