ONSITE (Grant No. 325325) Project Periodic Report Month 18

This document aims at giving to the European Commission a clear progress status of the project ONSITE at month 18 of the project (total project duration 36M). The document focuses on the work done during the project and the deliverables status. The realization of a hybrid system, capable of connecting production and storage devices on the one hand, and of managing and controlling the energy and its exchange with the power grid on the other hand, represents the synergy of two innovative technologies, Solide Oxide Fuel Cells (SOFC) and Sodium Nickel Chloride (SNC) batteries. The ONSITE system is unique in a way that it integrates a high temperature fuel cell system with a molten salt battery. This hybrid offers symbiosis for both technologies where the waste heat from the SOFC can be utilized by the battery, while the battery fast electrical response can handle transient load demand keeping the SOFC system at steady-state. The overall objective of ONSITE project is the construction and operation of a containerized system, based on SOFC/SNC battery hybridisation, that generates more than 20 kW at high efficiency and economically competitive costs. High Temperature SNC batteries are intrinsically maintenance free, show long life and are fully recyclable. The choice of this kind of technology aims thermal integration between the two devices, in order to enhance the total efficiency of the final system, as well. The natural gas (optionally LPG) operated SOFC and the SNC battery will be thermally integrated. Both will provide power for TLC energy stations. Basic research will be pursued on SOFC stacks to reach FCH JU targets in terms of efficiency, duration and costs.
