IANOS brings together two Lighthouse (LH) islands (Terceira-PT, Ameland-NL), and three Fellow islands (FI) (Lambedusa-IT, Bora-Bora-FR, Nisyros-GR), all sharing a common vision of decarbonizing their energy systems and be energy independent until 2050. Thirty-four (34) strongly experienced partners from nine (9) European countries, join forces to deliver smart technological, economic and social innovations, providing systemic optimization starting from an Energy Community-centric approach. IANOS adopts an Island Energy Transition Strategy built around three (3) Island Energy Transition Tracks that focus on: a) Energy efficiency and grid support for extremely high RES penetration, b) Decarbonization through electrification and support from non-emitting fuels, c) Empowering Local Energy Communities (LEC). Through IANOS an impressive repository of elements (technologies, tools, methods) will be demonstrated in the two LH islands and within nine (9) carefully defined Use-Cases (UCs) that will lead to: a reduction of fossil fuel consumption by 379.7 GWh/y, an increase in RES utilization by 83.6 GWh/y, increase accuracy of vRES forecasts by >10% and reduce energy bills of end-users by >15%. In total, 900 participants (prosumers/consumers) will be involved in LECs by the end of IANOS. Elements to be demonstrated include: an iVPP operative orchestration toolkit, smart energy routers, hybrid transformers, flywheel storage, biobased batteries, heat batteries, tidal kite, an auto-generative digester and the IANOS Energy Planning and Transition Suite (IEPT). The replication potential of IANOS UCs will be evaluated in the three FIs. Due to their current local energy mix, Terceira and Ameland can particularly act as LHs for geothermal and hydrogen-centered island economies, respectively. To reach all these goals, a total of 121.6M€ will be invested by the 2 LH ecosystems, while another 60.4M€ will be fuelled by the 6 FI ecosystems during IANOS (until 2025).

POCITYF supports the Lighthouse cities of Evora (PT) and Alkmaar (NL) and their Fellow cities Granada (ES), Bari (ΙΤ), Celje (SI), Ujpest (HU), Ioannina (GR) and Hvidovre (DK) to address their urgent need to deliver positive energy blocks and districts in their cities, towards rendering their mixed urban environment (also including the case of cultural protected buildings) into cheaper, better accessible, healthier and more reliable. By demonstrating in overall 10 integrated solutions (ISs), comprising 73 individual innovative elements (technologies, tools, methods), rooted under existing City Information Platforms (CIPs), POCITYF quantifies their value, and connects interests of many different stakeholders in innovative business models, allowing for upscale and replication of those solutions in a form of a validated roadmap for sustainable cities across Europe and world-wide. To achieve this, POCITYF works along 4 Energy Transition Tracks (ETTs), encompassing the ISs according to the role each one serves for. ETT#1 focuses on the examination and application of ISs transforming existing and new building stock into Energy Positive, while ETT#2 focuses on the application of a) grid flexibility strategies and b) storage systems, supported by DSM platforms for optimizing energy flows to maximize self-consumption and reduce grid stress. ETT#3 with its merit of innovation offers the integration of e-Mobility to as well promote the decarbonisation of the mobility sector. The 3 ETTs under the coordination of ETT#4, which links existing CIPs with innovative apps and other instruments, offers inclusive and holistic services for interdisciplinary citizen engagement and co-creation of them with the city stakeholders and industry, towards the development of each city’s own bold city-vision up to 2050. Through POCITYF the two LHs will achieve a local RES penetration of 16.2 GWh/y, energy savings of 2.32 GWh/y and an emission reduction of 9,743 tons CO2eq/y within their districts.
