Renewable energy, particularly from photovoltaics, is becoming increasingly prominent in the Czech Republic. However, this type of energy is heavily weather-dependent: overproduction is common in the summer months, while production in winter cannot meet the demand for heat pumps in residential applications. This contributes to high price volatility in the energy market and decreases the profitability of domestic installations. Underground thermal energy storage may become crucial to regulating the market and constitute an affordable way to store summer energy overflows in the form of heat, which can be used in wintertime to heat buildings at a fraction of the price. This thesis work will explore the current state of the art in underground thermal energy storage technologies for residential or district applications and propose a modeling framework to understand the efficiency of such applications in the present and future climate conditions of the Czech Republic.
