March 2017 www.coalage.com 21 power technology continued power plant located in Maidsville, West Vir- gina, was commissioned in 2011. Mississippi Power's Kemper County Energy Facility — Honored as Carbon Cap- ture, Use and Storage Pioneer, the 582-MW Kemper facility located in Kemper County, Mississippi, employs Transport Integrated Gasification technology that is expected to reduce CO 2 emissions by 65%. Judges applauded the facility's innovation in the areas of ash removal and CO 2 separation, noting "the technology holds great promise for future new electric power plants." NRG Energy and JX Nippon Oil & Gas Exploration's Petra Nova Carbon Capture Project — Honored as Carbon Capture, Use and Storage Pioneer, the Petra Nova project (see Carbon Capture, p.22) demon- strates commercial-scale deployment of post-combustion carbon capture and is designed to capture approximately 90% of CO 2 emissions from a 240-MW equivalent slipstream of flue gas from the W.A. Parish plant in Thompsons, Texas, southwest of Houston. Judges commended the project's innovative capture technology, observing that it "represents the first large-scale retro- fit of an existing coal-fired power plant." Today's high-efficiency, low-emissions (HELE) coal-fueled generation includes multiple technologies capable of reduc- ing the vast majority of SO 2 , NO x , particu- late matter, mercury and other emissions. Advanced HELE technologies result in a smaller environmental footprint, achieving as much as a 25% reduction in a plant's CO 2 emissions rate. Longer-term investments in next-generation carbon capture tech- nologies are widely recognized as essential to meet long-term global climate goals. The Peabody Energy Clean Coal Awards program was established in 2014 to rec- ognize leadership and improve awareness about the benefits of clean coal technolo- gies. Peabody believes coal will continue to be an important part of the world's energy mix, and responsible use including further deployment of advanced coal technologies can help achieve energy security, economic growth and environmental solutions. The World's Best In 2016, POWER recognized three very dif- ferent coal-fired power plants: Mátra power plant, Visonta, Hungary; National Capital Power Station Dadri, Gautam Budh Nagar, Uttar Pradesh, India; and Tanjung Bin Ener- gy power plant, Johor, Malaysia. They were located in very different regions, climates, and political and economic environments, and they deploy diverse state-of-the-art technologies to address both unique and global challenges. When one thinks about innovation at power plants, they may not immediately think of Hungary, but the country's largest coal-fired plant introduced several unique approaches and was among the first to employ a water-wise ash-handling system. The Mátra power plant's commitment to continual improvement is also seen in the addition of biomass fuel and a solar facility. The noteworthy aspects of the Pow- er Station Dadri, one of the largest in coal-dependent India, included consistent high-performance ratings, as well as newer improvements such as an innovative solar thermal system that supplies some of the site's energy needs. Malaysia has been bucking the fuel transition trend as it adds coal-fired capac- ity, it is deploying the most efficient tech- nology plus pollution controls. The Tan- jung Bin ultrasupercritical project came with an extra-challenging site but still met its schedule and budget. GE Launches Center of Excellence During March, GE announced its new glob- al Powering Efficiency Center of Excellence (COE), which brings together cross-busi- ness experts in its energy businesses to apply a total plant hardware and software solution approach to boost the efficiency of the world's new and existing coal-fired power plants and significantly reduce their emissions. The global COE, headquartered in Baden, Switzerland, will create integrat- ed solutions as well as provide vision and oversight around the world. Regional teams will focus on engineering capabilities and local execution. "By bringing together the combined experience of a cross-business group of ex- perts from GE's Power Services, Steam Pow- er Systems, Global Research Center and Global Growth organizations, we are show- ing operators how they can achieve emis- sions compliance and increase efficiency with their new and existing coal-fired pow- er plants" said Michael Rechsteiner, exec- utive sponsor of the global COE and vice president of product lines for GE's Power Services. The COE aligns with GE's recent study that found carbon dioxide (CO 2 ) emissions from the world's steam fleet can be reduced by 11% when existing hardware and soft- ware solutions are fully applied. Coal-fired power generation provides electricity for about 40% of the world. It also accounts for nearly 75% of the electricity sector's carbon emissions because many plants are older and inefficient. "While GE supports the increased use of renewable energy sources, we also real- ize the need for flexible and efficient coal Russell Ray, chief editor of Power Engineering magazine, presents David Greeson, NRG Energy's vice president of development, and Takeo Tanei, vice president of JX Nippon Oil & Gas, with a 2016 Peabody Energy Clean Coal Award for Carbon Capture, Use and Storage Pioneer.
