North Carolina startup NET Power has found a way to power the transition to a CO2-free future without parting ways with fossil fuels with its pioneering turbine technology. The system draws on the Allam cycle, a process for converting fossil fuels using a single turbine into mechanical power while capturing the resulting water and CO2.
The core of Allam’s solution is a new type of gas turbine. The job of a turbine is to convert heat energy into mechanical energy, which can then be turned into electricity. All turbines today use either steam or a mixture of hot gases to transfer energy from one form into another, but the process is inefficient. Allam’s system uses carbon dioxide to achieve heat transfer and gets much higher efficiencies as a result.
