“…By pursuing clean energy alternatives, national and local energy policies will move toward intelligent grids and zero-carbon cities [4,5]. As stated in the literature [6][7][8], there are some critical challenges associated with renewable energy because of fluctuating power production and the mismatched supply/demand for electricity. Based on these tasks, the key role of an energy storage system is essentially to meet the energy demand of the building and make the building more energy-independent [9][10][11][12].…”

Despite renewable energy source integration being a well-established requirement in international policies, energy systems still face some unresolved issues, including the intermittence of production. To tackle this problem, a viable solution could comprise the off-peak storage of electricity production excess, to be consumed later during peak-load hours. The transition from the diffuse pattern of centralized generation to the distributed model, involving energy communities, suggests an additional aspect to manage: the spatial constraints of systems for domestic applications. Compressed-air energy storage represents a promising Power-to-Power technology for small-scale energy integration. This study proposes the application of a gas–liquid energy storage system (GLES) in a residential building, using renewable energy excess from a photovoltaic (PV) array. The performance of the proposed system, whose operation involves the compression of the gaseous mass through a piston operated by mineral oil, was evaluated through energy analysis performed simulating the devices and their coupling with the load profiles of the building. The thermodynamic model of storage was validated using data from an experimental campaign on a prototype. A sensitivity study, acting on the features of the system, such as the compression rate and vessel size, allowed us to compare the absorbed PV energy excess, the coverage of the building energy demand during the expansion phase, and the electrical efficiency of a daily cycle. The results obtained, together with the related economic analysis, were used to quantify the market potential of the proposed solution, to be exploited as a mechanical alternative to conventional electric batteries in dwellings.

“…Sensible heat storage is generally the easiest and cheapest way to store energy, but it is also the less efficient at the low temperatures that are typical of the building components and energy systems. Thermochemical heat storage could reach the highest energy storage densities 2 , but are typically more expensive 3 and complex to manage.…”

The need for energy efficiency in building components is constantly increasing, as the current legislation is constantly pushing to decrease the overall energy demand and increase the share of renewable energies in buildings. In this framework, the use of Phase Change Materials (PCM) in construction elements is a powerful tool both to reduce the energy consumption and to improve the integration of renewable energy sources. PCM could be applied both to the building envelope and to the building energy system. In the latter, PCM are typically applied in energy storage elements, exploiting their ability to accumulate and release heat according to the energy need of the building. In this work, the thermal behavior of PCM under dynamic conditions is investigated using three methods based on infrared thermography. The accurate knowledge of the thermal behavior of PCM, obtained through the experimental measurements, is crucial for the design of energy storage elements, as the thermal behavior of PCM-based storage components impacts the overall design of the building energy system.
