The article reveals the potential and ecological importance of using liquefied hydrogen on civil fleet vessels as
fuel. The current requirements for the content of hazardous substances in exhaust gases, characteristics of the
average energy complex of a civil fleet vessel are considered. The calculation of the required amount of liquefied
hydrogen to provide a certain power capable of powering a number of ship consumers has been made. The
calculation of the amount of liquefied hydrogen that can be obtained by using a sectional filter with a graphene
membrane and a cryogenerator has been made. The conclusion is made about the high efficiency of hydrogen
storage batteries that receive hydrogen from the exhaust gases of a ship's power plant
In the modern world, the problem of environmental pollution with various toxic emissions is growing more and
more. Exhaust or exhaust gases of internal combustion engines are one of those man-made factors. All countries
impose restrictions on the concentration of hazardous substances, for example: Euro - for cars, Tier and Stage
- for heavy equipment and MARPOL-73/78, which regulates emissions from maritime transport. The situation
is extremely acute for marine vessels, since engines of impressive power that operate for a long period are
difficult to adapt to stringent environmental requirements. The purpose of the article, based on open sources, is
to evaluate the prospects for the development of internal combustion engines with an exhaust gas recirculation
system to minimize the amount of toxic emissions into the atmosphere. The development of technologies that allow for the recirculation of exhaust gases in ship conditions is quite promising. The installation of such equipment
will significantly reduce emissions into the environment.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
