CO2 capture RD&D proceedings in China Huaneng Group

Abstract

Abstract CO2 capture is an important carbon management route to mitigate the greenhouse gas emission in power sector. In recent years, China Huaneng Group (CHNG) has paid more attention on CO2 capture technology development and launched a series of R&D and demonstration projects. In the area of pre-combustion CO2 capture technology, GreenGen project initiated by CHNG is the first integrated gasification combined cycle (IGCC) power plant in China. Located in Tianjin, GreenGen aims at the development, demonstration and promotion of a near-zero emissions power plant. An IGCC plant of 250 MW has successfully passed full-scale trial operation. In the next phase, a pre-combustion CO2 capture unit will be integrated into the system. Pre-combustion process based on coal chemical process has been developed with lower costs successfully. Regarding to post-combustion CO2 capture (PCC), in 2008, CHNG built a 3,000 tpa CO2 capture plant, which was the first CO2 capture demonstration plant in China. In 2009, CHNG launched a PCC project in Shanghai with a capture capacity of 120,000 tpa CO2. Recently, Huaneng Clean Energy Research Institute (CERI) and Powerspan formed a joint venture, Huaneng-CERI-Powerspan (HCP). HCP has completed the technology qualification program to supply carbon capture technology for the CO2 capture Mongstad project. Besides these activities mentioned above, feasibility studies and system design for large scale PCC system, have been undertaken by CERI and its partners from Australia, US and Europe.
