Using a patented thermodynamic cycle called the Allam Cycle, NET Power is able to generate lower-costpower from fossil fuels than existing power plants while eliminating all air emissions, including carbon dioxide.
Additionally, the CO2 that NET Power plants generate from burning fuel is produced as a high-pressure, high-quality byproduct, ready for pipeline transportation and storage. In many places, this CO2 can be sold for use in enhanced oil recovery (EOR), permanently sequestering the CO2 and providing significant added value for NET Power plant owners.

NET Power plants have several key features that enable them to inherently eliminate all air emissions. This means no carbon dioxide, particulate matter, mercury, SOX or NOX is released to the atmosphere. A NET Power plant’s only major byproducts are liquid water and a high-pressure, high-purity stream of carbon dioxide that is sent into a pipeline for sequestration or utilization in industrial processes.
Power plants are traditionally huge consumers of water. NET Power plants don’t use steam for power production, so they can actually eliminate water consumption for only a slight reduction in plant efficiency.

Working with its owners—Exelon, McDermott, and 8 Rivers — and turbine partner Toshiba, NET Power has built a 50MWth demonstration plant in La Porte, Texas. The facility is a grid-connected Allam Cycle power plant, and it will provide the basis for the deployment of commercial-scale facilities. 300MWe commercial NET Power plants are currently under development, with the first plant expected to be operational as early as 2021.
