REMOTE will demonstrate technical and economic feasibility of two fuel cells-based H2 energy storage solutions (integrated P2P system; non-integrated P2G+G2P system), deployed in 4 DEMOs, based on renewables, in isolated micro-grid or off grid remote areas. DEMO 1: Ginostra (South Italy): off-grid configuration (island); RES based on hybrid system with PV- generators; residential loads on-site; almost complete substitution of fossil fuels. End-user: ENEL Green Power utility; DEMO 2: (Greece): isolated micro-grid application; RES based on hydro generators; industrial (SME) loads onsite; complete substitution of fossil fuels; avoid costs for new transmission line. End-user: Horizon SA owner of hydro plant; DEMO 3: Ambornetti (North Italy): off-grid configuration (remote Alps); RES based on hybrid system with PV-biomass CHP generators; residential loads on-site; complete substitution of fossil fuels. End-user: IRIS stakeholder of the hamlet; DEMO 4: Nordic Island (Norway): isolated micro-grid application; RES based on hybrid system with PV-wind generators; residential loads+ fish industry on-site; complete substitution of fossil fuels; avoid costs for new transmission line. End-user: Trønder Energi utility. VALIDATE the 4 DEMO units, to enable suppliers, end-users and general stakeholders to gain experience throughout the value chain of the energy storage; DEMOSTRATE the added value of the fuel cell-based H2 energy storage solutions with respect to alternative technologies in terms of economics, technical and environmental benefits; VALIDATE EU-based sub-MW P2P manufacturing solutions to fill the gap in the European energy storage sector while utilising the existing EU know-how already developed in previous consortium among partners; EXPLOITATION and BUSINESS scenarios for the replication of P2P solutions, considering different typologies of micro-grids (isolated or not); DISSEMINATION, build up confidence among stakeholders and raise public interest.

i-STENTORE will examine the integration of diverse storage solutions and their combinations. Innovative storage systems will be showcased and their co-operation with the integrated assets will be co-optimized, placing the reliability, the power quality, the cost-efficient operation and the maximization of the assets’ lifetime as end-goals. i-STENTORE will introduce an umbrella framework aiming to showcase stand-alone and hybrid storage solutions highlighting the multi-purpose use of storage, not only as an energy buffer, but also as an active grid component capable of providing services and contributing to grid resilience, stability and efficient operation. The proposed framework will examine the applicability of versatile storage solutions in various applications covering the mobility, agricultural, industry, household, heating and other sectors, and in different timeframes, creating what-if scenarios for the selection of the optimal storage solutions to serve each individual application in the most effective way, promoting purpose-specific Hybrid Energy Storage Systems (HESS). To achieve this and to ensure a seamless integration in a technology-agnostic and interoperable manner, i-STENTORE will design a Reference Architecture towards an open and flexible storage-enabling European energy system leveraging storage-induced flexibility and facilitating the increased integration of renewable energy sources (RES). i-STENTORE will embrace the introduction of novel business models, towards building positive and attractive business cases for storage, identifying new revenue streams for storage operators and promoting storage systems as a facilitator of the energy transition. This approach will develop and validate the enhanced connectivity of multiple systems at different levels of the energy value chain, incorporating both front-of-the-meter and behind-the-meter solutions, targeting the essential empowerment of new actors and the strategic shift of the role of storage.
