“…The mineral sequestration of CO 2 using FBC fly ashes from hard coal is a particularly interesting option for southern Poland, where the potential for geological storage is limited 20 . FBC fly ashes from hard coal combustion have been used in Poland for many years, mainly in mining, construction materials, and road construction 4 .…”

The production of electricity and heat in Poland is the reason why the commercial power industry is the largest emitter of CO 2. At the same time, significant amounts of solid by-products of combustion, which can be used to bind CO 2 by mineral carbonation, are generated during the production processes. The article presents the results of research on mineral sequestration of CO 2 (suspension-CO 2) using fluidized bed combustion (FBC) fly ashes from hard coal combustion. The analyzed fluidized bed combustion (FBC) fly ashes were characterized by a significant free CaO content (1.7-6.8%) and a high co 2 binding potential ranging from 9.7 to 15.7%. In the case of fluidized bed combustion (FBC) fly ashes suspensions, the basic product of the carbonation process is calcium carbonate, which is clearly indicated by the results of the phase composition determination of solidified suspensions of fluidized bed combustion (FBC) fly ashes. The degree of carbonation, i.e. the degree of CO 2 binding, calculated on the basis of the calcium carbonate content, in the analyzed suspensions was up to 1.1%. Mineral carbonation also reduces the leachability of pollutants such as: Zn, Cu, Pb, Ni, As, Hg, Cd, Cr, Cl, and SO 4 2-. The pH is also reduced from about 12 to about 9. Aqueous suspensions of fluidized bed combustion (FBC) fly ashes with introduced CO 2 can potentially be used in underground mining. These activities are in line with the concepts of Carbon Capture and Utilization and the idea of circular economy.

“…In addition, rock formations provide natural protection (including mechanical and thermal protection) against the effects of the external environment. An important feature of underground facilities, which affects the safety of their use, is that the access points to these facilities are small and easily secured [1]. The rock mass is used for various purposes.…”

Energy, gases, and solids in underground sites are stored in mining excavations, natural caverns, salt caverns, and in the pore spaces of rock formations. Aquifer formations are mainly isolated aquifers with significant spreading, permeability, and thickness, possessing highly mineralized non-potable waters. This study discusses the most important aspects that determine the storage of natural gas, hydrogen, or carbon dioxide in deep aquifers. In particular, the selection and characterization of the structure chosen for underground storage, the storage capacity, and the safety of the process are considered. The choice of underground sites is made on the basis of the following factors and criteria: geological, technical, economic, environmental, social, political, or administrative–legal. The geological and dynamic model of the storage site is then drawn based on the characteristics of the structure. Another important factor in choosing a structure for the storage of natural gas, hydrogen, or carbon dioxide is its capacity. In addition to the type and dimensions of the structure and the petrophysical parameters of the reservoir rock, the storage capacity is influenced by the properties of the stored gases and the operating parameters of the storage facility. Underground gas storage is a process fraught with natural and technical hazards. Therefore, the geological integrity of the structure under consideration should be documented and verified. This article also presents an analysis of the location and the basic parameters of gas storage and carbon dioxide storage facilities currently operating in underground aquifers. To date, there have been no successful attempts to store hydrogen under analogous conditions. This is mainly due to the parameters of this gas, which are associated with high requirements for its storage.

In the shallow frozen soil in severe cold areas, the overall thermal performance of the structure is very important for the creation of the internal thermal environment. In this paper, CFD simulation calculation software is used to analyze the internal temperature field distribution of the shallow buried underground space with ordinary thermal insulation structure using only polyurethane and three improved thermal insulation structures with rock wool, polystyrene board and aerogel added. The results show that the three improved thermal insulation structures have an average increase of 9°C, 10.5°C and 12.5°C in indoor temperature compared with ordinary thermal insulation structures. Among them, thermal insulation materials in the form of polyurethane + air + aerogel have the most obvious improvement to the indoor environment.
