This paper expounds the policy requirements for the allocation of energy storage, and proposes two economic calculation models for energy storage allocation based on the levelized cost of electricity and the on-grid electricity price in the operating area.
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.
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.
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.
The SOPHIA project has provided HyGear with th knowledge to widen ist technology base for producing hydrogen in future years. SP is a major developer and supplier of SOFC systems. It is constantly improving iis cells, stacks, and systems. The results obtained in the SOPHIA project will assist SP in this efort.
