Energy and Industrial Process Systems Engineering

COMHPTES aims to develop innovative heat pump (HP) and thermal energy storage (TES) cost-effective compact technologies, and to demonstrate them up to TRL 5 in a fully integrated flexible and modular system able to supply heat and cold energy on demand for industrial applications, including interfaces with affordable renewable energy systems (RES), waste heat recovery and district networks. The COMHPTES system will address industrial end-users with flexible heat loads and temperature requirements in the ranges from 0.5 to 10 MW-t and 5 to 225°C, respectively, which represent approximately half of the total industrial installations and a quarter of the total process heat consumption in EU. The COMHPTES system will build upon the compactness and modularity of its technologies to best comply with space constraints in industry, and to enable gradual technology adoption, thereby reducing large upfront investments and operational risks.

FLUWS aims to develop and validate a more flexible, reliable, environmentally friendly and cost-effective thermal energy storage (TES) system futureproofed for next generation concentrating solar power (CSP) plants operating at higher temperatures and hybridized with PV, which are recognized as the two main paths for reaching cost-efficiency of CSP in the near future. Specifically, FLUWS validates up to TRL 5 a novel TES concept that ensures elevated thermal efficiency with minimum environmental impact thanks to on the one hand the upcycling of waste and residual materials from the ceramic industry and the use of air as heat transfer fluid, and on the other thanks to building on previous consortium know-how in the development of new cost-effective radial packed-bed TES and materials for high temperature applications. The new FLUWS TES will enable more flexible and modular CSP systems as it will have embedded electric heaters driven by renewable electricity and will be designed for easier integration with compact gas Brayton cycles (i.e. supercritical CO2 and air-driven), thus facilitating the provision of additional services from CSP to the grid and widening the applications of CSP as a competitive technology for combined heat and power in the industrial sector.

HYBRIDplus aims to pioneer the next generation of CSP with an advanced high-density and high-temperature thermal energy storage (TES) system capable of providing a high degree of dispatchability at a low cost and with a much lower environmental burden than the State of the Art. This thermal storage is based on 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. This enables hybridization with PV by acting as an electric heater transforming non-dispatchable renewable electricity into thermal stored energy ready to be dispatched when needed. HYBRIDplus proposes a novel concept to hybridize PV+Cascade PCM-TES with 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 next-generation energy system thanks to higher efficiency and lower LCOE than state-of-the-art technology.

I-UPS validate up to TRL 5 a FOAK high-temperature heat pump, based on Stirling cycles and exploiting a non-toxic, inert, zero ozone depletion potential and zero global warming potential 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. The integrated heat pump configuration will enable higher modularity, flexibility, and efficiency for heating decarbonisation also leveraging waste heat recovery and contributing to the circularity of the industrial sector.
