Exelon Generation has joined with CB&I of The Woodlands, Texas, and 8 Rivers Capital of Durham, NC to build NET Power's demonstration power plant that will test a new natural gas power system that produces zero atmospheric emissions, including carbon dioxide.

The plant will be built at a site in Texas, using a new supercritical CO2 turbine supplied by Toshiba, a collaborator on the project. The power plant will demonstrate NET Power's Allam Cycle technology, which uses carbon dioxide as a working fluid to drive a combustion turbine and ultimately produces pipeline-quality CO2 that can be sequestered or used in various industrial processes, including enhanced oil recovery.

The $140 million demonstration project, which includes technology development, power plant design and construction, and a full testing and operations program, is funded by a combination of cash and in-kind contributions from Exelon and CB&I.

Officials from Exelon, CB&I, 8 Rivers, NET Power and Toshiba have finalized technology development and operations and maintenance agreements. CB&I will provide engineering, procurement and construction services.

Toshiba has begun manufacturing the novel supercritical CO2 turbines for the demonstration plant. 8 Rivers, the inventor of the Allam Cycle, will provide continued technology development and the intellectual property for the project. Exelon will operate and maintain the plant.

Project design activities have been ongoing since 2010, and commissioning is expected to take place in 2016.
