Sažetak
In this work the feasibility of using the coaxial borehole heat exchanger (cxBHE) of deep geothermal wells for simultaneous production of heat and electricity is investigated. Coaxial borehole heat exchangers have advantage for being the single well-system and disadvantage for having lower heat transfer efficiencies when compared to conventional deep geothermal systems with production and injection wells. System consists from thermal and electricity demand, one or more geothermal deep wells, cxBHE's and cascade utilization system for production of electric and thermal energy. The system cxBHE-reservoir is simulated with FeFLOW. Surface equipment is modelled with the in-house model RES2GEO. Theoretical simulations are performed over the one-year time horizon taking into account a single-hour time step. Simulation is providing the detailed in-depth data for analysis of heat transfer which can be used to mitigate the skin effect in vicinity of cxBHE. Also, possibilities for using the high-temperature reservoir as a seasonal heat storage is analyzed. Output data can be used for cost-effective management and design of the new or revitalization of existing wells for decarbonized energy supply.
