Commercialization of Construction and Operation Stages of Large-Scale Underground Accumulators of Gas and Liquid Energy Carriers

The article describes the relevant issues associated with the reduction of capex and opex of large-scale underground accumulators of gas and liquid energy carriers by commercializing the stages of their construction and operation. It is shown that during the construction of underground storage, the generated construction brine, which is a waste product, can be a raw material for the creation of products of high consumer value for the country’s economy. Technological schemes for the production of economically useful products in cooperation with the process of constructing underground storage in rock salt deposits and the operation of an underground accumulator of natural gas are presented. All the technological schemes are developed based on highly efficient production of common and technical salt, calcined soda, chlorine, glass, hydrogen (methane-hydrogen mixture), ammonia, carbamide. It is shown that the implementation of the developed schemes of cooperation of technological complexes for the production of essential and useful for the country’s economy products significantly reduces total capital and operational costs and, consequently, the cost of the output product.
