I-UPS aims to develop and validate a first-of-a-kind (FOAK), cost-effective and reliable high-temperature industrial heat pump fully integrated in a flexible energy system for industrial medium temperature (~400°C) heat decarbonisation. I-UPS validate up to TRL 5 a first-of-a-kind high-temperature heat pump (HTHP), based on Stirling cycles and exploiting a non-toxic, inert, zero ozone depletion potential (ODP) and zero global warming potential (GWP) fluid, able to deliver decarbonized heat up to 400°C. No other commercial alternatives are available achieving this heat delivery temperature at efficiencies higher than 100%. The developed heat pump provides enhanced performance thanks to the optimization of key subcomponents, such as optimized static and dynamic sealing solutions and compact heat exchangers enabled by genetic algorithm based design optimization and additive manufacturing techniques. I-UPS provides also a seamless integration of the developed high temperature heat pump in flexible energy systems including molten salts based thermal energy storage (TES) for on-demand decarbonized industrial heat based on RES electricity. This effective integration will be attained thanks to the design and development of purposely-optimized compact heat exchangers (pressurized gas to molten salts) which will ensure reliable high temperature operation and fast ‘plug-and-play’ installation. The integrated heat pump configuration proposed by I-UPS will enable higher modularity, flexibility, and efficiency for heating decarbonisation also leveraging waste heat recovery and contributing to the circularity of the industrial sector. I-UPS will contribute to heating flexible electrification, permitting a broader penetration of RES and facilitating and maximizing the market penetration of heat pumps in industrial contexts.

HYBRIDplus:Advanced HYBRID solar plant with PCM storage solutions in sCO2 cycles. HYBRIDplus aims to pioneer the next generation of CSP with an advanced innovative high-density and high-temperature thermal energy storage (TES) system capable of providing a high degree of dispatchability at low cost and with much lower environmental burden than the State of the Art. This thermal storage is based in the Phase Change Material (PCM) technology in a cascade configuration that can reproduce the effect of a thermocline and integrates recycled metal wool in its nucleus that provide hybridization possibilities by acting as an electric heater transforming non-dispatchable renewable electricity such as PV into thermal stored energy ready to be dispatched when needed. HYBRIDplus proposes a novel approach to concentrated solar power with a PV+Cascade PCM-TES CSP configuration based on a high temperature supercritical CO2 cycle working at 600 ºC. This new plant is called to form the backbone of the coming energy system thanks to a higher efficiency and lower LCoE than state-of-the-art technology, and in addition to other benefits such as full dispatchability reached with the hybridization in the storage that allow higher shares of variable output renewables in the energy system and environmental friendliness (lower CO2 emissions, minimum water consumption, enhancement life cycle impact).

SCO2OP-TES project aims to develop and validate up to TRL5 in UNIGE-TP lab the next generation of Power-to-heat-to-power (P2H2P) energy storage able to guarantee long duration and large scale energy storage to facilitate bulky RES integration in EU energy systems as well as to enhance fossil based power plants flexibilization and facilitate grid integration of EU industries. SCO2OP-TES promotes indeed a new paradigm where industrial WH (even at low temperature like 150-200°C) can be used not only to produce power via ORC or sCO2 Cycles, but to operate P2H2P storage systems more efficiently and grid flexibly. The consortium is composed by innovative SMEs and acknowledged EU RTOs, motivated to realize the first sCO2 PTES pilot plant in Europe. Leveraging experiences from previous EU Funded projects (SHARP-sCO2, CO2OLHEAT, SOLARSCO2OL etc.) as well as from acknowledged RTOs (UNIGE, CVR, KTH, POLIMI, CERTH, UoB) and industrial partners (EDPP, EDP-NEW, HERON,), SCO2OP-TES the potential of “sCO2 BASED CARNOT BATTERIES” based on innovative Molten Salt TES (KYOTO, RPOW) and sCO2 HEXs (AL) and turbomachinery (ENOGIA, SIT) targeting to assess the potential benefit of valorising local WH to optimize round-trip-efficiency and reduce TES size/CAPEX while optimizing local grid/power plant flexibility needs. Via its pilot and replication campaign (involving further CCGTs in Greece and Portugal), SCO2OP-TES promotes the role of P2H2P as key enabling long duration/large scale energy storage technology to boost RES integration in EU energy systems. PC-TECO will develop and validate key enabling technologies (HEXs, turbomachinery, TES) and modelling approaches (Dynamics, thermoeconomic, grid flexibility potential assessment) to make EU leader in the field of P2H2P solutions, boosting WH Recovery as well as fostering a storage solution based on rotating-machine and therefore more grid flexible and environmentally friendly if compared to battery or power-to-H2 storage solutions.
