After the successful completion of phase 1 and award of contract for phase 2, Siemens has been selected by Statoil to participate also in the third phase of the Technology Qualification Program for a full-scale CO2 capture plant at the combined-heat and power plant at the refinery of Mongstad in Norway. This third and last phase of the Technology Qualification Program started late September and will be finished in April 2013.
In Phase 1, Siemens could successfully demonstrate the applicability of the PostCapTM process for the Mongstad carbon capture plant by proving that PostCapTM can be scaled up to full scale, has the required operational regularity and that high capture ratios can be achieved with limited life-cycle costs.
Phase 2 is already partially completed: The sub-tasks of conducting stress tests on the solvent and documenting emission data on an automated laboratory test rig had been performed within the time frame agreed. The remaining task of a 3000-hour performance test at an approved verification pilot plant with flue gas from a gas-fired boiler is ongoing.
The third and final phase, which has now been awarded to Siemens, is the concept phase for the design of full scale CO2 capture at Mongstad. Successful results in the Technology Qualification Program will allow for the potential selection of Siemens' PostCapTM technology in later project stages. "We are proud that Siemens has again been selected for the next round in the technology qualification program for Mongstad. By considering our technology with its inherent advantages for health, safety and environment the project risks will be further reduced ," said Nicolas Vortmeyer, Head of Technology Innovation of Fossil Power Generation at Siemens Energy. He added: "The phased approach for the CCM project is very smart because Statoil and Gassnova can get a deeper understanding of the carbon capture technologies and gain trust in the cooperation with the potential plant supplier. Thus it contributes to eliminating risks in the implementation of first-of-its-kind demonstration projects."
Siemens' proprietary CO2 capture technology uses an amino-acid salt solution as a solvent and has proven to have several advantages compared to other post-combustion carbon capture processes: both low energy consumption and low investment costs as well as nearly zero emissions. Furthermore, the PostCapTM unit can be operated within the common safety standards of a power plant. It is suitable for retrofitting existing plants and new power plants.
