Novel concepts for CO2 capture

This paper describes the possibilities for power generation with CO2 capture using envisaged key technologies: gas turbines, membranes and solid oxide fuel cells (SOFCs). First, the underlying programs in the Netherlands and at ECN are introduced. Then the key technologies are introduced, and concepts using these technologies are discussed. A literature overview of systems for power generation with fuel cells in combination with CO2, capture is presented. Then a novel concept is introduced. This concept uses a water gas shift membrane reactor to convert the CO and H-2 in the SOFC anode off-gas to gain a M rich stream, which can be used for sequestration without elaborate treatment. Several implementation schemes of the technique are discussed such as atmospheric systems and hybrid SOFC-GT systems. (C) 2004 Elsevier Ltd. All rights reserved.
