D2.6 - Report on TCES upscaling

The upscaling and industrialization of a Thermochemical Energy Storage (TCES) system with the RESTORE concept from the laboratory pilot plant to large-scale commercial plants represents one of the most critical steps in further integration of renewable energy technologies, as it encompasses critical engineering challenges to reach higher TRLs at the same time with a promising pathway toward achieving high-density, long-duration energy storage with minimal thermal losses. To fulfil this task components design has to be performed thoroughly concerning almost every part of the whole system. Special attention has to be paid to the design and scale up of:• the reactor with the stirrer and heat exchanger surfaces• the lines to prevent blockage by the suspension• the storage vessels for the different components (suspension, oil, water, nitrogen)• the coupling to the HP/ORC• the control devices
