“…The great potential of geothermal resources used for electric power generation has lately been recognized more and more [7]. However, geothermal heat has been widely used directly for centuries by humans and animals, and can be found in various regions of the world [8]. Heat appears on the earth's surface in various forms that affect the way it is used.…”

“…where: TC-transport and work cost, EUR/year M-TES.EX-number of M-TES exchanging per year TWC-total work cost, EUR/h TfCMs-time for M-TES exchanging, min UTT-unit transport time, min/km TTC-total transport cost, EUR/km dist.-distance between building and Geothermal Base Station, km THD-Total heat demand for the building, kWh/year To use geothermal heat with the use of M-TES, every household needs to have two heat containers; while one of them is used to supply heat to the building, the other one is charged at the charging station in Geotermia Podhala ńska S.A. (in the Geothermal Base Station). The cost of a single container is determined from the following relationship: M − TES.P = Phase change material cost + container cost + trailer cost (8) LCOH.OS in the calculations was adopted in the interval from 0.05 to 0.25 EUR/kWh. LCOH.OS was not clearly defined because it can differ for every building.…”

Techno-Economic Assessment of Mobilized Thermal Energy Storage System Using Geothermal Source in Polish Conditions

The paper considers technical and economic possibilities to provide geothermal heat to individual recipients using a mobile thermal storage system (M-TES) in Polish conditions. The heat availability, temperature and heat cost influence the choice of location—Bańska Niżna, near Zakopane in the southern part of the Poland. The indirect contact energy storage container was selected with phase change material characterized by a melting temperature of 70 °C and a heat storage capacity of 250 kJ/kg, in the amount of 800 kg. The economic profitability of the M-TES system (with a price per warehouse of 6000 EUR, i.e., a total of 12,000 EUR—two containers are needed) can be achieved for a heat demand of 5000 kWh/year with the price of a replaced heat source at the level of 0.21 EUR/kWh and a distance between the charging station and building (heat recipient) of 0.5 km. For the heat demand of 15,000 kWh/year, the price for the replaced heat reached EUR 0.11/kWh, and the same distance. In turn, for a demand of 25,000 kWh/year, the price of the replaced heat source reached 0.085 EUR/kWh. The distance significantly affected the economic profitability of the M-TES system—for the analyzed case, a distance around 3–4 km from the heat source should be considered.
