NET Power, a partnership between 8 Rivers Capital, CB&I and Exelon, is developing a 50 MW thermal (single turbine sized at 300 MW) power plant that will validate a new natural gas power system that produces zero atmospheric emissions, including carbon dioxide.
NET Power is based on a high-pressure, supercritical carbon dioxide oxy-fuel power cycle, which produces cost-effective electric power with virtually zero atmospheric air emissions. Unlike other fossil fuel power generation technologies that release emissions to the atmosphere or employ expensive, add-on carbon capture systems, the primary by-product of NET Power is pipeline-quality, high-pressure carbon dioxide (CO2). The plant, under construction at a site in La Porte, Texas, uses a new supercritical CO2 turbine supplied by Toshiba, a collaborator on the project.
NET Power is a novel, proprietary commercial power system that could challenge all current fossil technologies—natural gas combined-cycle, super-critical coal and integrated gasification combined-cycle (IGCC)—by being both cheaper and cleaner:
- Produces lower cost electricity than existing power plants
- Eliminates virtually all air emissions, with fuel capture of CO2 and nitrogen oxides
- Generates an additional and separate revenue stream from sale of CO2, for enhanced oil recovery or other industrial uses
- Does not need any water with a small efficiency reduction for use of air cooling
