Advances in seasonal thermal energy storage for solar district heating applications: A critical review on large-scale hot-water tank and pit thermal energy storage systems

Nowadays, buildings consume a large amount of conventional energy sources in European countries and subsequently they contribute significantly to fossil fuels emissions. Therefore, many European countries have introduced several policies to minimize this consumption by transitioning buildings into more energy efficient ones, whereas some other policies focus on integrating renewables into energy systems. In this context, solar district heating...
