“…As can be seen from Eq. (15) in SI, decreasing quality of steam means more natural gas for producing the steam. But, lower quality of steam also means lower enthalpy in steam, leading to lower natural gas consumption.…”

“…Ordorica-Garcia et al [11] and Betancourt-Torcat et al [12] focus on optimizing the costs for energy demands in oil sand industry. Similarly [13][14][15][16] study the carbon reduction technologies from economic aspect but do not detail the estimation of GHG emissions from specific oil sand projects. Other studies [17][18][19] answer different questions and do not suffice for calculating project-specific energy consumption and emissions.…”

“…Around 21 kg-H 2 is required to upgrade one cubic meter of bitumen to SCO, which translates to a hydrogen demand of 4.2 Mt/day to produce 1.26 million bpd of SCO in 2022 [3,4]. Currently, H 2 is produced from the steam methane reforming (SMR) process, using natural gas (NG) as a feedstock [5,6]. Since SMR-based H 2 production has high GHG footprint -9.1-14.49 kg-CO 2 -eq/kg-H 2 [3,[7][8][9][10][11] -there is reason to study alternative ways to produce H 2 for sustainable development of the bitumen upgrading industry.…”

“…In the Central Mining Institute in Poland, UCG studies are carried out on a laboratory and pilot scale targeted to obtain gas with a high hydrogen content (Kapusta and Stańczyk 2011;Smolinski et al 2012;Smolinski et al 2013). Detailed description and an overview of the underground coal methods and application possibilities of this technology are shown in the papers (Yang et al 2008;Liu et al 2009;Olateju and Kumar 2013;Żogała 2014;Janoszek et al 2013). The composition of the gas from UCG differs depending on the type of gasified coal, gasifying agent used, the existing pressure and temperature.…”

Purpose In Poland, coal is the main fuel used for heat production. Innovative clean coal technologies, which include underground coal gasification (UCG), are widely developed. This paper presents the analysis results of life cycle assessment (LCA) and material flow analysis (MFA) of using synthesis gas from UCG for heat production. The paper presents the results of a comparative analysis of MFA and LCA for four variants of heat production, which differed in the choice of gasifying agent and heat production installations. Methods Environmental analysis was made based on LCA with ReCiPe Midpoint and ReCiPe Endpoint H/A method, which allowed to analyse of different categories of the environmental impact. LCA was performed based on the ISO 14040 standard using SimaPro 8.0 software with Ecoinvent 3.1 database (Ecoinvent 2014). Umberto NXT Universal software was used to develop MFA for heat production. LCA analyses included hard coal from a Polish mine and synthesis gas obtained in the experimental installations in the Central Mining Institute in Poland. Results and discussion MFA performed for technology of utilizing gases from UCG have made it possible to visualize materials and energy flow between different unit processes in the whole technological chain. Moreover, the analyses enabled identification of unit processes with the largest consumption of raw materials, energy and the biggest emissions into the environment. It has been shown that the lowest environmental burden is attributed to the technology, which uses high-pressure chamber with gas turbine in which the synthesis gas from UCG is burned and oxygen was a gasifying agent. Analysis of LCA results showed that the major environmental burden includes greenhouse gas (GHG) emission and the fossil fuels depletion. GHG emission results primarily from the direct emission of CO 2 from gas combustion for heat production and electricity consumption used in gasifying agents preparation phase. Conclusions In order to increase the environmental efficiency of heat production technology using UCG, the most important activity to be considered is limitation of dust-gas emissions, including primarily CO 2 removal process and efficiency increase of the installation, which is reflected in the reduction of coal consumption. It is important to highlight that this is the first attempt of MFA and LCA of heat production from UCG gas. Since no LCA has ever been conducted on the heat production from underground coal gasification, this study is the first work about LCA of the heat production from UCG technology. This is the first approach which contains a whole chain of unconventional heat production including preparation stages of gasifying agents, underground coal gasification, gas purification and heat production.
