The capability of storing energy can support grid stability, optimise the operating conditions of energy systems, unlock the exploitation of high shares of renewable energies, reduce the overall emissions and, consequently, limit the environmental impacts of energy production, transformation and consumption.
Energy storage is a very wide and variegate topic in which several aspects – from material and process design, control and optimisation, economic and environmental aspects, specific application, etc. – play a fundamental role.
The present review demonstrates that energy storage technologies are pivotal to address volatility issues in both thermal and electrical RES, to increase the level of energy efficiency by exploiting excess heat and waste heat, to support the development of new technologies, i.e., e-mobility.
Similarly, they estimated that electric storage deployments will increase from 200 GWh in 2019 to about 5065 GWh in 2030 . Applications range from power systems, industrial processes, cold chain, district heating and cooling, buildings thermal managements, etc.
Fernandez et al. classified long-term sensible energy storage based on the energy stored per unit of volume and cost E ∗, expressed by the function shown in Eq. (2), where V and C m are the volume (m 3) and the specific cost (€ / kg) of the material. (2) E ∗ = c p Δ T V C m
Three categories of TES are analysed: sensible, latent, and thermochemical heat storage. Sensible TES are a classical technology which is cheap and widespread. Water tank connected to solar thermal plants is the classical and simplest example for this TES category.
