In various systems of aerospace engineering, transport, as well as in energy complexes for various purposes, cryogenic liquids are now widely used. Liquefied natural gas (LNG) is an environmentally friendly energy source that has several advantages over petroleum products. LNG using reduces the weight and size characteristics of tanks for storage and transportation. Reducing the loss of cryoproducts using low-potential power machines to ensure efficient storage of cryoproducts. Significant problems associated with the loss of its low-potential energy (caused by heat from the environment). There is a need to improve solutions to compensate for losses and expenses. This study examined the possibility of reducing the loss of cryoproducts when stored in tanks and transportation systems. Details were studied: assessment of losses of the cryoproduct and its capabilities for low-temperature energy, calculation of the loss compensation loop, calculation of the contour for generating additional energy based on a heat power plant, analysis of low-potential power plants, compensating losses of cryoproducts during storage. The main results of the research are the proposal to organize the LNG Storage, calculate the loss compensation loop and the supplementary energy circuit.

The use of LNG for the production of additional energy is topical today. Very often LNG is used for gasification of settlements and industrial enterprises. LNG makes it possible to gasify objects remote from main pipelines for long distances by creating an LNG reserve directly from the consumer, avoiding the construction of expensive piping systems. However, in this case, there are large losses of cryoproduct and its low-potential heat. In this article, we propose a technical solution for compensating for the loss of cryoproducts during storage using an installation consisting of two circuits, one of which is a loss compensation loop and the other is a circuit for generating additional energy. The conducted researches showed that the use of this system allowed to return the previously used for liquefying electric power in the amount of 24%.
