Romania is among the European countries that have rich geothermal water resources. Unfortunately, these resources are of medium and low enthalpy, which makes their uses only direct, for space heating, spa treatments, greenhouse heating and other applications in agriculture and fish farming. However, recent regulations regarding the reduction of greenhouse gas emissions and fossil fuel consumption have led to increased research into the possibility of using these low-enthalpy resources for electricity production using ORC technology. The authors present a case study regarding the generation of electricity through ORC technology, using geothermal water with a temperature of 75°C from a geothermal reservoir located in the north of Bucharest, in the perimeter of Moara Vlăsiei locality. The performance of the installation is studied in relation to the working agents that may be used and the cooling medium available. The optimal operating conditions, for which the maximum electrical power is obtained, are also determined. The study is timely, considering the metropolitan projects to realize in the area a heating system using geothermal water and which can have high energy efficiency through its smart combination with electricity production.

Romania is one of the European countries that has a rich geothermal potential, the main uses of this resource being the spaces heating and thermal baths. Recently, concerns about increasing energy efficiency and limiting greenhouse gas emissions, have determined an increased attention to heating systems using geothermal water. These will play an important role in the future in developing sustainable energies and reducing the use of fossil fuels. The authors present a case study on a heating system in the city of Călimănești, initially using liquid fuel, which was modernized by using geothermal hot water for the preparation of the thermal agent. As geothermal water, with an initial temperature of 95°C, cannot be cooled below 50°C, the authors considered the possibility of using a heat pump to fully exploit the thermal potential of geothermal water, increase the capacity of the system and increase its energy efficiency. The implementation of the heat pump in the district heating system and the results expected to be obtained are discussed. It was considered that the heat pump works in parallel with the heating system, obtaining an increase in its capacity by approx. 60% and an increase in energy efficiency by approx. 30%.
