Longview Power Selects Siemens Energy to Conduct Carbon Capture Study


Erlangen, Germany, Longview Power, LLC, owner of the state-of-the-art power generation facility currently under construction in Maidsville, W.V., has selected Siemens Energy to conduct an innovative study analyzing the applicability of post-combustion carbon dioxide (CO2) capture technology. The Longview Power project includes a new 695-MW rated (net) advanced supercritical pulverized coal power plant equipped with Siemens’ advanced air pollution control equipment. The study will include process design activities focused on the potential application of Siemens’ second generation amino acid salt post-combustion CO2 capture (POSTCAP) process. In addition to the power generation equipment, Siemens provided the air quality control system (AQCS) and therefore is in a unique position to optimize the existing AQCS to accommodate the POSTCAP technology.

Longview is on track to become one of the cleanest, most efficient and most technically advanced coal-fired power plants in the United States. The $2-billion project includes a $500-million investment in sophisticated environmental control systems. Longview Power is owned by Longview Power, LLC, which is in turn majority-owned by GenPower Holdings, L.P.

“GenPower is excited to participate in the advancement of technologies that further our commitment to the development of clean energy resources. We see strong potential for the Siemens post-combustion carbon capture system to advance our clean energy goals,” stated Bob Place, CEO of GenPower Holdings, L.P.

According to the U.S. Department of Energy’s Energy Information Administration (EIA), the amount of CO2 produced from the combustion of fossil fuels in the United States is nearly 5.7 billion metric tons with approximately 33 percent coming from the coal-fired electric power sector. Climate change legislation pending in the U.S. Congress may require a reduction in CO2 emissions from coal-fired power plants. The successful completion of the Siemens POSTCAP feasibility study for Longview can help establish the necessary parameters to allow a demonstration plant to be realized.

“With the results of the study and the support of government funding, we hope to expand upon this agreement and eventually design and install a post-combustion plant demonstration unit,” stated Randy Zwirn, CEO of Siemens Energy’s Service Division. “The United States will need a diverse mix of environmentally compatible sources of power to meet future needs for a clean, sustainable energy supply, and post-combustion CO2 capture can help meet our nation’s ever increasing energy requirements, using the coal resources that are indigenous to the U.S.”

Post-combustion CO2capture technology is part of Siemens’ Environmental Portfolio. In fiscal 2009, revenue from the Portfolio totaled approximately EUR23 billion, making Siemens the world’s largest supplier of environmentally friendly technologies. In the same period, the company’s products and solutions enabled customers to reduce their CO2 emissions by 210 million tons. This amount equals the combined annual CO2emissions of New York, Tokyo, London and Berlin.

The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2009 (ended September 30), the Energy Sector had revenues of approximately EUR25.8 billion and received new orders totaling approximately EUR30 billion and posted a profit of EUR3.3 billion. On September 30, 2009, the Energy Sector had a work force of more than 85,100. Further information is available at
