The course of active development of the Arctic zone of the Russian Federation by companies of the fuel and energy complex implies the development of new methods and approaches to storage and transportation of natural gas in order to reduce the negative impact on the ecosystems of cold regions while maintaining the economic feasibility of its use. This paper proposes a method for optimising the technology of transporting and storing natural gas in the form of gas hydrates using soya lecithin as a promoting additive. Experimental methods show that soya lecithin additive at a concentration of 0.5 wt. % is not inferior to the most effective hydrate formation promoter – sodium dodecyl sulphate at a concentration of 0.1 wt. %. However, a comparison of the environmental characteristics shows a clear advantage for soya lecithin. It is also shown that the synthesis of methane hydrate from ground frozen solutions of soya lecithin is at least three times faster than from liquid solutions.
