The CREATE project aims to tackle the thermal energy storage challenge for the built environment by developing a compact heat storage. This heat battery allows for better use of available renewables in two ways: 1) bridging the gap between supply and demand of renewables and 2) increasing the efficiency in the energy grid by converting electricity peaks into stored heat to be used later, increasing the energy grid flexibility and giving options for tradability and economic benefits. The main aim of CREATE is to develop and demonstrate a heat battery, ie an advanced thermal storage system based on Thermo-Chemical Materials, that enables economically affordable, compact and loss-free storage of heat in existing buildings. The CREATE concept is to develop stabilized storage materials with high storage density, improved stability and low price, and package them in optimized heat exchangers, using optimized storage modules. Full scale demonstration will be done in a real building, with regulatory/normative, economic and market boundaries taken into account. To ensure successful exploitation, the full knowledge, value, and supply chain are mobilized in the present consortium. It will be the game changer in the transformation of our existing building stock towards near-zero energy buildings.

CREATE will create viable supply chain by bringing together multiple scientific disciplines and industry. In other words, CREATE envisions a multi-scale, multi-disciplinary and multi-stakeholder approach.

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. HEAT-INSYDE delivers an affordable, highly compact solution ( 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. The proposal is based on two recent technological breakthroughs. The first concerns a multicyclic stable thermochemical material with a high energy density that can be produced on(semi-)industrial scale at low costs. The second concerns a reactor principle patented by two partners TNO and TU/e that uses the full potential of the first-generation thermochemical material. The effective energy density on a system level surpasses the state-of-the art water storage solutions by a factor of at least 10. The HEAT-INSYDE consortium is industry dominated and mobilizes all relevant stakeholders in the value chain: ranging from basic material production, material manipulation, reactor design and manufacturing, energy system integration to municipalities and real end-users. The consortium includes the City of Eindhoven, bringing a large-scale pilot opportunity and a national funding multiplier. The knowledge base consists of TNO, CEA and Eindhoven University of Technology (TU/e), all having an excellent track-record in thermal storage technologies and EU projects in this area.
