SCO2OP-TES – sCO2 Operating Pumped Thermal Energy Storage for grid/industry cooperation

SCO2OP-TES project aims to develop and validate up to TRL5, in UNIGE lab hosted in Tirreno Power (TP) Vado Ligure Combined Cycle power plant (CCGT), the next generation of Power-to-Heat-to-Power (P2H2P) energy storage solutions. SCO2OP-TES solution is able to guarantee affordable long duration (>10hrs) and large scale energy storage (multi MW/MWh) to facilitate bulky RES integration in EU energy systems as well as to facilitate large scale integration of RES and to convert traditional power plants (CCGT, CHP) – both standalone and those in industrial parks - into flexible renewable energy plants. This will be crucial particularly in a future scenario where their role will be more and more different and industrial process will be more and more electrified.

Background

EU energy grids and systems and the requirements to manage them are changing. EU is targeting to strongly reduce its emissions in the energy and industrial sector and such energy transition is mostly having two protagonists: RES and promotion of electricification. Electricity storage has a key role in this transition, nevertheless, this “EU RES driven electrification campaign” cannot be managed by “INVERTER DRIVEN” storage only (like batteries or capacitors or electrolysers/power-to-hydrogen). Balancing the grid is mandatory in order to allow for the targeted RES penetration in the grid. This is impossible to be done via battery/Power-to-hydrogen only from an environmental and costs, thus reliable alternatives (able to provide proper grid services to EU RES based energy system too) have to be found.

SCO2OP-TES promotes a new technological paradigm based on Thermally integrated- pumped thermal energy storage (TI-PTES) with sCO2 cycles for long-duration grid scale storage as well as, and where available, concurrent utilization of freely available heat like thermal RES or industrial waste heat.

Aim and Objectives

The main goals and objective of SUSHEAT is to test technologies and validate models that can become the starting point for the future replication and scale-up of Power to Heat to Power (P2H2P) energy storage technologies as pivotal energy storage. To achieve that the project will:

  • Develop and validate sCO2 based P2H2P cycles performances in UNIGE-TP site.
  • Design and prototype innovative high temperature TES and sCO2 turbomachinery for sCO2 P2H2P storage cycles
  • Develop and validate models (dynamic, thermo-economic, grid impact) for SCO2OP-TES replication.
  • Demonstrate economic, safety and environmental sustainability of SCO2OP-TES.
