HYPERGRYD aims at developing a set of replicable and scalable cost effective technical solutions to allow the integration of RES with different dispatchability and intrinsic variability inside Thermal Grids as well as their link with the Electrical Grids, including the development of innovative key components, in parallel with innovative and integrated ICT services formed by a scalable suite of tools for the proper handling of the increased complexity of the systems from building to Local Energy Community (LEC) levels and beyond, accelerate the sustainable transformation, planning and modernization of District Heating and Cooling (DHC) toward 4th and 5th generation. HYPERGRYD also aims at developing real time management of both electrical and thermal energy flows in the coupled energy network complex, including the synergies between them. Therefore, HYPERGRYD aims at three over-arching General Objectives: - To prove Smart Energy Networks as the future of Efficient Energy Management in DHC in synergy with the Electrical Grids in LEC/Smart Cities of the future, - To define the roadmap to design and planning of future DHC as well as the modernization of the existing ones in different climates and RES penetration levels toward 4th-5th generation, -To demonstrate HYPERGRYD RES-based Enabling Technologies, Smart Energy Grid Solutions empowered by new ICT tools and services as the key for this evolution. During the project, the HYPERGRYD?s solutions will be implemented across 4 Live-In-the-Labs cases in 3 representative climates provided by the consortium, with special consideration to their cost effectiveness and potential replicability to finally achieve these 3 main objectives. All these tasks will follow the proposed work program activities to ensure systematic and scientific performance measures, feedback and powerful exploitation.

GEOFIT is an integrated industrially driven action aimed at deployment of cost effective enhanced geothermal systems (EGS) on energy efficient building retrofitting. This entails the development technical development of innovative EGS and its components, namely, non-standard heat exchanger configurations, a novel hybrid heat pump and electrically driven compression heat pump systems and suite of heating and cooling components to be integrated with the novel GSHP concepts, all specially designed to applied in energy efficient retrofitting projects. To make viable the novel EGS in energy efficient building retrofitting, a suite of tools and technologies is developed, including: low invasive risk assessment technologies, site-inspection and worksite building monitoring techniques (SHM), control systems for cost-effective and optimized EGS in operation phase and novel BIM-enabled dedicated tools for management of geothermal based retrofitting works (GEOBIM platform). Furthermore, the project is commited with the application of novel drilling techniques as the improved low invasive vertical drilling and trenchless technologies. GEOFIT brings these technical developments within a new management framework based on Integrated Design and Delivery Solutions for the geothermal based retrofitting process.The IDDS driven process will materialise in the Geo-BIM enabled Retrofitting Management Platform (Geo-BIM tool). By using the 5 demonstration sites as open case studies in 4 countries and climates, featuring different representative technical scenarios/business models, GEOFIT will leverage its key exploitable results, adapted business models and market oriented dissemination for maximizing impact and wide adoption of these novel geothermal technologies and approaches.

The mission of HYSTORE is to develop and validate an innovative set of TES concepts, based on the combination of cutting-edge technology components: ALL-IN-ONE PCM solution, LOW-TEMP PCM HEATING&COOLING solution, PCM HEATING solution and TCM HEATING&COOLING solution. The four novel concepts attain different applications on heating/cooling (H/C), DHW configurations, and further set up optimal conditions for the provision of hybrid – meaning energy and power- services thanks to the development of a smart aggregator and an open-source multi-service platform. The main key features of HYSTORE are: • Technological advancement of thermal energy storage (TES) with up to +150% energy density and -50% CAPEX compared to state-of-art (SoA) • Significant lower design and installation effort thanks to pre-defined and standardized guidelines; • allow TES to be coupled and integrated with grid-level aggregators that can be federated in the context of both single buildings and local energy communities • 4 use case application in different climates both for District Heating/Cooling connected and non DHC-connected buildings with high-impact and replication potential. • LCOS in line with EU targets from IRENA annual reports and SET-plan. HYSTORE puts TES sytems in the path of 0,05€/kW/cycle over around 0,04 €/kWh by 2030, which is competitive with batteries. To reach these goals, HYSTORE leverages on a consortium of 18 entities from 8 different EU countries, highly qualified and leaders in their sectors of activity. This consortium covers the whole value chain of the thermal energy storage, technologies for its interconnection with the grid and its optimal operation by exploiting the flexibility resources. The final goal for HYSTORE is to realise the paradigmatic shift of thermal storage from an auxiliary service to the HVAC system to a service for the building to provide the needed comfort with high efficiency while supporting the grid for effective electric-thermal sector coupling.

HYBUILD will develop two innovative hybrid storage concepts: one for the Mediterranean climate primarily meant for cooling energy provision, and one for the Continental climate primarily meant for heating and DHW production. HYBUILD action is a systematic approach for developing operationally integrated thermal and electric components and systems from TRL4 to TRL6 and beyond. The hybrid storage concepts are based on: a compact sorption storage, based on a patented way to integrate an innovative adsorbent material within an efficient high surface heat exchanger, a high density latent storage, based on a high performance aluminum micro-channel heat exchanger with additional PCM layers, and an efficient electric storage. The balancing of thermal and electrical energy flows will be realized by seamless integration of electric building components in a DC coupled system and by efficient conversion and upgrading of electric surplus and renewable thermal energy sources by compression and adsorption heat pumps. The components will be integrated to realize the full-scale hybrid storages (with overall volume between 1 and 2 m3), which will be properly managed by advanced control and building energy management systems (BEMS), able to optimize the interactions between components and district network. Such a configuration will allow reaching energy savings ranging between 20 and 40%, on yearly basis, both in Mediterranean and Continental climate for non-connected and district-connected buildings. HYBUILD hybrid storages will be used to upgrade existing building configurations and monitored in three different demo sites in near-life operation, both for non-connected and district-connected buildings in different climates.
