TECHNICAL ADVICE
Technology
Advantages:- Large experience, oldest system test program- Inherent strength and tolerance to rapid temperature change- High electrical efficiency on biogas- Steam-reforming before stack (in the case of biogas can work as a fuse in electrical circuits, and
protect the stack, the most expensive part of the SOFC system)- System develop for industrial purpose (up to MWs)- Maintenace from Europe
Disadvantages:- Steam-reforming with recirculation through an ejector, little possibilities of changing the nominal
CO2 percentage.- Cost per kW high
Experience SOFC systems
4 units delivered to the field (Powerco, Szencorp and EWE), 10 for EWE in 2007
Experience with biogas
They can run a known composition through a test station
