WP1 – Materials operation conditions and their feasibility studies
The goal of this deliverable is to fix the parameters relevant for the heat exchanger design (mass flow, temperatures and pressures). In order to obtain this data, a Brayton cycle needs to be selected. Because this cycle is not commercially applied yet, there are many options described in the literature. The supercritical CO2 Brayton cycle for COMPASsCO2 should have a very high efficiency, as this is one key requirements of the Work Program of this project1.
The aim of this deliverable is to determine the operating conditions in the particle cycle, defined
by the particle- sCO2 heat exchanger (HX), the solar field, the receiver and the thermal energy
storage (TES) system.
Under the second version, the heat exchanger design has been reviewed, namely sections: 3.2 (process parameters and technical limitations), 3.3 (material selection) and 3.4 (heat exchanger design).

WP7 – Communication, dissemination and exploitation
This deliverable outlines the communication and dissemination activities performed within the framework of the COMPASsCO2 project. Different aspects are covered, targeting both internal (between the project partner and the European Commission (EC)) and external communication with all project stakeholders, including EC obligations regarding H2020 communication activities.
