Clean Highly Efficient Offshore Power with CO2 Capture (CHEOP-CC)
Prototech AS , Equinor,
The main objective of the CHEOP-CC project was the development of highly efficient energy production for offshore applications based on fuel cells. The system is based on steam reforming of natural gas where during the process the hydrogen is separated through hydrogen separation membranes.
The hydrogen is then delivered to the HT-PEM producing electricity while the remaining carbon rich fuel is converted in the SOFC, which also supplies heat to the steam reforming process. Oxygen is separated from the hot air stream in a modified oxygen pump based on SOFC technology and used for the final afterburner process of the fuel. Thus, the exhaust is only H2O and CO2 which is easy to separate for CO2 storage.
The work and the results obtained during the project are a) designing and CFD analyses of a stack/reformer interface and the lab verification of the CFD model; b) study of the potential SOFC materials to be used as oxygen pump, design and lab testing of the oxygen pump; c) analysis of membranes and concepts for separation of hydrogen from natural gas; d) study of compact and light weight electrical power conversion systems; e) balance of plant components for the CHEOP-CC concept; f) cost analyses.
