NET Power LLC secured funding and project agreements to build a 50 megawatt thermal (MWt), $140 million gas-fired power plant that would produce no air emissions and includes what the North Carolina-based company says will be full carbon dioxide (CO₂) capture.

The project is funded by a combination of cash and in-kind contributions from Exelon Corp. and CB&I.

Toshiba Corp., following several years of development and testing, has begun manufacturing a supercritical CO₂ turbine for the project. Operations, maintenance and development arrangements have been completed with Exelon. Contracts for plant engineering, procurement and construction are in place with CB&I. 8 Rivers Capital, the inventor of the technology, will provide continued technology development services and the intellectual property for the project. The plant will be built at a site in Texas, with commissioning expected to begin in 2016 and be completed in 2017. Design and development is also progressing on the first 295 MW (electric) commercial-scale NET Power plant.

The plant will use a supercritical CO2­ power cycle known as the Allam Cycle, which produces carbon dioxide as a pipeline-quality byproduct. The CO₂ then can be sequestrated or used in enhanced oil recovery, a process that uses carbon dioxide to increase production from mature oil wells while storing the CO₂ underground.
