{{CoalSwarm}}The '''GreenGen power station''' (华能天津IGCC示范电站一期) is a 250-megawatt (MW) integrated gasification combined cycle (IGCC) power plant and proposed 400 800 MW carbon capture and storage (CCS) plant in Tianjin, China.
==Location==
==Background==
GreenGen Ltd. Co. China was established by the [[China Huaneng Group]] and seven other Chinese state-owned companies in January 2006. [[Peabody Energy]] joined the consortium in December 2007 as the only non-Chinese participant in the program. The goal of the GreenGen program in Tianjin is to develop a large-scale [[IGCC]]–[[CCS]] demonstration project in China, at an estimated cost of US$1.5 billion. The program is being carried out in three phases.<ref name=jt>Jeff Tollefson & Richard Van Noorden, [http://www.nature.com/news/slow-progress-to-cleaner-coal-1.10411 "Slow progress to cleaner coal,"] Nature, April 11, 2012.</ref><ref>[http://www.hpi.com.cn/_layouts/mobile/dispform.aspx?List=2d82321e-d34c-47e6-82e5-df973d476116&View=4c10619a-1a03-4bd1-bd48-cba3baf04fdd&ID=376 "华能天津IGCC技术创新 路向何方,"] 2014-9-19</ref>
The first phase is a 250-megawatt [[integrated gasification combined cycle]] power plant, which will convert coal into ‘[[syngas]]’ — a mixture of carbon monoxide and hydrogen — to be burned in specialized turbines to produce electricity. Construction of the plant began in 2009 and was completed in 2012.<ref name=gccs>[http://www.globalccsinstitute.com/project/huaneng-greengen-igcc-project-phase-3 "Huaneng GreenGen IGCC Project (Phase 3),"] Global CCS Institute, accessed December 2014</ref>
The second phase is a pilot plant designed to send a "clean" stream of hydrogen through fuel cells and turbines to produce electricity, with carbon dioxide being captured for industrial use.<ref name=jt/> Construction of Phase II began in early 2014.<ref name=gccs/>
The third phase will be a 400an 800-megawatt power plant with full-scale [[carbon capture and storage]] in underground rock layers. <ref>[http://www.thea.gov.cn/tzlg/a/2012-12-13/1365667288571.shtml "领先世界水平的华能天津IGCC电站示范工程正式投产,"] Tianjin Harbor Economic Area, 2012-12-13</ref> The original planned completion date was 2015 but was then pushed back to 2020.<ref name=jt/> The CO2 may be used for [[enhanced oil recovery]] at the Tianjing Dagang oil field.<ref name=gccs/>
GreenGen was originally seen as a follow-up to the US's [[FutureGen]], whose original start date has also been delayed.<ref name=jt/>
