Zero Emission Gas Power Technology Qualification for Industrial Scale ZEG Plants

This project focuses on technology development high efficiency co-production of electricity and hydrogen by the Zero Emission Gas (ZEG) process. Previous projects have identified the ZEG as an especially promising method for producing hydrogen and electri city 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), two technologies that will be developed in this project. Fuel c ells 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, the overall efficiency for the process including separation of CO2 is exceeding 80 %. No othe r CCS technology can demonstrate efficiencies at this level. The main objective for this project is technology qualification of the SOFC stack and CO2 sorption materials to ensure the technology basis for future industrial scale ZEG plants. This will incl ude testing of new SOFC design and materials at realistic operation condition and long term cycling of state of the art sorption materials.
