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
