LongZEG – Zero Emission Gas Power. Long Term System and Material Test (2009-2010)
Project duration: 01.01.2009 – 30.06.2010
Budget: 3.2 MNOK
Funding by: Research Council of Norway, ZEG Power AS, Statoil ASA
Project leader: ZEG Power AS
Partners: ZEG Power AS, Prototech, Statoil ASA
The process combines sorption enhanced (SE) reforming and high temperature solid oxide fuel cells (SOFC) for co-production of hydrogen and electricity with CO2 capture. Fuel cells are in general a very efficient method for converting natural gas to electricity, and by utilizing the excess heat from the SOFC for production of hydrogen, an efficiency exceeding 80 % is reached.
The integrated process has been demonstrated as a 2 kW lab unit (Risavika, June 2008). This unit contains three new technologies developed by the partners in previous ZEG projects; a SE - batch reformer unit, a SOFC stack and an high temperature infrared gas analyser (FTNIR) for in-situ measurements of the gas composition.
The main objective for this project is to verify that the technology is ready for demonstration in a pilot plant by long term testing in realistic environments for the ZEG process. The following sub-goals are defined:
- Long term cycling test of CO2 sorbent materials and reforming catalysts in SE
- reforming conditions
- Long term operation of SOFC at typical ZEG conditions
- Optimisation of the regeneration process for the batch reactor
- On-line gas characterisation by infrared measurements
- Long term experience from system operation
- Establish experimental data for optimisation of heat integration and system design
