The growing interest in the exploitation of marine deposits has resulted in the development of research on deposits and technologies for their exploitation. For several years, the authors have been dealing with one of the most important problems in the deep sea mining of mineral deposits, namely transport from great depths. This publication presents theoretical considerations regarding the use of calcium carbide as a source of energy for transport from the seabed. The authors proposed three lines of the course of the decomposition reaction of calcium carbide and then analyzed the possibility of their use. From the obtained results it can be concluded that the maximum depth of use of a simple CaC 2  distribution is about 1 km, while using the method proposed by the authors based on the “balance of forces” (using an additional medium) it is possible to apply this method to any depth occurring on Earth.
