Use of renewable sources with thermal accumulation of solar energy for the energy consumption of buildings

Abstract

Today, there is an increasing demand for renewable energy sources in Europe to minimise the carbon footprint and achieve a sustainable energy supply. One of the cleanest and most affordable energy sources is solar energy, which can be used efficiently for heating and hot water in buildings. However, efficient storage and use of solar energy is key. This paper focuses on a comparison of two main solar thermal energy storage systems: Pit Thermal Energy Storage (PTES) and Tank Thermal Energy Storage (TTES). The case studies include an analysis of the effectiveness of these systems in real scenarios, along with their advantages, disadvantages and potential future applications.
