The current project portfolio contains a variety of technologies that incorporate advanced, clean, efficient coal-based power systems. Several of the projects include power systems integrated with carbon capture and storage (CCS) technology, while one existing power plant will be retrofitted with CCS technology. Two of these projects will also produce high-value chemicals (poly-generation). These projects will demonstrate diversity in technology for both the power generation and carbon capture systems.
The power system portions of these demonstrations include gasification technology from Trig™ (Southern Company), Siemens (Summit Texas Clean Energy), and Mitsubishi Heavy Industries (Hydrogen Energy California). The carbon capture systems will include Linde’s Rectisol System (Summit Texas Clean Energy and Hydrogen Energy California) and Fluor’s Econamine FG PlusSM (NRG Energy). The CO2 captured in three of the projects (Summit Texas Clean Energy, Hydrogen Energy California, and NRG Energy) will be stored through use in enhanced oil recovery.
