Minimal Size Thermal and Electrical Energy Storage System for In-Situ Residential Installation

Descrizione del progetto

Soluzione edilizia innovativa per immagazzinare calore

Gli edifici nelle città europee devono migliorare la loro efficienza energetica per contribuire agli obiettivi dell’UE in materia di energia. Un modo per realizzare tale obiettivo consiste nell’immagazzinare energia termica attraverso soluzioni innovative integrate nelle strutture esistenti. Il progetto MiniStor, finanziato dall’UE, sta sviluppando un avanzato sistema integrato compatto che immagazzina calore. La soluzione è adattata al parco edilizio esistente nelle città dell’UE e fornisce riscaldamento, raffreddamento e stoccaggio dell’elettricità sostenibili. Questo sistema è completamente innovativo poiché utilizza fonti di energia rinnovabili a base solare. La sua gestione è garantita da un sistema di gestione dell’energia dell’edificio connesso all’IoT. Il progetto si propone di ridurre notevolmente il consumo energetico negli edifici residenziali offrendo stabilità e prestazioni elevate.


The EU building stock has large potential to increase its energy efficiency with solutions that can be integrated to existing dwellings and through different measures. One of them is optimizing the use and management of thermal energy by allowing it to be stored, levelling demand peaks and increasing use of renewables affected by intermittency such as solar-based heating. The MiniStor project aims at designing and producing a novel compact integrated thermal storage system for achieving sustainable heating, cooling and electricity storage that can be adapted to existing systems in residential buildings. It is based on a high-performing CaCl2/NH3 (calcium chloride/ammonia) thermochemical material reaction combined with parallel hot and cold phase-change materials for flexibility and usage year-round. It also stores electrical energy in a Li-ion battery that responds to grid signals and can sell to the electrical grid. The system is managed by a smart Building Energy Management System that connects to the Internet of Things. The system can have as input energy obtained from a variety of renewable energy sources such as hybrid photovoltaic thermal panels. This arrangement is demonstrated and validated in four demonstration sites (Ireland, France, Greece and Hungary), testing its effectiveness at different local climatic conditions and facilitating market replication. The system provides stability, performance and use of at least 20 years, an estimated compact storage material volume of 0.72 m3, reduced net energy consumption in a building by at least 44% and a return-on-investment period of 6.7 years, using high energy density storage materials that reach storage densities up to 10.6 times higher than water.
