SOPHIA MODULE ENERGY STORAGE
Sophia Haussener is an Associate Professor heading the Laboratory of Renewable Energy Science and Engineering at the Ecole Polytechnique F?d?rale de Lausanne (EPFL). Her
A large potential market exists for the SOPHIA technology with production capacities. In 2010 the European Commission has adopted the Communication "Energy 2020 - A strategy for competitive, sustainable and secure energy". It includes five headline targets that set out where the EU should be in 2020.
As a general matter, all the numerical means developed in SOPHIA will be valorized through studies dedicated to the optimization of high temperature fuel cell and electrolyser. They allow to narrow the gap between the laboratory developments and the pre-commercial systems.
In addition, the contact elements and sealing concept have been optimized for SOPHIA cells and validated in several 1-cell stacks. It was shown that at atmospheric pressure, the cell and stack can be operated at high current density (ΔiΔ≥0.6 A/cm²) even at 700°C, which might help in ageing resistance.
Concerning the H2 production, it was observed that the techno-economic optimal configuration is when the chemical process part of SOPHIA plant works with a baseload, the intermittency of the solar power generation being smoothened by the CSP process part.
