Bringing advanced heat batteries in residential heat and electric systems closer to market through real life demonstration in different climates

Solutions developed

HEAT-INSYDE advances a ground-breaking closed-loop concept using thermochemical material to a compact domestic heat storage prototype at a Technology Readiness Level of 7 through a user-centric approach with real-life demonstrations in 3 different European climate zones.

Main results

HEAT-INSYDE delivers an affordable, highly compact solution (< 1 m3) with robust, long term (> 25 years) performance. Its hybrid functionality combines compact storage with a highly efficient heat pump effect. The system balances central (grid) and decentral renewable energy supply, allowing configuration in both heat and electricity systems and creating new opportunities for grid flexibility.
