“…Field as well as laboratory experiments indicated the ability to store CO 2 in unconventional geothermal systems, related to the precipitation of carbonates and clay minerals, by injecting CO 2 into geothermal reservoirs [14][15][16]. Scientists emphasized the significant ecological benefits of this innovative solution [17,18].…”

This article considers the possibility of using unconventional geothermal resources in enhanced geothermal systems (EGSs) under Polish geological conditions. In order to obtain additional environmental benefits, EGS systems using CO2 as a medium were analyzed. In addition to the production of clean energy, this allows for the geological storage of CO2 during the energy production process. The aim of this paper is to analyze the geological conditions for EGS-CO2 systems. Criteria is established for selecting an optimal location for the implementation of the first pilot installation of this type in Poland. Due to the depth of deposition and predicted thermal and petrophysical parameters, the optimal location occurs in sedimentary rocks in the central part of the Polish Lowland (Krośniewice-Kutno area). However, other favorable zones meeting the established criteria for simultaneous energy production and CO2 sequestration have been identified in northwestern parts of Poland (Szczecin Trough) and in southern Poland, in the area of the Carpathian Foredeep (Upper Silesia region).

“…A review of large-scale CO 2 shipping has been undertaken by Baroudi et al [111] and the transport costs range between USD 10 and USD 167 per tonne CO 2 , depending on the travel distance and transport capacity. An alternative working fluid, supercritical N 2 O, was proposed by Olasolo et al [112] due to its thermodynamics properties but may still not be a viable solution for remote northern communities.…”

Deep geothermal energy sources harvested by circulating fluids in engineered geothermal energy systems can be a solution for diesel-based northern Canadian communities. However, poor knowledge of relevant geology and thermo-hydro-mechanical data introduces significant uncertainty in numerical simulations. Here, a first-order assessment was undertaken following a “what-if” approach to help design an engineered geothermal energy system for each of the uncertain scenarios. Each possibility meets the thermal energy needs of the community, keeping the water losses, the reservoir flow impedance and the thermal drawdown within predefined targets. Additionally, the levelized cost of energy was evaluated using the Monte Carlo method to deal with the uncertainty of the inputs and assess their influence on the output response. Hydraulically stimulated geothermal reservoirs of potential commercial interest were simulated in this work. In fact, the probability of providing heating energy at a lower cost than the business-as-usual scenario with oil furnaces ranges between 8 and 92%. Although the results of this work are speculative and subject to uncertainty, geothermal energy seems a potentially viable alternative solution to help in the energy transition of remote northern communities.
