On the Possibility of Using Carbon Dioxide as an energy Carrier for Transport from the Seabed

Abstract

Achieving the 50% reduction in CO 2 emissions set by the European Union by 2050 is impossible without developing technologies for capturing carbon dioxide and its safe storage. As our everyday lives are increasingly influenced by public, scientific and political debates on global warming (from extreme weather phenomena to melting glaciers), which often result in legal regulations, appropriate technologies should be developed to eliminate the causes of these phenomena. Therefore, reducing anthropogenic carbon dioxide emissions, which have a significant impact on the greenhouse effect, is one of the most important problems to be solved in the field of broadly understood environmental protection (Mazurkiewicz et al., 2005). The seas and oceans, covering approximately 70% of the globe's surface, play a key role in the absorption of anthropogenic CO 2 emissions into the atmosphere. For several years, the authors have been conducting research related to the transport of excavated material from great depths and have presented several concepts (Filipek W., Broda K.: 2016, 2017, 2018, 2019, 2023). In this article, the authors, following the global trend regarding the management of CO 2 of anthropogenic origin, attempted to use it as a working medium for transport from the seabed. In their considerations, the authors focused mainly on the usable energy stored in the analyzed working medium. The authors are aware of the negative effects of carbon dioxide on the marine environment. Nevertheless, we found it necessary, taking into account future research on the use of this working medium, to first consider the so-called open system, i.e. free exchange of CO 2 between the transport module and the surroundings. From our point of view, this is important information that is a reference point for future concepts of using this medium in the so-called closed system, i.e. assuming that there is no transmission of CO 2 to the marine environment.
