D1.2 - Report on Requirements and Specifications of the Overall Concept (V2)

The deliverable 1.2 of the RESTORE project aims to provide an extended definition of the RESTORE concept. The report provides information about the Requirements and Specification of the different innovative components presented in the RESTORE solution (especially the thermochemical storage system and the thermodynamic cycles). First, to set the context, the deliverable describes the RESTORE overall concept and its objectives in related to the storage and delivery of energy in both forms (heatand electricity). Then, the deliverable is focused on the definition of the systems that born from the RESTORE concept which are related to the adaptation to the two main fields of applications, one dedicated to large scale applications, while the other focus on small scale applications. For each one, the deliverable provides an extend description, through the definition of the systems main components and its tables for specifications and requirements. However, as the deliverable objective is to focus on the overall concept, the values of the specifications should be adapted, as ad-hoc solutions, considering the boundary conditions imposed by each specific application. In that context, the document provides the general bases of the concept that will be considered as a guide for potential future RESTORE system implementation at higher TRLs.
