There is a strong demand from EU to decarbonise freight transport. RHeaDHy will contribute to this by developing high-performance hydrogen (H2) refuelling stations. RHeaDHy aims at fully implement and validate new refuelling protocols that will allow to refuel 100kg H2 trucks in 1Omin. Partners will design and assembly a new very high flow refuelling line for 700bar H2 truck. To do so, they will develop missing key components needed to reach the mean flow target of 170g/s (300g/s at peak). The unique RHeaDHy comprehensive approach will guaranty an optimal design of components and refuelling line by gathering in the consortium best-in-class partners manufacturing all the components downstream high-pressure refuelling station storage to vehicle storage. This approach will allow to choose the optimal trade-off on constrains repartition among components and to fully consider vision of real vehicle constrains. New implemented refuelling protocols are based on previous work (PRHYDE) and standardization committee work, and involve calculation of refuelling coefficients specific to vehicle storage that need to be derived from hundreds of simulations. This extensive simulation work will be performed on refuelling model validated in previous European projects. To dedicate at least 1.5 years to an extensive test campaign, components and refuelling line design, manufacturing and assembly will be achieved within 2 years. 2 refuelling stations will be installed in France and Germany within the first 2.5 years. 2 truck storage test systems will be used to test and validate refuelling protocols on full scale storage. This work will allow to provide feedback from the field to significantly contribute to the establishment of standards on refuelling interface components and protocols. RHeaDHy will then represent a significant step forward to unlock H2 truck market by allowing wide and performant refuelling station network based on European alternative fuel infrastructures ambition.

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.
