“…32–34 However, usually these scientific works did not consider the UGS role for optimizing the network planning and operation, in their modeling exercise from the start. For instance, Petrovich and Rogers 35 modeled natural networks and aimed to find bottlenecks, but did not consider applying UGS to solve these bottlenecks, while Szoplik and Stelmasinska 36 modeled a network in Poland considering LNG storage and biogas supply, but simply not indicating the UGS option. In South America, Chávez-Rodríguez et al 37 used TIMES tool to develop a simplified natural gas network model for the Southern Cone countries but did not focused on UGS.…”

Some emerging countries, such as Brazil, have large remaining natural gas resources but relatively poor infrastructure to monetize it. When most of the natural gas extraction derives from associated gas, this results in high reinjection rates in production fields combined with fuel imports also to deal with an increasingly variable demand. This study test the hypothesis that modeling the natural gas transportation network expansion with Underground gas Storage (UGS) is crucial, as UGS can reduce transportation costs by better fitting natural gas supply and demand. Without UGS chances are that network expansion will be based in oversized pipelines, or pipelines often challenged by peaking demands. Therefore, this study emulated a real natural gas transport network in a thermo-hydraulic model, aiming at diagnosing its bottlenecks mainly caused by demand intermittency, and pointing out infrastructure solutions. Findings indicated the design of UGS associated with new pipelines as a problem-solver for network bottlenecks, under a least-cost approach. This option reduced idleness and lowered gas transmission costs by 60%. In addition, it increased the network operation reliability and created a virtuous cycle, where a better planning reduces the gas tariffs and spur infrastructure expansion by raising the fuel competitiveness.

“…Regarding Russian gas, methane accounted for approximately 97% and ethane for 1%. In contrast, for LNG, the rate of methane is generally lower, typically below 95%, with ethane ranging from 2% (Egypt), to approximately 6% (Norway, Nigeria, Qatar) and up to 13% (Libya) [19][20][21][22]. The growing use of LNG to meet domestic gas demand has an impact on the levels of methane and ethane present in natural gas, as seen in Figure 3.…”

Thanks to investments in diversifying the supply of natural gas, Poland did not encounter any gas supply issues in 2022 when gas imports from Russia were ceased due to the Russian Federation’s armed intervention in Ukraine. Over the past few years, the supply of gas from routes other than the eastern route has substantially grown, particularly the supplies of liquefied natural gas (LNG) via the LNG terminal in Świnoujście. The growing proportion of LNG in Poland’s gas supply leads to a rise in ethane levels in natural gas, as verified by the review of data taken at a specific location within the gas system over the years 2015, 2020, and 2022. Using measurements of natural gas composition, the effectiveness of the steam hydrocarbon reforming process was simulated in the Gibbs reactor via Aspen HYSYS. The simulations confirmed that as the concentration of ethane in the natural gas increased, the amount of hydrogen produced, and the heat required for reactions in the reformer also increased. This article aims to analyze the influence of the changes in natural gas quality in the Polish transmission network caused by changes in supply structures on the mass and heat balance of the theoretical steam reforming reactor. Nowadays, the chemical composition of natural gas may be significantly different from that assumed years ago at the plant’s design stage. The consequence of such a situation may be difficulties in operating, especially when controlling the quantity of incoming natural gas to the reactor based on volumetric flow without considering changes in chemical composition.

“…Another major research topic is about the modelling of the gas grid to simulate its operation with different percentages in volume of hydrogen, and to optimize its interaction with other systems such as the electric grid. Many models are utilized to simulate the grid as an isolated system, to explore the capabilities of the grid to work with various blends of methane/hydrogen [42][43][44][45] and identify the feasibility limits to the injection of hydrogen into the grid [46][47][48][49][50]. It should be noted that the power-to-gas systems act as a bridge between gas and electric grids [51,52], which have a mutual dependency.…”
