Compact and Sustainable Heat Storage

HEAT-INSYDE aims to advance a ground-breaking closed-loop concept using thermochemical material to a compact domestic heat storage prototype at a Technology Readiness Level (TRL) of 7 through a user-centric approach with real-life demonstrations in 3 different European climate zones. HEAT-INSYDE delivers an affordable, highly compact solution (< 1 m³) with robust 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. This so-called heat battery will be a game changer in the transformation of the built environment, as it accelerates the application of decentralised heat storage in the renewable energy system, both electricity and heat.

To reach the goal of the developed technologies, HEAT-INSYDE combines three main technologies to advance: multicyclic stable thermochemical material, compact thermochemical heat storage systems, and energy management and interfacing. The HEAT-INSYDE consortium mobilizes all the key players relevant to the future manufacturing and distribution chain. The consortium consists of multi-disciplinary partners with full complementarity, i.e. industrial material supply and manipulation, appliances developer/producers, and network/service providers to enable the necessary step to scale-up and commercialization.
