The four companies will commission a 25MW natural gas plant by 2014 to demonstrate the system and expect to complete a 250MW full-scale natural gas commercial plant by 2017.
Producing a supercritical carbon dioxide (CO2) stream to power the turbine generator, the system eliminates emission of nitrogen oxides.
Residual CO2 from the process can be used in enhanced oil recovery, which increases crude oil production from oil fields.
NET Power is the initial developer and owner of the technology, while the three new participants will look to bring their own expertise and knowledge for its implementation.
Toshiba will work on high temperature and high pressure turbine and combustor, while NET power and Shaw will handle plant engineering with Exelon looking into the development and operations of the 25MW demonstration site.
