Siemens Energy is to adapt its proprietary process for carbon dioxide capture to the special conditions prevalent in and mode of operation of combined-cycle power plants for the Norwegian utility Statkraft.

The project kicked off in January 2009 and is scheduled to be completed within two years. This technology will then be available for industrial-scale applications.

Siemens is already working on a proprietary process for CO2 capture from the flue gas of coal-fired power plants. “Cooperation with Statkraft will allow us to now further develop this future-oriented technology to also permit its use in gas-fired combined cycle power plants “, Suess added.

Combined cycle power plants are in great demand throughout the world due to their high efficiency and low environmental impact. They do, however, impose stringent requirements on the process used for CO2 capture. Their flue gas has a lower CO2 concentration than that in coal-fired plants while simultaneously exhibiting a high oxygen content, conditions which have a very negative impact on known solvents.

    Siemens has competion in GE’s IGCC system that converts coal into a cleaner burning fuel. This fuel is then burned in a gas turbine combined cycle system to generate electricity. IGCC plants provide a cleaner, economical coal-to-power option.

    From their gasifier technology to their IGCC-capable turbines, GE’s process and power experts develop the most economical and reliable approaches to IGCC technology. GE offers extensive experience and high availability solutions.

    A combined cycle is characteristic of a power producing engine or plant that employs more than one thermodynamic cycle. Heat engines are only able to use a portion of the energy their fuel generates (usually less than 50%). The remaining heat (e.g., hot exhaust fumes) from combustion is generally wasted.
