The novelty of this small-scale solar plant prototype consists in the use of molten salts (MS) both as fluid carrier and thermal energy storage medium. An eutectic mixture of NaNO 3, NaNO 2 and KNO 3 has been used allowing a 10 kWh energy storage accomplished with two 50-L tanks.
The recipe for success in the short term will be offering a mix of new and diverse small-scale energy storage options and community micro-grids, complemented by a modernised, smarter grid to ensure reliability and round-the-clock power – the big and the small working together to ultimately, drive a more distributed approach to decarbonise
In 2019, as reported by Fig. 4, the PUN values varied between 0. 01 – 0. 12 €/kWh and its daily trend is recurrent throughout the year. As it is highlighted by the same figure, its value has skyrocketed starting from 2021 due to the energy crisis. Indeed, from 0.05 € /kWh of January 2019, it has achieved a value of 0.4 € /kWh in December 2022,
Two ways to ensure continuous electricity regardless of the weather or an unforeseen event are by using distributed energy resources (DER) and microgrids. DER produce and supply electricity on a small scale and are spread out over a wide area. Rooftop solar panels, backup batteries, and emergency diesel generators are examples of DER.
Unfortunately, large-scale CAES plants are very energy inefficient. Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during

Most solar energy storage systems have a lifespan between 5 and 15 years. However, the actual lifespan depends on the technology, usage, and maintenance. Lithium-ion batteries generally have a longer lifespan (around 10-15 years), while lead-acid batteries may need replacement after 5-10 years (Dunlop, 2015).
