LongZEG – Zero Emission Gas Power. Long Term System and Material Test (2009-2010)

Previous projects have identified the ZEG process as an especially promising method for producing hydrogen and electricity from natural gas with CO2 capture (CCS) in an efficient and cost-effective way.

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
