Pilot Project Captures 90% of CO2

PR Newswire (US)
PLEASANT PRAIRIE, Wis., Oct. 8 /PRNewswire/ -- We Energies, Alstom
and The Electric Power Research Institute (EPRI) announced today
that a pilot project testing an advanced chilled ammonia process
has demonstrated more than 90 percent capture of carbon dioxide
(CO2) from the flue stream of at a coal-fueled power plant in
Wisconsin. At a press conference at We Energies' Pleasant Prairie
Power Plant, which hosted the project, We Energies Chairman,
President and CEO Gale Klappa, Alstom U.S. President Pierre
Gauthier, and EPRI Senior Vice President Hank Courtright discussed
the demonstration of Alstom's patented chilled ammonia process for
carbon capture. Testing at the pilot facility, using a 1.7-megawatt
(electric) slipstream from the plant, began in early 2008 and will
conclude later this year. The project confirmed the predicted
performance of the chilled ammonia carbon capture system at an
operating power plant. It achieved key research metrics around
hours of operation, ammonia release, CO2 removal levels, and CO2
purity. In doing so, the project demonstrated the fundamental
viability of the carbon capture technology in real-world conditions
such as changes in temperature and humidity, the inevitable starts
and stops of a large power plant, and the environmental hurdles
that go along with using any chemical process. "One of the biggest
challenges facing our industry is the development of cost effective
technology that will allow us to capture carbon from the operation
of power plants around the world," said Klappa. "Today, with the
success we're reporting from the research here at Pleasant Prairie,
the solution is one step closer to reality." Lessons learned at
Pleasant Prairie already have provided critical information for
efforts to scale up effective carbon capture and storage
technologies for new power plants and for retrofit to existing
plants. A scaled-up 20-megawatt (electric) capture system has been
installed at AEP's 1,300-megawatt Mountaineer Plant, where it will
remove an estimated 90% of carbon dioxide emissions from the flue
gas stream it processes, capturing up to 100,000 metric tons of CO2
per year. The captured CO2 will be compressed, pipelined, and
injected into two different saline reservoirs located approximately
8,000 feet beneath the plant site. Battelle Memorial Institute will
serve as the consultant for AEP on geological storage as an
extensive monitoring system will be used to track the extent of the
sequestered CO2 over time. "This project has been a success. It
proved what we needed to know to stay on schedule to commercialize
carbon capture technology for new and existing power plants by
2015, a necessary step to meet ambitious climate change targets
being proposed by policy makers in the U.S. and around the world,"
Gauthier said. "Alstom believes carbon capture, along with energy
efficiency and a full portfolio of low carbon technologies
including renewable power, will all be needed to achieve urgent CO2
reduction goals in a timely manner." Alstom, a leader in carbon
capture technology, is pursuing 10 demonstration projects in six
different countries, including the We Energies project and
partnership at Mountaineer with American Electric Power. The
Mountaineer project is one of two current or planned
post-combustion carbon capture and storage (CCS) demonstrations for
which EPRI has formed an industry collaborative to support
management of testing and evaluations. The EPRI collaborative will
support the integration process/design of CO2 capture technologies
and the monitoring and verification of CO2 storage, and it will
assess the large-scale impacts of CO2 controls and storage on
post-combustion coal-fueled generation. The data collected and
analyzed by the collaborative will support efforts to advance CCS
technologies to commercial scale and provide information to the
public and industry on future electricity generation options. EPRI
is leading or supporting seven Industry Technology Demonstrations
as part of its efforts to help develop a "full portfolio" of
innovative technology approaches needed to make substantial CO2
emissions reductions while minimizing economic impacts. EPRI's
Prism and MERGE analyses (available at http://www.epri.com/) found
that deployment of a full portfolio of advanced technologies,
including CCS, could reduce U.S. electric sector CO2 emissions by
2030 to a level below 1990 emissions. EPRI currently is working on
a global analysis that is expected to show similar energy mix
changes and significant economic impacts. "We Energies, Alstom,
EPRI and 37 other companies worked together to successfully advance
carbon capture technology to the next step in its development,"
said EPRI Senior Vice President Hank Courtright. "EPRI's analyses
show carbon capture and storage will be essential to achieve
meaningful CO2 emissions reductions, and do it in a cost-effective
way while meeting demand growth. Projects like this one, where a
company steps up to lead a project and several more form a
collaborative support it, are critical to advancing the
technologies that we need to reduce the industry's carbon
footprint." To learn more about the Pleasant Prairie carbon capture
