/PRNewswire/ -- Southern Company has captured carbon dioxide from one of its power plants for the first time, a milestone that significantly advances the development of technology considered crucial to reducing greenhouse gas emissions from power generation.
The research accomplishment was achieved this month at subsidiary Georgia Power's Plant Yates near Newnan, Ga.
The pilot-scale project at Plant Yates, which uses a capture system developed by Mitsubishi Heavy Industries (MHI), will provide additional process improvements before the technology is demonstrated next year at a much larger 25-megawatt scale at Plant Barry, which is owned and operated by Southern Company subsidiary Alabama Power near Mobile, Ala.
During the pilot at Plant Yates, a small amount of carbon dioxide (CO2) was captured, using a solvent that absorbs CO2, and then returned to the plant's flue gas. At Plant Barry, the carbon dioxide will be compressed and transported via pipeline to deep underground storage formations.
"Capturing CO2 from an operating power plant is an important step forward in our efforts to develop effective and cost-efficient technologies to reduce carbon dioxide emissions while ensuring a continued reliable and affordable supply of electricity for our customers," said Chris Hobson, Southern Company chief environmental officer. "Along with our other carbon capture and storage research initiatives, our success here will help us move closer to the ultimate goal of commercial deployment."
Southern Company is a participant in several major research initiatives to advance the development of carbon capture and storage technology, a key component in the nation's effort to reduce greenhouse gas emissions.
In addition to the projects at Yates and Barry, Southern Company operates the National Carbon Capture Center for the U.S. Department of Energy near Birmingham, Ala., and its subsidiary Mississippi Power is building an advanced commercial-scale coal gasification power plant in Kemper County, Miss., that will include carbon capture and re-use for enhanced oil recovery. Other carbon capture and storage projects are under way or completed at other Southern Company facilities.
The test at Plant Yates will help confirm MHI's emission-control design and provide other findings important to the much larger-scale work next year at the Plant Barry test, which represents one of the industry's largest demonstrations of a start-to-finish power plant carbon capture and storage system.

Southern Company Announces New Partner at National Carbon Capture Center
/PRNewswire/ -- Southern Company, the manager and operator of the U.S. Department of Energy's National Carbon Capture Center, announced today that the technology research center has added another partner, NRG Energy, Inc.
Princeton, N.J.-based NRG joins DOE and a group of leading energy companies that are working to develop and test advanced technologies to capture carbon dioxide from coal-based power plants.
The National Carbon Capture Center, located in Wilsonville, Ala., was established earlier this year to work with scientists and technology developers from government, industry and universities who are creating the next generation of enhanced carbon capture technologies.
The center will conduct testing and analyses in a power plant setting, at a size large enough to provide meaningful performance data under real operating conditions to enable scale-up of the technologies.
Other current partners include American Electric Power, Luminant, Arch Coal, Peabody Energy and the Electric Power Research Institute (EPRI). The center expects to add more partners as its work progresses.
"We welcome NRG to the growing partnership at the National Carbon Capture Center," said David Ratcliffe, chairman, president and CEO of Southern Company. "Carbon capture is an important component of the diverse portfolio of technologies our nation must pursue to meet our energy and environmental challenges. NRG's involvement strengthens our effort to develop and deploy these critical solutions."
The National Carbon Capture Center, scheduled to be fully operational in 2010, is expected to be a focal point of national efforts to reduce greenhouse gas emissions through technological innovation.
"As we look to further decarbonize our fleet and push to develop and deploy these advanced technologies on a larger scale, initiatives like the National Carbon Capture Center will bring us closer to meeting the challenges of global climate change and transitioning to an environmentally sustainable energy future," said NRG President and CEO David Crane.

Southern Company to Demonstrate Technology to Reduce Greenhouse Gas Emissions From Electric Generating Plant
/PRNewswire / -- Southern Company today announced plans to demonstrate carbon capture and sequestration on a coal-fired power generation plant to support the development of technologies for reducing greenhouse gas emissions.
Along with the U.S. Department of Energy (DOE), Mitsubishi Heavy Industries Ltd. (MHI), the Electric Power Research Institute and other partners, Southern Company will build a demonstration facility to capture carbon dioxide emissions from an existing unit of subsidiary Alabama Power's Plant Barry near Mobile, Ala.
Beginning in 2011, between 100,000 and 150,000 tons of CO2 per year - the equivalent of emissions from 25 megawatts of the plant's generating capacity - would be captured for permanent underground storage in a deep saline geologic formation.
The CO2 will be supplied to the DOE's Southeast Regional Carbon Sequestration Partnership (SECARB), which will transport it by pipeline from the plant and store it underground at a site within the area of the Citronelle Oil Field, about 10 miles from the plant, operated by Denbury Resources. The Southern States Energy Board is leading the SECARB effort.
"This project will help increase our knowledge of carbon capture and sequestration, technology we must demonstrate at a commercial level in the effort to reliably generate electricity using coal with reduced greenhouse gas emissions," said David Ratcliffe, Southern Company chairman, president and CEO.
"The main challenge facing deployment of carbon capture and sequestration technology is demonstrating its effectiveness at a large scale," Ratcliffe added. "Our involvement in this and other related projects is part of our commitment to be a leader in finding solutions that make technological, economic and environmental sense."
With carbon capture and sequestration (CCS), CO2 released during the combustion of coal would be separated from the flue gas, compressed, and then permanently sequestered - or stored - deep underground.
The CO2 capture technology to be used in this project, called KM-CDR(TM), was jointly developed by MHI and the Kansai Electric Power Company Inc. It deploys an advanced amine-based solvent that reacts readily with CO2 in flue gas before being separated and compressed so that it is ready for pipeline transport.
The MHI process offers improved performance and lower cost than other existing capture technologies. The process has been demonstrated at smaller scale at a coal-fired generating station in Japan, and is currently being deployed commercially on natural gas-fired systems around the world. This project represents the largest coal-fired demonstration of the technology.
"We are excited to be a partner in this important project that will help further the global goal of reducing carbon dioxide emissions for the benefit of everyone," said Shunichi Miyanaga, executive vice president and representative director general manager of MHI's Machinery & Steel Structures Headquarters. "The confidence our partners have shown in the MHI CO2 capture technology is a testament to the research and development efforts we have undertaken during the past 20 years. Together with our partners, we are ready to deploy and demonstrate to the world the safety and viability of commercial-scale CCS."
An important part of any CO2 sequestration project is site selection through geologic characterization and a robust program to monitor the injected CO2. Therefore, a thorough monitoring process will be deployed to map the movement of the sequestered CO2.
Through this project and others, Southern Company and its partners seek to support the goal of better understanding the impacts of reducing CO2 emissions from electricity generation. The project in Alabama is designed to demonstrate start-to-finish CCS technology, an important step toward commercialization.
Plant Barry, located in Bucks, Ala., has a total capacity of 2,525 megawatts and includes seven generating units -- five coal-fired units and two natural gas-fired combined-cycle units.
Southern Company, an industry leader in technology research and development, is working with the federal government and other partners in several major CCS research projects. In one, Southern Company subsidiary Mississippi Power's Plant Daniel is the host site for a demonstration in which 3,000 tons of CO2 recently were injected into a deep saline rock formation 8,500 feet below ground. Monitoring of its movement deep in the ground and under multiple geological seals is now under way.
